Unmeasured means there is not enough evidence to decide. How these checks work
Start using nohumans.directory
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

Search paid x402 APIs and datasets by need. Ranked: verified first, then probe score, then price. Each result carries what you choose on: status, score (0..1), evidence_tier, paid_verified (we bought it with real USDC and it delivered), latest_purchase_delivered (false = our most recent paid purchase took real USDC and did not deliver: do not pay it), has_sample (a cheap preview exists), price. Relevance comes from the query text; a specific need in plain words matches best. Zero results means nothing listed matches. Results are dated evidence, not guarantees. Returns a summary per listing; detail='full' returns every field. Free, read-only.
DiscoveredFull record for one listing id: request and response schemas, sample_query, observed 402 terms (network, payTo, scheme, x402 version), reputation detail, and paid_verification (our latest real USDC purchase, with its settlement tx where proven). Useful before paying: it shows the exact request shape and current reliability. Every timestamp has an _iso twin; on-chain counts describe the seller's wallet, usually shared by several listings, not this endpoint. Free, read-only.
DiscoveredCheck an endpoint URL you already hold before paying it. Returns match 'active' with the listing's full record, 'delisted' (listed here, later removed), or 'unknown' (never checked here; absence is not a verdict either way). The record is dated evidence, not a safety rating. Free, read-only.
DiscoveredWhat agents searched this directory for, for deciding which x402 service to build or list. Terms ranked by how many distinct days they were asked, each with catalogue_top: the listings our own search already returns for it. A term being asked does not mean nothing serves it. The window ends live, rebuilt hourly (no delay since 2026-11-08; delay_hours and window_ends_at in the response say so); test traffic, sellers searching their own listings and identifying terms are excluded; floor: a term appears once at least 1 distinct non-seller client IP asked it. Client counts are IP ceilings, never buyer counts. Paged: limit (default 25), offset, next_offset. Free, read-only.
