x402 payment protocol support for agent-to-agent transactions

[up2itnow0822]

Paystack's MCP server handles human-to-merchant payments through agents. But what about agent-to-agent payments where there's no human in the loop?

The gap:

Your current MCP server lets an agent initiate a Paystack checkout on behalf of a user. That works for e-commerce. But the growing use case is agents paying other agents for API calls, data, compute - autonomously and without a human credit card.

What x402 solves:

x402 is the HTTP payment protocol (started by Coinbase, now adopted by AWS and others). When an API returns HTTP 402, the calling agent:

1. Reads payment terms from the response header
2. Signs a USDC payment from its own wallet
3. Retries with payment proof attached

No checkout page. No credit card. No human.

Integration proposal:

We maintain Agent Wallet SDK and AgentPay MCP - open-source x402 payment infrastructure for AI agents.

A Paystack x402 bridge would:

• Let Paystack merchants accept x402 agent payments alongside traditional checkout
• Settlement in USDC on Base, converted to local currency via Paystack's existing rails
• Open African enterprise market to autonomous agent commerce

We'd be happy to build a reference implementation. Interested?
