Before an AI agent trusts or pays a public API, inspect its public machine-readable evidence and x402 readiness. Submit a public HTTPS domain to check its agent card, OpenAPI, robots policy, and settlement-aware x402 signals, or submit a Base address for public onchain evidence. Returns a timestamped JSON report; not a security or compliance audit.

Verify whether a cited source supports an exact factual claim

Healthcare text de-identification engine (demo endpoint — SYNTHETIC/TEST DATA ONLY, never send real PHI; nothing is stored). Strips names, DOBs, member/claim IDs, phones, emails, addresses, SSNs; dates become a derived interval timeline (service-to-denial days, days-ago) so denial and timely-filing math survives de-identification. Returns scrubbed text + token map for local re-identification. Prod

Performs comprehensive URL health checks, measuring response time, status code, security headers, and TLS/SSL certificate validity. Route: GET /paid/health-check?url=https://example.com. Ideal for automated monitoring and endpoint auditing.

Password - CASA Cybersecurity Assessment - Consolidates evidence on secure communications, including certificate validity, hostname matching, protocol and cipher strength, forward secrecy, and TLS vulnerabilities. It determines whether the service uses a secure, authentic, and correctly configured transport channel.

Paragraph-cited semantic search over indexed SEC filings

SFtunes catalog for agents: index of public mixtapes and public Top 10 lists, or one item with liner notes and music-service links via ?id=<uuid> (tape) or ?id=top10-<handle> (a person's Top 10 + Side B).

Public-domain USDOT data.

Resolve a company name, website domain, registry number, LEI or VAT number to its official legal entity: registry, registry number, legal form, status, address, industry codes, size where published and LEI.

Classify text an AI agent is about to read for prompt injection: verdict (safe, suspicious, malicious), score 0-100, findings with matched spans; decodes hidden Unicode tags, HTML comments, CSS-hidden text and base64 before scanning.

Check whether a person or company appears on the SAM.gov federal exclusions (debarment) list. Query by name, UEI, or CAGE code. Returns exclusion details and an audit receipt.

Give this API up to 10 domain names and it tells you whether each has a registration record at the official registry. It uses RDAP, the structured replacement for WHOIS, so there is no free-text parsing. Each domain comes back as 'registered', 'unregistered', or 'indeterminate' when the registry has no RDAP for that ending. 'Unregistered' means no record was found, which usually means available -

Send up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per d
