Terms of service.

You must be at least 18 years old to use the Service. If you use the Service on behalf of a company or other entity, you represent that you have authority to bind that entity, and “you” refers to the entity.

You are responsible for your account credentials and API keys, for keeping them confidential, and for all activity that occurs under them, whether or not authorized by you. Notify us promptly at hello@lyrenth.com if you suspect unauthorized use. We are not liable for losses arising from compromised credentials that you failed to safeguard.

You agree to provide accurate account information and to keep it current.

Lyrenth provides the AI-readable web index and related services, delivered via API and dashboard.

“Lyrenth” refers to our commercial service. The underlying AIWebIndex open specification (User-Agent identifier, AIDocument format, verification mechanisms) is published openly and intended for formalization at aiwebindex.org over time. The specification is unpatented and freely implementable. Lyrenth is the reference implementation, not the only one. Nothing in these Terms restricts independent implementation of the open specification; everything in these Terms governs use of our Service.

Current self-serve plans are published at /pricing. As of the effective date they include:

• Free: 2,000 successful AIDocuments per month.
• Starter Beta: 20,000 successful AIDocuments per month.
• Pro Beta: 200,000 successful AIDocuments per month.

Successful AIDocument responses count against your monthly quota. Failed requests, rejected requests, and asynchronous submit-only crawl requests do not count unless a feature's product page states otherwise. When your monthly quota is reached, further requests are rejected until the quota resets at your next monthly cycle or you upgrade to a higher plan; you will be notified when the limit is reached. This applies to all plans, including paid tiers.

Features, limits, and pricing may change over time. Existing beta subscribers keep their beta price for the life of their continuously active subscription once public pricing launches; a lapse or cancellation ends beta pricing eligibility.

Paid self-serve plans are monthly subscriptions billed through Stripe, which acts as the merchant payment processor for checkout, payment-method storage, invoices, taxes, and billing-portal operations. Lyrenth does not store full card numbers.

Subscription access is tied to the subscription state we receive from Stripe via Checkout and webhooks. If a payment fails, is disputed, or a subscription becomes past due, unpaid, canceled, or otherwise inactive, we may reduce the account to the Free tier, suspend paid features, or restrict API access until the issue is resolved.

You may cancel a paid subscription at any time through the billing portal. Cancellation takes effect at the end of the current paid billing period unless Stripe or our support team indicates otherwise. Monthly quotas reset on the account's billing cycle or calendar quota window shown in the dashboard.

Refunds are not issued for partial billing periods. If a billing error occurs on our side (duplicate charge, incorrect amount, or a clear failure on our part), we will refund or correct it proactively. Otherwise the standard model applies: cancel anytime, the paid plan stays active through the end of the current cycle, then the account drops to Free.

Custom, enterprise, corpus, export, or data-license arrangements are not governed by these self-serve terms alone; they require a separate written agreement, which controls in the event of conflict.

You agree not to:

• use the Service to access websites or content you do not have the right to access;
• circumvent, or use the Service to circumvent, technical access controls, paywalls, authentication, or rate limits of any third-party site;
• ignore stated rate limits or access restrictions of the Service itself;
• use the Service for unlawful activity, including infringement, harassment, or unlawful surveillance or data collection;
• harm, disrupt, overload, probe, or interfere with the Service or any third-party systems or infrastructure;
• reverse-engineer, replicate, redistribute, sublicense, resell, or create a competing index or dataset substantially derived from the Service, except as expressly permitted in Section 11 or by separate written agreement;
• attempt unauthorized access to accounts, systems, or infrastructure;
• misrepresent your identity or affiliation, or rotate accounts, keys, or identifiers to evade quotas, suspensions, or refusal lists.

You must comply with all applicable laws, including copyright, computer-access and anti-circumvention, data-protection, and privacy laws.

We may investigate suspected violations and may suspend or restrict accounts during an investigation.

You are responsible for the URLs you submit, the content you request as AIDocuments, and your use of the responses we return.

