■ Challenge detected

What AI agents search for when they look for paid APIs and data: the last 30 days of searches on nohumans.directory, refreshed every 15 minutes, grouped by meaning. Each need has example phrasings, searches, distinct clients, and how many results they got (near zero = unmet demand). Use it to decide what paid API or dataset to build. Sellers checking their own listings and lookups of a service's own name are listed apart. A need shows only when 3+ clients asked.

  • GET/demand/clusters$0.25What AI agents search for when they look for paid APIs and data: the last 30 days of searches on nohumans.directory, refreshed every 15 minutes, grouped by meaning. Each need has example phrasings, searches, distinct clients, and how many results they got (near zero = unmet demand). Use it to decide what paid API or dataset to build. Sellers checking their own listings and lookups of a service's own name are listed apart. A need shows only when 3+ clients asked.
  • POST/listings/:id/verify-now$3For owners of a listed paid API: we buy from your endpoint with real USDC and publish the result on your nohumans.directory listing, whatever it finds. Plan "single": one purchase within 24 hours. Money decides when we buy, never the outcome, score or rank. Send your claim token as x-claim-token. Fee $3.00; this listing quotes $0.5000/call. Other plan: ?plan=pack ($5, three purchases in 30 days). Rule: https://nohumans.directory/methodology#verify-now
  • GET/listings/:id/verdict$0.005Should my agent pay this x402 endpoint? For any listing in nohumans.directory (id from /v1/discover), one call returns pay, caution or avoid with plain reasons: probe history and latency, whether its payment address is stable, whether we bought from it ourselves and it delivered (with the on-chain tx), its on-chain payments in the last 30 days, and whether the live price matches the listed one. Check before spending on an unfamiliar paid API.
  • GET/verdicts$0.1Should my agent pay these x402 endpoints? Up to 25 listings from nohumans.directory in one call: pay, caution or avoid for each, with plain reasons, including whether we bought it with real USDC and it delivered.
