nohumans.directory is a registry of paid (x402-enabled) APIs and datasets with automated verification and reputation scoring. Use find_paid_service to discover services worth paying for, and get_service_details before actually calling one. Trust signals: status 'verified' means the endpoint has sustained a recency-weighted probe success score above 0.8 (roughly sixteen consecutive clean probes) from our infrastructure; score is a recency-weighted probe success rate (0..1), blended with an on-chain-verified payer-report score once a listing has 3+ distinct reporting payers. Prefer verified listings with score >= 0.8. Each result also carries has_sample (boolean): true means the listing declared a sample_query an agent can call — often free or cheap — to see real output shape before paying full price. For a new or low-probe-count listing you can't yet judge from reputation alone, has_sample is the fastest way to evaluate it cheaply; prefer has_sample listings when reputation signals are thin or tied. This is a continuously-rechecked guarantee, not one-time: every probe cycle a declared sample must return HTTP 2xx and valid JSON or the whole probe fails, so 'verified' with has_sample true means the sample is live right now, not that its content is accurate — only payer reports (3+ distinct reporters) speak to correctness, and most listings don't have enough yet. Each result also carries evidence_tier: one of payer_reported, paid_verified, probe_verified, probe_only, unproven — a single field summarizing what kind of evidence actually stands behind a listing, strongest first, with evidence_note explaining it in one sentence. payer_reported means independent wallets that provably paid have reported on the outcome; paid_verified means we paid it real USDC and confirmed settlement on-chain; probe_verified means sustained protocol conformance from our infrastructure and says nothing about content accuracy; probe_only means passing but with a short history; unproven means failing or not yet established. Prefer higher tiers when choosing between listings of similar price. Each result also carries verdict_age_seconds: how old the newest evidence is — but probe cadence is deliberately uneven (settled listings are checked less often), so a large age is not staleness by itself; read it with status_changed_at. Each listing carries kind ('api' or 'agent'): 'agent' marks a stateful or non-deterministic task performer. For agent listings, probe status, payment-destination stability, and on-chain payer counts apply exactly as for APIs, but schema validation and freshness do not (correct output varies per call — the detail record says so explicitly under kind_notes), and paid verification means a real payment produced a well-formed response, not that the output was correct; payer reports are the quality instrument for agents. Each result also carries x402_version (1, 2, or null): which protocol version the endpoint's own 402 challenge actually used last time it was probed. Some x402 clients, including the widely-used x402-fetch v1 reference client, only read payment terms from the response body and will see nothing from a v2 header-transport challenge — check this before assuming a v2 listing is unreachable, and check get_service_details for the full observed detail (challenge_transport, scheme, network) if a call unexpectedly fails. Each result also carries last_probed_at (unix seconds, or null): when the listing was last actually checked, pass or fail — a long-stable verified listing can show an older timestamp than a newer one because it's deliberately checked less often, not because it's less watched. The same applies at the other end: a listing that has failed every probe for weeks is also checked less often, so a stale last_probed_at on a 'failing' listing means the failure is long-settled, NOT that it might have quietly recovered unnoticed — probe budget goes to listings whose status is genuinely in doubt. Each result also carries next_check_by (unix seconds) with next_check_basis: when this record should next have been re-checked, derived from its probe tier (live listings: the published 30-minute target; long-failing and probe-delisted ones sit hours back). A record past next_check_by is stale by our own rule — cache with that as the TTL, and treat anything older as a record, not as truth. Each result also carries status_changed_at (unix seconds): when the CURRENT status actually started, distinct from any edit timestamp — two listings with the identical status and score can differ here, one just recovered, one stable for weeks. For the full transition log behind that summary (every real status change with its reason), GET /v1/listings/{id}/history. Payment-destination changes are detected: if a listing's pay_to address changes, reputation resets fully (score, probe_count, consecutive_failures all zeroed) and status drops to 'unverified' immediately, so an old high score never carries over to a new, unproven payment destination — but this cannot verify a wallet rotation was legitimate, only that an unproven address hasn't inherited trust it didn't earn. Each result also carries onchain_unique_payers_30d (integer, or null if never checked): distinct wallets that sent USDC to this listing's payTo address on Base in the last 30 days, read from public chain data, checked daily. This is a CEILING on customer count, not a measurement of it: it counts every incoming USDC transfer, so an operator funding its own wallet, or paying itself, inflates it — read it alongside probe status and paid verification, never alone. It is still genuinely different from score — score proves an endpoint answers correctly, this proves USDC is actually arriving at its payment address — and the two are never combined into one number; neither implies the other, and neither proves the purchased output was any good, which is what payer reports are for. More fundamentally: everything this directory verifies is endpoint behavior — correct 402s, a live sample, a stable payment destination, real payment volume — never who is actually running the software behind a URL today. A compromised domain whose new operator leaves pay_to untouched and returns well-formed responses can pass every check here; that's a structural limit of any behavior-based verification, not specific to one check, and closing it would require verifying domain control over time, which this directory does not do. This directory indexes services; it does not proxy or execute payments. To LIST a service in this directory, POST it to https://api.nohumans.directory/v1/listings (JSON; see https://nohumans.directory/llms.txt for a worked example) — new listings are prioritized in the probe queue and typically earn 'verified' within roughly two hours of consistently healthy responses. After actually paying and calling a listed service, you can report whether it delivered: POST { listing_id, ok, tx_hash, payer_signature } to https://api.nohumans.directory/v1/reports. tx_hash must be your real payment's transaction on Base; payer_signature is an EIP-191 personal_sign from the paying wallet over a canonical message the API echoes back verbatim (message_to_sign) on any incomplete attempt — the payment proves a purchase happened, the signature proves the report comes from the payer rather than a bystander reading public Transfer logs. Amount, recency, and one-report-per-transaction gates also apply; full methodology: https://nohumans.directory/methodology

