Api Endpoint

Find AI Agents by Skill

Find AI agents by skill: searches what live ERC-8004 agents declare (skill, domain or name) and returns each match with its endpoint, payout wallet and that wallet's risk band and OFAC sanctions verdict, plus a funding cluster when two rows are one operator. Optionally only agents that accept x402. 100 per page. Base. Free: GET /v1/search. Trial: /v1/trial.
