What is a402 and how do I integrate it?

a402 extends HTTP-402 so your server can challenge a paid request, verify a machine payment, then release. Drop middleware, price endpoints, and use SDK pay()/verify(). Flow: request → 402 → pay → verify → release.

How do I add stablecoin payments to my app (Typescript/Python/Go)?

Use Beep’s SDK or HTTP APIs to auto-handle 402: on challenge, pay, verify receipt, retry; returns JSON receipt.

How do I monetize MCP tools per call?

Wrap tool routes with 402 middleware; issue challenge; on receipt verify → release; optional dual-hop split to platform/provider.

How do I earn yield while processing payments?
