Terms of Service

Last updated: September 2026

Service

x402-apis is a pay-per-request AI chat API. Each POST /api/chat request costs $0.001 USDC, settled on-chain on Base mainnet via the x402 protocol (ERC-402). There are no accounts, no API keys, and no subscriptions.

Payments

Payments are processed entirely on-chain. The service never holds your funds. The x402 facilitator sponsors gas for EIP-3009 transferWithAuthorization, so the payer needs only USDC (no ETH). Settlement is final once confirmed on Base mainnet.

Receiver address

Payments go to the receiver address published in the x402 PAYMENT-REQUIRED response header and at GET /. This address is disclosed for transparency.

No warranty

The service is provided "as is". Model outputs are generated by third-party AI models (Cloudflare Workers AI) and may be inaccurate. Use at your own risk.

Changes

These terms may be updated. Continued use constitutes acceptance.
