Terms of Service

Draft — pending legal review. Not yet in effect. This text is a working draft prepared for the operator's legal counsel. It is not legal advice and is not a binding agreement. Bracketed [PLACEHOLDER] items must be completed and the whole document reviewed by a qualified attorney before it is published or relied upon.

Effective date: [PLACEHOLDER: effective date — not in effect until set]. Last updated: [PLACEHOLDER: draft date].

1. Acceptance of these terms

These Terms of Service ("Terms") govern your access to and use of the Sigildex API, MCP server, command-line interface, website, and related services (collectively, the "Service"), operated by [PLACEHOLDER: legal entity name] ("Sigildex", "we", "us"). By accessing or using the Service — including by sending any request to the API — you agree to these Terms. If you are using the Service on behalf of an organization, you represent that you are authorized to bind that organization. If you do not agree, do not use the Service.

2. Description of the Service

Sigildex is a headless skill-discovery and verification API for AI agents. It indexes publicly available SKILL.md content and metadata from public source platforms (such as GitHub and a frozen ClawHub snapshot), computes trust and safety signals, and returns ranked discovery, inspection, and verification results that link to the original sources. There are no user accounts; identity is the calling wallet (for paid requests) plus IP address (for the free tier and rate limiting).

Sigildex does not host, sell, or redistribute the skills themselves. Indexed content remains the property of its original authors, and any download, installation, or use of a skill happens at its original source under that source's own license and terms. The Service is provided for discovery and evaluation; it is not a software distribution channel.

3. Free tier and pay-per-query

• The first 50 discovery workflows per day per IP address are free. /verify is always free.
• Beyond the free tier, each discovery workflow costs $0.002 USDC, paid via the x402 protocol on the Base network (chain eip155:8453). A workflow is one /discover call plus up to five free /inspect calls using the returned query_id.
• Payments are settled through a third-party facilitator (Coinbase Developer Platform). Sigildex is non-custodial and does not hold your funds beyond per-request settlement. You are responsible for your wallet, your keys, and any network/gas costs.
• Pricing, free-tier limits, and supported payment methods may change; changes apply prospectively and will be reflected on the Service and in its published descriptors.
• Except as required by law, paid requests are non-refundable. On-chain transactions are irreversible and outside our control.

4. Acceptable use

You agree not to, and not to permit your agents or systems to:

• use the Service for any unlawful purpose or in violation of any applicable law, regulation, or third-party right;
• abuse, overload, disrupt, or impair the Service, or attempt to circumvent rate limits, the free-tier cap, payment, or any access control;
• scrape, harvest, or systematically extract the index or results in order to mirror, republish, resell, or build a competing or substitute corpus of the indexed content or our derived signals;
• probe, scan, or test the vulnerability of the Service, or breach or circumvent its security or authentication, except via our published vulnerability-reporting channel;
• misrepresent the origin of requests, or use another party's wallet or identifiers without authorization;
• use the Service to discover, distribute, or facilitate malware or other materials intended to cause harm, or in any way that infringes intellectual-property or privacy rights.

We may rate-limit, suspend, or block access (including by IP or wallet) to protect the Service or other users. Responsible security research conducted in good faith through our reporting channel is welcome — see reporting a vulnerability.

5. Safety verdicts are advisory — review before you install

Sigildex's safety verdicts and trust signals are advisory signals, not guarantees. They are produced by automated analysis and may be incomplete, out of date, or wrong. Critically, they analyze only the SKILL.md instructions and metadata — they do not evaluate bundled scripts, dependencies, transitive packages, runtime behavior, or anything that happens at install time or execution time.

A favorable verdict is not a certification that a skill is safe, fit for purpose, or free of malicious or harmful behavior, and an unfavorable verdict is not a definitive judgment about its author. You — and any agent acting on your behalf — are solely responsible for independently reviewing, vetting, and testing any skill before installing, executing, or relying on it. You assume all risk arising from discovering, selecting, installing, or using any skill surfaced by the Service. Do not rely on Sigildex verdicts as your only safety control.

6. Intellectual property

The Service itself — including the Sigildex name and marks, the website, the API design, and our computed rankings, trust, and safety signals — is owned by [PLACEHOLDER: legal entity name] or its licensors and is protected by applicable law. The open-source Sigildex software is licensed under MIT; nothing in these Terms grants you rights in our names, marks, or hosted Service beyond the limited right to use the Service as intended.

Indexed content is not ours. SKILL.md files and related metadata surfaced by the Service are the property of their respective authors and are made available by those authors on public platforms under their own licenses. Your rights to use any indexed skill are governed solely by that skill's own license and the terms of the platform hosting it, not by these Terms. If you are a rights holder and believe indexed content infringes your rights, see our DMCA / content takedown policy.

7. No warranty

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. WE DO NOT WARRANT THE ACCURACY, COMPLETENESS, RELEVANCE, OR SAFETY OF ANY DISCOVERY RESULT, RANKING, METADATA, OR SAFETY VERDICT, OR OF ANY THIRD-PARTY SKILL OR SOURCE. YOUR USE OF THE SERVICE AND OF ANY SKILL YOU DISCOVER THROUGH IT IS AT YOUR OWN RISK. [PLACEHOLDER: confirm jurisdiction-specific warranty disclaimers and any non-excludable consumer guarantees with counsel.]

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SIGILDEX AND ITS OPERATORS, OFFICERS, AND CONTRIBUTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR FUNDS, ARISING OUT OF OR RELATING TO THE SERVICE OR TO ANY SKILL DISCOVERED THROUGH IT, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU PAID US FOR THE SERVICE IN THE [PLACEHOLDER: liability lookback period, e.g. 3 months] BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) [PLACEHOLDER: nominal liability cap, e.g. US$100]. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. [PLACEHOLDER: confirm liability framing with counsel.]

9. Indemnification

You agree to indemnify, defend, and hold harmless Sigildex and its operators and contributors from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or related to your use of the Service, your violation of these Terms, your violation of any law or third-party right, or your installation or use of any skill discovered through the Service.

10. Termination

You may stop using the Service at any time. We may suspend, restrict, or terminate your access to the Service at any time, with or without notice, including for any violation of these Terms or to protect the Service or other users. Sections that by their nature should survive termination — including intellectual property, no-warranty, limitation of liability, indemnification, and governing law — survive.

11. Changes to the Service and these Terms

We may modify or discontinue the Service, or update these Terms, at any time. Material changes to these Terms will be reflected by updating the "Last updated" date above and, where appropriate, by additional notice. Continued use of the Service after an update constitutes acceptance of the revised Terms.

12. Governing law and disputes

These Terms are governed by the laws of [PLACEHOLDER: governing-law jurisdiction], without regard to its conflict-of-laws rules. The parties submit to the exclusive jurisdiction of the courts located in [PLACEHOLDER: venue / dispute-resolution forum] for any dispute arising out of or relating to these Terms or the Service. [PLACEHOLDER: confirm whether arbitration, class-action waiver, or other dispute-resolution mechanism applies, with counsel.]