By submitting a URL to the Lyrenth API (via POST /v1/aidocument, GET /v1/document, or any endpoint accepting a URL parameter), you represent and warrant that:

• you have the right to request retrieval of that URL on your own behalf;
• your retrieval complies with the source site's applicable terms of service, including rate and use restrictions;
• your retrieval complies with the source site's robots.txt directives, where those directives apply to user-initiated fetches under your interpretation of RFC 9309 and the source site's own access policy; and
• your retrieval complies with applicable law, including copyright, computer-access, and data-protection regimes in your jurisdiction and the source site's jurisdiction.

Lyrenth retrieves API-submitted URLs at your direction, as your retrieval tool. We do not independently determine that you are authorized to access them.

Lyrenth operates two distinct URL-retrieval surfaces with different compliance postures.

Our background indexer visits URLs discovered from sitemaps, link graphs, partner submissions, and prior fetches. Because Lyrenth chooses what to fetch and when, our crawler is the actor under RFC 9309. The crawler:

• identifies itself with a consistent User-Agent containing "AIWebIndex";
• fetches and honors robots.txt for every origin before crawling any URL on that origin;
• refuses URLs matching a Disallow rule for our user-agent (RFC 9309 §6.1);
• raises its per-domain cooldown to honor declared Crawl-delay directives (RFC 9309 §6.2);
• caches parsed robots.txt for 24 hours per origin, limiting robots.txt fetches to approximately one per origin per day regardless of fleet size.

See /crawler-policy for the full operational disclosure.

When a customer calls our API with a specific URL, the customer is the actor: the customer chooses the URL and the timing and asks Lyrenth to act as its retrieval tool, in the same posture as user-initiated archive tools, link previewers, and browsers. Lyrenth does not, by default, enforce robots.txt on API-initiated fetches; the calling customer is responsible for that compliance under Section 6.

We reserve the right to:

• throttle or refuse API requests against any origin when our systems or the origin's behavior indicate that aggregate customer request rates are disrupting that origin, regardless of any individual customer's compliance posture;
• honor takedown or access-restriction requests from origin operators by adding their domains to a refusal list affecting all customers;
• suspend or terminate accounts whose usage patterns, in our reasonable judgment, evade robots.txt or related access restrictions in a manner that exposes Aleksma Ai, Inc. to legal or reputational harm.

Enterprise customers who require robots.txt enforcement on their API requests may request account-level activation at hello@lyrenth.com.

The Lyrenth crawler builds two logically distinct corpora from the public web: same crawler, same AIDocument output shape, different consent posture and downstream uses.

Every URL we crawl from the open web that is not disallowed by the source site's robots.txt, governed by the RFC 9309 compliance described in Section 7.1. Available to API customers in real time for per-URL retrieval.

The General Index is also available for enterprise corpus access and dataset licensing under separate written agreements. For corpus access, Lyrenth licenses its own database, compilation, and AIDocument transformation and provides access to the underlying publicly accessible content strictly on an “as is” basis: we make no warranty as to copyright or other third-party rights in that underlying content, and the customer is solely responsible for its own rights-clearance and legal compliance for its use, including any model-training use. Corpus customers, including AI labs, do not operate or direct our crawler; they access an independently maintained index.

A strict subset of the General Index covering domains whose verified owner has granted corpus rights under this Section (the “Verified Publisher Grant”).

The grant. By verifying a domain at /sites/add, the verifying owner (the “Publisher”) grants Aleksma Ai, Inc. a non-exclusive, worldwide, royalty-free, transferable, sublicensable license to crawl, retrieve, reproduce, store, cache, transform into AIDocuments and derived formats, distribute, publicly display in machine-readable form, and license the domain's canonical content, including the right to sublicense that content to AI labs and model companies for AI development, training, fine-tuning, evaluation, retrieval, and related uses. Lyrenth retains all licensing proceeds; there is no revenue share.

Consideration.In exchange, the Publisher receives the owner toolkit at no cost (dashboard, AI Readiness, verified-owner controls, change webhook) and the domain's canonical pages are served to agents reading through Lyrenth. This toolkit and representation, not a payment, are the consideration for the grant; a domain cannot be verified without accepting it.

