AgentsPay

Powered by Solana

Payments infrastructure built for AI agents.

Agents pay for APIs, data and compute per request over x402, in USDC on Solana. No cards, no sign-ups.

Works wherever your agent runs

Why now

The web was built for humans. Agents need a different way to pay.

01

Cards and checkout forms assume a person with a billing address. Agents have neither.

02

Every new service means a new account, key and invoice. An agent can’t sign up on its own.

03

HTTP 402 has been reserved for payments since the early web. Open standards such as x402 are now putting it to use.

Agent to agent

One agent pays another over x402, in USDC on Solana, per request, with no human in the loop.

Amounts are illustrative.

How it works

01

Add one x402 middleware to your service and set a price per request.

02

On an x402 payment request, the agent pays from its own wallet, within the limits you set.

03

USDC arrives at your Solana address as soon as the response is served.

Safety

Every agent wallet runs inside limits you define: a daily budget, an allowlist of services and a cap on each x402 payment.

FAQ

What is AgentsPay?
AgentsPay lets AI agents pay for APIs, data and compute per request, in USDC on Solana, using the x402 standard. No cards, no sign-ups, no API keys.
How does x402 work?
When a service wants to be paid, it answers a request with HTTP 402 and a price. The agent pays and repeats the request with proof of payment, and the service returns the result.
Why Solana?
Solana has low fees and fast confirmation, which matters when a single payment can be a fraction of a cent. A large share of x402 activity already happens there.
Which currency do you use?
USDC, a dollar stablecoin, so prices and payouts stay stable and there is no volatility to manage.
Do I need an account, a card or an API key?
No. A wallet is enough.
How do you keep an agent from overspending?
Every agent wallet runs inside limits you define: a daily budget, an allowlist of services and a cap on each x402 payment.
How does AgentsPay make money?
We take a small fee on every x402 payment settled on Solana through AgentsPay.
