x402 is an open protocol from Coinbase that lets AI agents pay for API calls automatically with USDC on Base chain. Your agent sends a request, gets a 402 response with payment details, signs a USDC authorization, and the payment is settled on-chain. No API keys, no accounts, no signup. Install @x402/fetch from npm to get started.
Create an API key, send USDC to our wallet on Base chain, then call POST /api/credits/topup with your key and transaction hash. Credits are added instantly after on-chain verification. 1 USDC = 500 credits. Even $0.01 works.
Yes. One API key gives you access to all services through the unified gateway at /v1/{service}/{endpoint}. Same key for geolocation, crypto prices, web scraping, screenshots, code execution — everything.
USDC on Base (Layer 2 — low gas fees, ~2 second confirmations) and Monero (XMR) for privacy-focused users. x402 auto-pay uses Base Sepolia testnet during beta. XMR credits are calculated at the live XMR/USD rate.
Free tier: 60 requests/minute, 50 requests/day. API key users: 300 requests/minute. x402 users: 300 requests/minute. Need more? Contact us.
The API gateway handles thousands of requests daily with 44 services running 24/7. All services are health-monitored every 5 minutes. x402 payments use Coinbase's facilitator for on-chain settlement.
