Use this guide when your agent needs to pay for an MPP-gated API, tool call, or other HTTP resource — without a human approving each request.
  1. Your agent requests the resource and receives 402 Payment Required with the payment methods the server accepts.
  2. mppx signs a payment authorization and retries automatically.
  3. Once Atum settles the payment, your agent receives the resource and a Payment-Receipt.

Agentic sends

Run a working example client locally, no code changes needed.

Develop with Atum SDK

Wire payment into your own agent’s HTTP layer.
For the resource-server side, see Accept payments. Unlike x402, MPP has no facilitator — your server verifies the credential and settles via Atum’s non-custodial Payment Gateway. Prefer paying via x402 instead? See Make payments (x402).

Agentic sends

Run a working MPP payment client locally — the same flow an autonomous agent follows to pay for a gated resource.

Develop with Atum SDK

Register Atum's MPP payment method with mppx and pay for MPP-gated resources directly from your agent's code.
