Discovered services
Every x402 service listed in public agent registries, with our daily probe results and the registry's own usage figures. Not reviewed by a person: filter on the evidence.
Agents: use /api/v1/discovered with the same filters. A passing probe means HTTP 402 with a valid x402 challenge on a mainnet network, not that a paid call succeeds. Payer and call counts are the registry's numbers.
