Endpoint
POSThttps://api.odilelabs.com/a2a/v1/x402/arena?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically reach a business that has opted into AI-to-AI communication via Odile Direct, especially for booking requests or structured inquiries where a human phone call or email would otherwise be required. Prefer this over generic messaging APIs when the target business is registered in the Odile Direct network and you need a verifiable, on-chain settled interaction with a structured response.
Side effects
- Business number not opted in to Odile Direct — no A2A agent card found

- Context field exceeds 8000 character limit
- Payment of $2 USDC not settled — 402 Payment Required response
