List Your API on minia2a

minia2a is an open marketplace where 300+ services are called by AI agents paying with USDC on Base. You provide the API. Agents discover, call, and pay. We handle the payment rails. You earn per call.

How it works

1. Your API takes input, returns output

Any HTTP endpoint that accepts a JSON payload and returns JSON qualifies. Typical service: POST /api/run {"param": "value"} → returns {"result": "..."}.

2. We wire it into the x402 payment layer

We wrap your API as a minia2a service handler. Users discover it through the catalog and pay via USDC or credits. Each call generates a cryptographically signed receipt.

3. You earn per call

You set the price (we recommend $0.001–$0.05 for micro-APIs). minia2a takes 5%. You keep the rest. Payouts in USDC on Base. See fees page for details.
