Tokenizes each claim and its supplied evidence, removes a small declared English stop-word list, and reports the fraction of unique claim tokens present in evidence. Coverage below a supplied threshold is flagged. This is lexical grounding screening only: overlap does not prove truth, low overlap does not prove hallucination, and the service does not retrieve or validate evidence.

Check an x402 endpoint BEFORE paying it. Makes one unpaid request (never sends money), decodes the 402 terms, and verifies: the asset is a real USD stablecoin on that network, the price in USD vs your max_price_usd cap (default $0.50), payTo is a sane address (and matches expected_pay_to if given), HTTPS and certificate validity, redirects, and domain age. Returns safe_to_pay, a risk level, findin

Use before spending tokens, money or crawler capacity fetching an unfamiliar web resource. Resolves redirects (manually, bounded, re-validated per hop) and returns deterministic HTTP/resource facts — final URL, status, content type and length, response time, a bounded HTML title/canonical peek, and a lightweight generic-bot robots.txt indication — so an agent can decide whether a normal web fetch
