Solizardking x402 paid API requests
Goal
Make HTTP requests to x402-protected endpoints. The CLI automatically detects 402 Payment Required responses, builds and signs a payment transaction with your local wallet, and retries the request with the payment proof.
Command
mp x402 request \
--method POST \
--url <x402-endpoint-url> \
--body '<json-body>' \
--wallet <wallet-name-or-address> \
--chain solana
Available x402 endpoints
| Endpoint | Cost | Input |
|---|---|---|
https://agents.moonpay.com/x402/upgrade |
$1-$20 | {"duration": "day"} or {"duration": "month"} |
Example flow
- User: "Upgrade my rate limit for a day."
- Run:
mp upgrade --duration day --wallet my-wallet --chain solana - The CLI handles the 402 payment flow automatically and applies the upgrade.
Notes
- Requires a local wallet with USDC on Solana or Base.
- Payments accepted on Solana mainnet and Base.
- If the request fails (status >= 400), the payment is not settled — you don't pay for errors.
- Use moonpay-auth to set up a local wallet first.
