Live on Base Mainnet

Your API,
paid by AI agents
automatically.

AI agents cannot use credit cards. They use wallets. ReqCast lets your tool collect autonomous USDC payments from AI agents without writing a single line of payment code.

How it works

Three players.
One infrastructure.

ReqCast sits between AI agents and the tools they need to call. It handles all payment verification, splits and receipts so neither side has to build any of it.

Player 01
⚡
Tool Developer
You built an API, an LLM wrapper or a specialized data service. You want to charge per call and get paid without spending weeks building payment infrastructure.
"I want to monetize my tool. I do not want to learn blockchain payment rails to do it."
Player 02
🤖
AI Agent
An autonomous agent that needs to call paid tools to complete tasks. It holds USDC in a wallet. It cannot fill out checkout forms, complete OAuth flows or use a credit card.
"I need to pay for API calls with no human involvement whatsoever."
Player 03
RC
ReqCast
The payment layer between the two. ReqCast intercepts the agent request, verifies USDC on-chain, fires your callback, splits the payment and writes a tamper-evident receipt. Every time. Automatically.
You receive 95% the moment the agent calls. No invoices. No chargebacks. No payment code to write or maintain.
Transaction flow

Every transaction.
Fully automatic.

Step 01
🤖
Agent sends request
HTTP POST hits /pay/{tool-name} on ReqCast with the agent payload.
Step 02
402
402 returned
ReqCast returns the tool price. The x402 client signs a USDC payment automatically.
Step 03
✓
Verified on-chain
USDC transaction verified via Coinbase facilitator. No valid payment means no execution.
Step 04
→
Your tool runs
ReqCast POSTs to your callback URL with the payload and X-ReqCast-Verified: true.
Step 05
💸
You get paid
95% USDC lands in your wallet on-chain. Receipt written. Agent receives the result.
Economics

95% is yours.
Every single time.

No monthly fees. No minimum volumes. No invoices to chase. ReqCast takes 5% per transaction to keep the infrastructure running. Everything else goes straight to your wallet the moment the transaction settles.

High-value tools like LLM wrappers, specialized datasets and premium APIs generate real revenue at lower call volumes. Price your tool to reflect what it delivers.

Integration

One registration.
One callback endpoint.
You are live.

Register your tool once. Build a standard HTTP endpoint that returns your result. ReqCast handles the rest.

1
Register your tool
One POST to /register with your price, wallet and callback URL.
2
Build your callback
A standard HTTP endpoint. ReqCast calls it after payment clears.
3
Verify receipts
Every payment has a tamper-evident receipt with on-chain proof.