Publisher warranties. The Publisher represents and warrants that (a) it owns or controls the verified domain; (b) it owns, or has rights sufficient to grant the license above in, the canonical content of the domain, excluding Third-Party Materials; and (c) the grant does not conflict with any agreement binding the Publisher. “Third-Party Materials” means content on the domain that the Publisher does not have the right to sublicense: for example, licensed agency photography, embedded third-party media, syndicated content, and user-submitted material not covered by the Publisher's own terms. The grant does not extend to Third-Party Materials, and the Publisher agrees to identify, exclude, or restrict crawling of paths containing material Third-Party Materials using the controls we provide, and to indemnify Lyrenth under Section 14 for breach of these warranties.

Consent ledger. The Publisher accepts the grant as part of these Terms at verification. We record the consent (who opted in, when, and from which IP address) in an append-only ledger. The ledger survives later removal, so a Publisher can verify and prove its historical consent state at any time. Ledger data is processed as described in our Privacy Policy.

Leaving the Verified Index. The Publisher may remove a domain from its settings at any time. Removal applies prospectively: the domain is excluded from future Verified Index deliveries and future licensing from the moment of removal, and we stop future crawling of the domain on request. Content already delivered to a licensee under consent valid at the time of delivery is not clawed back. After removal, the domain remains in the General Index on an “as is” basis unless the Publisher reserves AI/TDM rights or requests full removal.

Rights reservations. Independently of verification, any domain that declares a machine-readable reservation of text-and-data-mining or AI-training rights (for example via the TDM Reservation Protocol or a robots noai directive) is excluded from corpus licensing entirely. We honor such reservations worldwide.

Domains verified before this requirement took effect keep their prior state and may opt in from settings.

The General Index licenses our database, transformation, and access to publicly available content, with the customer carrying its own rights-clearance. The Verified Index is the consent-backed tier in which the Publisher has granted us underlying content rights (excluding Third-Party Materials), and for which we can warrant provenance and permitted-use rights to corpus licensees under separate written agreements. Reserved and removed content is excluded from both.

We respect intellectual property rights. If you believe content available through the Service infringes your copyright, notify us at hello@lyrenth.comwith: (a) identification of the copyrighted work; (b) the URL(s) of the allegedly infringing material in our index; (c) your contact information; (d) a statement that you have a good-faith belief the use is not authorized by the copyright owner, its agent, or the law; and (e) a statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on the owner's behalf.

Upon receipt of a valid notice we will expeditiously remove or disable access to the identified material in our index and refuse future crawling of it, and we will take reasonable steps to notify affected parties, who may respond with a substantiated objection.

We maintain a policy of terminating, in appropriate circumstances, accounts and verified domains that are repeat infringers.

Origin operators who simply want their content excluded from the Service do not need a copyright notice: robots.txt directives, AI/TDM reservations, and removal requests to hello@lyrenth.com are honored as described in Sections 7 and 8.

Our Privacy Policy at /privacy describes what we collect (account data, billing state via Stripe, request logs, consent-ledger records) and how we process personal data appearing in publicly accessible content we index, including how data subjects and site operators can request correction or removal. The Privacy Policy is part of these Terms.

The Lyrenth brand, platform, infrastructure, software, index, database compilation, and our implementation of the AIDocument format are owned by Aleksma Ai, Inc.. No rights are granted except as expressly stated in these Terms.

Website owners retain ownership of their own content. Lyrenth resolves publicly accessible pages into canonical AIDocument representations for AI consumption; we claim rights in our transformation and compilation, not in the underlying third-party content.

AIDocument responses you receive through the API may be used within your applications, workflows, and AI systems, subject to these Terms and to any rights of the underlying content owners, for which you remain responsible per Section 6 and Section 8.1. You may not resell, redistribute, or sublicense raw AIDocument responses as a standalone dataset or competing service without a separate written agreement.

