Machine-to-Machine Payments

Let agents pay for APIs and compute per call.

A stablecoin wallet per agent that pays over x402 and MPP. Fund it by card, spend a few cents at a time, and cash out to a bank.

What agents buy per call

Inference and compute

Rent GPU compute and model access by the request, with no account to open.

Search and scraping APIs

Pay for each search, crawl, or scrape at the moment the agent runs it.

Research and market data

Buy data a few cents at a time from 40,000+ resources over x402 and MPP.

Agent Wallets

A wallet per agent, limits onchain

  • Non-custodial smart wallets

    Keys stay separate from funds. Each agent gets its own wallet.

  • Guardrails at the network layer

    Spend limits run onchain, so a compromised app cannot pass them.

Onramps

Fund the agent by card

  • Card in, USDC out

    The user tops up the agent inside your app, under your brand.

  • Cash out to a bank

    Offramp USDC to a bank account when the job is done.

Pay per call in a few lines of code

Get started

  1. Deploy a wallet for your agent

  2. The user buys USDC by card, delivered to the agent's wallet

  3. The API names its price; the wallet signs and the call goes through

  4. USDC settles onchain and the receipt rides back on the response

Frequently Asked Questions

Two open protocols that let an API charge per call over HTTP. The API answers a request with 402 Payment Required and its price, the agent's wallet signs a stablecoin payment, and the call goes through once it settles. A Crossmint agent wallet pays both x402 and MPP (Machine Payment Protocol) endpoints, in USDC, within the limits you set.
