MugglePay PartnersAgent Merchant API
Your AI agent opens the merchant account, invoices, and gets paid to your own wallet. No browser, no email.
Sign once. Your agent signs a server-issued challenge with its own wallet key. The key never leaves your runtime.
Merchant ready. One signature creates (or reopens) the merchant. Settlement is locked to Base USDC at the signing address — self-custody; we never hold your funds.
Scoped credential. A fresh signature issues an Orders-only API key. It can invoice and read payments; it can never touch settings, admin, or where funds go.
Invoice & verify. Create idempotent invoices, share the payment link, poll to payout_completed — then verify the payout on-chain yourself.
Credential issuance is invite-gated during alpha. Your agent requests access through the API itself and polls until approved — the whole loop is machine-driven; a human only clicks approve on our side.
Alpha scope: EVM EOA wallets only, settling USDC on Base. Solana and Stellar wallets can onboard and receive, but the agent credential loop is EVM-first for now. Contract wallets and passkeys are not supported.
Why MugglePay
- One signature, no forms. The wallet is the account — no email, no KYC form, no browser ceremony.
- Self-custody settlement. USDC lands at your own address on Base. We never hold your funds, and the payout address can't be changed by an API call.
- Least privilege by design. Agents get Orders-only keys: they can invoice and read payments — never admin, settings, or where money goes.
- Independently verifiable. Every payout is an on-chain transaction your agent can check itself, not a dashboard number you have to trust.
- Machine-first. The whole contract lives in /llms.txt: idempotent endpoints, single-use signed challenges, poll-to-terminal state.
About MugglePay. MugglePay is a stablecoin payment network for people and AI agents. Merchants accept USDC across chains — Base, Stellar, Solana and more — and settle non-custodially to their own wallets, with cross-chain payments typically completing in about 20 seconds. The stack covers checkout (pay any invoice from any chain), a cross-chain USDC settlement API, point-of-sale tools for real-world merchants, and this Agent Merchant API — merchant onboarding built for AI agents, end to end, with one wallet signature.
