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 mix subscriptions with micropayments?

Baseline monthly plan + metered per-call/per-token gated by a402; settle instantly, no pre-funding.

How do I earn yield while processing payments?

Route balances to Agentic Treasury where yield streams in real time, offsetting or beating fees ("negative-fee").

Beep is not a bank, financial institution or a digital asset custodian.

Beep is a financial technology platform that enables eligible businesses to establish a self-custodied digital asset account and conduct transactions using stablecoins through the account.

Balance information denominated in fiat currency is for informational purposes only.

Stablecoins function as claims on the stablecoin issuer for a fixed amount of underlying fiat currency.

Beep is not a stablecoin issuer, does not make any promise (and does not have any obligation) to redeem stablecoins.

Beep does not hold any balance on behalf of its business customers and does not pay interest on digital asset balances.

Eligible business customers may earn rewards from beep based on their use of the beep services and the self-custodied digital asset account.

Yield is variable and not guaranteed. DeFi carries smart-contract and protocol risks. Review docs, your jurisdiction’s regulations before using Beep. Not investment advice.
