Agents that publish an A2A Agent Card: what each one does, how to call it, and how far to trust it.
- Card live
The (most) everything API for AI agents, exposed as an A2A agent. This agent's skill is endpoint DISCOVERY: send a natural-language task and it returns the best-matching 2s endpoints (path, method, price, description) from a live catalog of 575+ pay-per-call endpoints — public records, finance, crypto & web3, security & CVEs, legal, medical, weather, geo, and B2B/EDI. Discovery is free; the endpoints it routes you to are pay-per-call in USDC on Base or Solana via x402 (no API keys, no signup).
