What it can do
| Tool | What it says it does |
|---|---|
availability | URL → a signed uptime/status probe: up/down, HTTP status + class, reachability reason, final URL after redirects, and a measured responseMs — wrapped in an offline-verifiable provenance receipt that makes "it was up/down at T" provable SLA evidence. Deterministic verdict (responseMs is telemetry… |
batch | List of URLs (≤20) → clean content for each + ONE signed receipt committing to a MERKLE ROOT over every page's contentHash. Tamper-evident multi-page snapshot with per-page membership proofs (selective disclosure). Deterministic (no LLM): same URL set + same source bytes ⇒ byte-identical root +… |
diff | URL + prior content-hash (or prior text) -> refetch, deterministic change-proof: changed? + a NEW signed receipt binding fromHash->toHash. Stateless; receipts chain into a tamper-evident audit trail of a page's evolution. Keyless x402, Base mainnet USDC. — $0.006/call |
dns | Domain → a SIGNED, timestamped DNS snapshot (A, AAAA, MX, NS, TXT, CNAME, SOA), normalised + sorted into a byte-stable record set with an offline-verifiable provenance receipt — proving exactly what the zone resolved to at that moment. Keyless, no LLM, no signup. (Normalisation is deterministic… |
extract | TYPED structured extract for autonomous agents — URL + schema → a clean, type-safe JSON record. Where /buy/fetch returns page TEXT (and ?extract= returns string-only fields), THIS returns the schema-conformant object an LLM/RAG/trading pipeline actually consumes: pass… |
feed | RSS/Atom feed URL → a SIGNED, normalized item list [{title,link,published,summary}] unified across RSS 2.0/RDF + Atom 1.0: CDATA unwrapped, HTML stripped, entities decoded, dates → ISO-8601 (publishedRaw kept verbatim, never fabricated). Deterministic — same feed bytes ⇒ byte-identical items; no… |
fetch | VERIFIABLE keyless web-read for autonomous agents. Every result ships a cryptographically SIGNED provenance receipt (EIP-191 over sha256(text)+url+status+time) — the wedge a free scraper structurally CANNOT match: Jina r.jina.ai is free+keyless too, but its bytes are HEARSAY (no proof of… |
headers | URL → a deterministic HTTP security-headers audit (HSTS, CSP, X-Frame, X-Content-Type, Referrer-Policy, Permissions-Policy + more) with a letter grade and concrete findings, wrapped in a signed, offline-verifiable provenance receipt. Keyless, no LLM, no signup. — $0.005/call |
links | URL → a SIGNED outbound/internal link graph: every <a href> as an absolute URL + anchor text, classified internal vs external against the page origin, grouped by origin with a third-party-origin histogram (privacy-audit) and same/cross-origin counts (SEO). Deterministic — same page bytes ⇒… |
markdown | URL → clean, LLM-ready markdown (boilerplate/nav/ads stripped, headings + lists + links preserved) with a signed provenance receipt pinning the markdown to its source — the RAG-ingest primitive. Deterministic (no LLM): same URL + same source bytes ⇒ byte-identical markdown. — $0.005/call |
metadata | URL → one typed, SIGNED metadata record (JSON-LD + OpenGraph + Twitter-card + standard <meta> + canonical + title), by source. Deterministic, keyless, no LLM — the social-card/SEO/schema.org record an agent can PROVE. — $0.006/call |
notarize | Notarize any content (inline ?content= or a fetched ?url=) into a signed, offline-verifiable provenance receipt — sha256 contentHash + witnessed timestamp, attested by Mercury's pinned key. Deterministic, keyless, no LLM. The signed receipt is the product: it witnesses that these exact bytes… |
readability | URL → a clean ARTICLE record { title, byline, publishedAt, article text } with boilerplate (nav/header/footer/sidebar/ads/share-bars/comment-forms) stripped via deterministic DOM density heuristics, plus a signed provenance receipt pinning the cleaned article to its source — the clean-citation… |
redirect | URL → a SIGNED redirect/canonical resolution: the full hop chain [{url,status}] from the link you have to where it ACTUALLY lands, the final resolved URL + status, the page's <link rel=canonical>, hop count, cross-origin flag and distinct origins traversed (affiliate-cloak / link-safety signal)… |
robots | Domain → signed, timestamped per-AI-crawler allow/block audit from robots.txt + llms.txt + ai.txt (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bytespider, …). Deterministic, no LLM. EU-AI-Act / TDM opt-out evidence: the signed verdict proves the crawler policy as it stood at fetch time. —… |
sitemap | Domain/URL → a SIGNED snapshot of the site's PUBLISHED sitemap: discovers the sitemap via robots.txt Sitemap: lines then /sitemap.xml fallback, parses <urlset> + <sitemapindex> (follows up to 5 child sitemaps), returns a deduped, bounded (≤2000) URL inventory with lastmod/changefreq/priority. The… |
table | URL in → the page's main HTML <table>(s) parsed into typed, header-keyed rows (JSON) + clean RFC-4180 CSV, with a signed provenance receipt over the exact extracted grid. Deterministic, keyless, no LLM — x402, USDC on Base mainnet. — $0.006/call |
validate | URL (a JSON/API endpoint) + a JSON Schema in → a deterministic pass/fail with per-field errors (missing/wrong-type/enum/range/pattern), plus a signed provenance receipt binding the verdict to the exact response bytes AND the exact schema. Deterministic, keyless, no LLM — x402, USDC on Base… |
