What happens when AI buys from you, not humans. Accept Arispay and know your AI customer is funded and within its limits.
Arispay is payment infrastructure for agentic commerce — software that lets AI agents pay merchants online under developer-controlled guardrails: spend limits, delegated custody via Coinbase CDP, and signed receipts. x402 settlement is live on Base mainnet (USDC and EURC); card and bank rails are in development.
When an AI agent is the one placing the order, the payment layer has to answer for it — who authorized the spend, under what limit, with what proof. Arispay is that layer.
TravelWhen an agent books the flight, the cab, and the hotel, every payment clears spend limits enforced server-side before it signs — per-transaction, daily, and monthly — with a signed record behind each charge.
BuildingOne REST contract — x402 settlement live on Base mainnet, USDC and EURC. Your agent makes the call, Arispay clears the payment. Idempotent on every write, signed on every event.
ShoppingYour payment rails can see that the agent is trusted and funded. You can safely accept agentic payments.
One REST surface. Every payment idempotent, every webhook signed, every dollar capped by limits you control. Delegated custody via Coinbase CDP, live on Base mainnet.
The boring details — rails, fees, SDKs — that actually decide whether a payments product is good.
We don't believe in long feature lists. These are the four design decisions that do the work — each one you can verify against the API, the SDKs, and the chain.
Live mainnet settlement for machine-to-machine micropayments. Every transaction replay-protected by nonce.
x402 is live today. Card and bank rails are in development behind the same API contract — one API surface, one webhook contract — and go live when the first processor agreement signs.
Coinbase CDP holds the signing key. Your agent holds the policy. No self-custody required.
HMAC-SHA-256 on every event. Automatic retry with jittered backoff. Idempotent payment endpoints.
No black-box compliance claims — the controls are architectural. Custody is delegated, card data never enters our systems, and spend limits are enforced server-side on every payment. Three auth paths, one write surface, append-only audit trail.
The short version of what Arispay is, what it costs, and what is live today.
Arispay is payment infrastructure for agentic commerce — software that lets AI agents pay merchants online under developer-controlled guardrails: spend limits, delegated custody via Coinbase CDP, and signed receipts. x402 settlement is live on Base mainnet (USDC and EURC); card and bank rails are in development.
x402 is an open protocol for machine-to-machine payments over HTTP. Arispay runs an open x402 facilitator that verifies and settles payments on Base mainnet in USDC or EURC — at zero fee.
The developer installs the payagent SDK, sets spend limits, and funds the agent through delegated custody at Coinbase CDP. When the agent calls a merchant endpoint, paygate middleware returns a price, the agent signs the payment, and Arispay checks it against the limits server-side before settling.
The open x402 facilitator is free — verify and settle at $0. The delegated platform charges 1% on x402 payments with a 1¢ minimum, and the balance rail defaults to 1.5%. Card rails are still in development, so there is no card pricing yet.
