380 endpoints you can pay for, per call

Multi-chain reads, contract state and deterministic compute over x402. No account, no API key, no subscription — your agent presents a payment and gets an answer. Every response carries its sources and its limitations, and an unreachable source is reported as unavailable, never as a zero.

How to call one

  1. POST the endpoint with your parameters. You get HTTP 402 and an accepts list.
  2. Sign a payment for one of those lanes and re-send with an X-PAYMENT header.
  3. You get the answer plus a settlement receipt. Bad parameters are refused before your payment is verified or settled — a malformed call costs you nothing.
