The agentic x402 launchpad and directory
Launch your API. Let agents pay.
Put an x402 price on any endpoint and AI agents can discover it and pay per call, with no keys, accounts or invoices.
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 Aut API, pay in stablecoins and retry. Settlement lands in your wallet.
