# x402

> Set up Browser Use Cloud payments with x402 — pay per request from a crypto wallet (USDC on Base mainnet), no signup or API key.

The `x402` skill walks your agent through setting up [Browser Use Cloud payments with x402](/cloud/guides/x402) — pay per request from a crypto wallet (USDC on Base mainnet), with no signup, API key, or credit card. It guides wallet setup, funding, writing the key to `.env`, and a \~\$1 test run. The SDK is the easiest path, and non-SDK flows are available via x402-aware client libraries. Use it when you want pay-per-use access without an API key.