If you send us feedback, suggestions, or ideas about the Service, you grant us a perpetual, irrevocable, royalty-free license to use them without restriction or compensation.

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not guarantee uninterrupted availability, AIDocument accuracy or completeness, compatibility with every website, or continuous operation of any feature. We make reasonable efforts to maintain reliability but provide no uptime SLA for self-serve plans unless a separate written agreement says otherwise. The Service may evolve, change, or discontinue features at any time.

We are not responsible for the accuracy, legality, availability, or reliability of content published by third-party websites. We surface publicly available content as published by site operators.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, ALEKSMA AI, INC. AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION, OR FOR RELIANCE ON AIDOCUMENT CONTENT WE RETURNED, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO LYRENTH IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) USD 100.

Some jurisdictions do not allow certain limitations; in those jurisdictions our liability is limited to the maximum extent permitted. Nothing in these Terms limits liability that cannot be limited by law, or non-waivable consumer rights in your jurisdiction.

You will defend, indemnify, and hold harmless Aleksma Ai, Inc.and its officers, directors, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Service or of content obtained through it; (b) URLs you submit and retrievals performed at your direction; (c) your breach of these Terms, including the warranties in Section 6; (d) for Publishers, breach of the warranties in Section 8.2, including claims by third parties whose rights are implicated by content you caused to be included in the Verified Index; or (e) your violation of applicable law or third-party rights.

We will promptly notify you of any such claim and may participate in the defense with our own counsel at our expense. You may not settle any claim in a manner that imposes obligations on us without our written consent.

Parts of the platform may be beta or experimental. Features may change rapidly and may contain interruptions, bugs, or incomplete functionality. Beta features are provided with no warranty of any kind and may be modified or withdrawn at any time.

We may suspend or terminate accounts that violate these Terms, create legal or security risk, or remain unpaid. Where practical, we will notify you and give you an opportunity to cure before termination, except where immediate action is required.

You may terminate your account at any time by contacting hello@lyrenth.com. Termination does not remove obligations that arose before it, including unpaid invoices, payment disputes, misuse investigations, or legal obligations that survive closure.

Sections 6, 8 (with respect to the prospective-only effect of removal and the consent ledger), 9, 11-14, and 16-19 survive termination.

You may not use the Service in violation of US export-control or sanctions laws, and you represent that you are not located in, or ordinarily resident in, a jurisdiction subject to comprehensive US sanctions and are not a sanctioned or restricted party.

These Terms are governed by the laws of the State of Delaware, USA, excluding its conflict-of-laws rules. Subject to Section 13's consumer-rights carve-out, all disputes arising from these Terms or the Service shall be resolved exclusively in the state or federal courts located in Delaware, and each party consents to their jurisdiction.

TO THE EXTENT PERMITTED BY LAW, EACH PARTY WAIVES ANY RIGHT TO A JURY TRIAL AND AGREES THAT DISPUTES WILL BE BROUGHT ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING.

If you are a consumer in a jurisdiction that grants you non-waivable rights to bring claims in your local courts or under your local law, those rights are unaffected.

Entire agreement. These Terms, the Privacy Policy, and any separate written agreements between you and us constitute the entire agreement regarding the Service and supersede prior discussions. In a conflict between these Terms and a separate signed agreement, the signed agreement controls.

Assignment. You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition, reorganization, or sale of assets.

Severability. If any provision is held unenforceable, it will be modified to the minimum extent necessary, and the remainder stays in effect.

No waiver. Failure to enforce a provision is not a waiver of it.

Force majeure. We are not liable for delay or failure caused by events beyond our reasonable control, including outages of upstream providers, network failures, acts of government, or natural events.

Notices. We may provide notices via email to your account address or through the dashboard. Legal notices to us go to hello@lyrenth.com and the registered address below.

We may modify these Terms periodically. Material changes will be communicated at least 30 days before taking effect, via email or dashboard notice. Continued use of the Service after updated Terms take effect constitutes acceptance. If you do not accept a material change, your remedy is to stop using the Service and, for Publishers, to remove verified domains before the change takes effect.
