Request
An autonomous agent calls an AgentPay-enabled API like any other HTTP resource.
GET /api/premium Payment infrastructure for autonomous software
APIs can now
charge themselves.
AgentPay turns HTTP 402 into an autonomous USDC payment flow for AI agents. Discover a price, pay within policy, and continue — no accounts, invoices, or human checkout.

The thesis
Software is becoming an economic actor.
Agents can browse, reason, and act — but they still hit a human checkout when value must move.
AgentPay gives APIs a machine-native price and agents a policy-controlled way to pay it. One familiar HTTP status becomes a market primitive: ask, quote, settle, continue.
Built for the point where API infrastructure becomes agent commerce.
The protocol
One request.
One payment.
No friction.
HTTP 402 → USDC → HTTP 200
Discover & pay
HTTP 402 returns exact USDC terms. Local policy approves the origin, chain and spend.
402 · 0.01 USDCVerify & unlock
The API verifies the onchain receipt, atomically claims it, and releases the resource.
200 · premium data Live mainnet proof
Not a mockup.
A paid API.
Call the public endpoint. It quotes exactly $0.01 in real USDC on Base. A verified transaction hash unlocks the premium response once — and only once. The returned text is intentionally fixed and non-sensitive: this proves settlement, not authenticated access control.

The primitive is
already working.
01
HTTP-native
Pricing travels with the request instead of through accounts, invoices or a separate checkout stack.
02
Policy-controlled
Agents enforce origin, chain, recipient, token and maximum spend before signing anything.
03
Verified onchain
Receipts, confirmations, official USDC transfer logs and durable replay protection gate every response.
