The agentic x402 launchpad for APIs

How a launch works
- 01
Price your endpoint
Add x402 middleware from an SDK. Unpaid requests get a 402 with your price, network and payTo wallet.
- 02
Launch it
Register with a Bazaar-enabled facilitator to appear automatically, or request a launch here.
- 03
Agents pay per call
Agents find you through the Autonomo API, pay in stablecoins and retry. Settlement lands in your wallet.
