2s bronze

2s.io

“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).

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of 2s.io controls every word below.

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.

What its catalog declares

From the ARD catalog this host publishes at /.well-known/ai-catalog.json. The operator controls every entry; agenttru.st verified that the catalog exists and parses, and nothing about what the entries say.
