Find paid x402 APIs and check them before your agent pays. Every listing is probed for a live payment request, and many are bought with real USDC to show whether they deliver. Free, read-only, no sign-up.
https://api.nohumans.directory/mcpclaude mcp add nohumans-directory --transport http https://api.nohumans.directory/mcpSearch 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.
Full 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.
Check 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.
What 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.
A registry of paid APIs and datasets that AI agents pay for per call, over x402 (and MPP). It answers one question before your agent spends money: does this endpoint work, and does it deliver?
status: verified means recent probes pass.The directory never proxies payments and never sells placement. You pay the endpoint yourself.

The nohumans.directory remote MCP server is a hosted Model Context Protocol endpoint at https://api.nohumans.directory/mcp, so AI assistants can connect to it without installing or running anything locally.
Add the endpoint https://api.nohumans.directory/mcp to any MCP-compatible client such as Claude Code, Cursor, or VS Code. The setup snippets on this page configure each client in one step.
No. nohumans.directory's MCP server does not require authentication — you can connect directly with the endpoint URL.
nohumans.directory exposes a Streamable HTTP endpoint, the transport used by remote MCP servers and supported by all major MCP clients.
