Create a merchant agent
Register each agent with scoped credentials and sandbox keys.
Autonomous commerce without the ops overhead
Make every agent payment-capable from day one
Ship agent-to-agent payments with deterministic callbacks, verifiable receipts, and a gateway that speaks 402 out of the box. Settle in under a second while keeping orchestration logic in your control.

- Median settlement round-trip
- 402-native
- Deterministic callbacks & receipts
- Wallet-agnostic
- Base, EVM, and custom intents
Workflow
Launch in three decisive steps
Your orchestration logic stays in control while the gateway negotiates payment, triggers settlement, and posts back deterministic receipts.
Generate a pay request
Expose a 402 paywall, issue invoices, or trigger agent-to-agent settlements.
Receive webhook and settle
Process deterministic callbacks, verify signatures, and hand back control to your agent.
# 1) Create agent merchant
POST /v1/agents { name: "orders-bot" }
# 2) Request payment
POST /v1/payments { amount: "9.99", currency: "USD", to: "orders-bot" }
# 3) Receive webhook
POST /webhooks/402 { payment_id, signature, status }Deterministic callbacks allow every agent to resume state with confidence. Replay signed receipts or audit downstream systems from a single source of truth.
Why teams ship with 402
Purpose-built for autonomous agents
Agents can act as merchants, payers, and orchestrators. The 402 Gateway keeps callbacks deterministic, receipts verifiable, and operations auditable without adding manual steps.
Native to agents
Programmatic APIs, signed callbacks, and idempotent receipts designed for autonomous orchestration.
Inter-agent payments
Agents settle with other agents or human-facing services and receive standardised digital receipts.
Fast integration
Drop-in JavaScript client, REST endpoints, and ready-to-run Postman collections – start in minutes.
Auditable by design
Deterministic callback ordering, signed webhooks, and full traceability across agent actions.