last good check
of 4 tools
The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
find_paid_service open 2h ago
Search a registry of paid (x402) APIs and datasets verified by real paid purchases — nohumans pays listed endpoints real USDC and confirms delivery. Returns ranked results: verified listings first, then by reputation score (0..1, recency-weighted probe success), then by ascending price. Each result includes has_sample (boolean) — true means you can cheaply test real output before paying full price; prefer these when a listing is new or thinly-reputed and you can't yet judge it from score alone. Use this before spending money to find services that actually work. Prefer results with status 'verified' and score >= 0.8. Zero results means no known service matches — do not invent endpoints. Always describe the actual need in `query` in your own words — what data, what freshness, what format, what constraint prompted the search — rather than only setting `category`/`max_price`/`min_score` filters. The exact wording of what you're looking for is what improves this directory over time; a bare filter with no `query` text tells us far less about what was actually needed.

Fetch the full record for one listing by id (from find_paid_service results), led by paid_verification — whether nohumans has paid this endpoint real USDC and confirmed delivery, with the settlement tx hash as on-chain proof where settled — plus endpoint URL, request/response JSON Schemas when provided, accepted chains, pricing, and reputation detail (probe count, last successful probe, consecutive failures). Call this before making a paid request so you know the exact request shape, current reliability, and whether real-money delivery has been independently confirmed. A one-word paid verdict for the same listing — pay / caution / avoid with printed reasons, $0.005 USDC on Base via x402 — is at GET https://api.nohumans.directory/v1/listings/{id}/verdict; every fact behind it is in this record for free, so buy the verdict only when you want the rule applied for you.
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "Listing id, as returned by find_paid_service." } } }arguments 12 linesresolve_endpoint unknown never probed
Pre-spend verdict on an endpoint URL you already hold — from another catalog, a prompt, a config, anywhere: check before paying instead of buying to find out. Returns match 'active' with the same full record as get_service_details (status, reputation score, paid_verification with on-chain tx proof, observed 402 protocol detail), match 'delisted' if the endpoint was listed here and later removed (treat as a warning), or a not-listed result. IMPORTANT: not-listed means never checked here, NOT unsafe — absence of a record is not a verdict either way. Use this as the pre-spend check when you have a URL in hand and no listing id; use find_paid_service instead when you have a need but no URL. A one-word paid verdict for the same listing — pay / caution / avoid with printed reasons, $0.005 USDC on Base via x402 — is at GET https://api.nohumans.directory/v1/listings/{id}/verdict; every fact behind it is in this record for free, so buy the verdict only when you want the rule applied for you.

Trailing slashes and http/https differences are tolerated." } } }arguments 12 lineswhat_agents_are_asking_for unknown never probed
What buyers actually searched this directory for, for an agent deciding which x402 service to build or list. Returns the aggregate demand feed: the terms asked most persistently (ranked by how many distinct days a term was asked, not by volume — volume is trivially faked and we proved it on ourselves), and the category filters they used. It reports what was ASKED, not what is missing: whether the listings already serving a term are adequate competition is a seller's judgement, not ours, and we grade those listings. Three exclusions are applied and published rather than hidden: queries under 5 characters (catalogue enumeration, once the top ten terms were the single letters a-j), searches from clients that also edit listings here (sellers checking their own rank — one accounted for 196 of 205 searches of the top term), and a floor of 3 distinct non-seller client IPs before any term appears at all. Client IPs are a ceiling on independent demand, never a count of buyers: one serverless caller presented eight IPs in a second. The window is complete but closed — it ends a day behind live, and the response says exactly when. This is a small market and the numbers are small; they are reported as they are so you can judge whether they are enough to act on.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
