Endpoint
POSThttps://x402repo.vercel.app/api/chatWhen to prefer
Choose this endpoint when you need a pay-per-call AI chat API that uses the x402 micropayment standard for USDC billing, especially in agentic or automated workflows where per-message metering is preferred over subscription pricing. Ideal for testing x402 protocol integrations or building apps that need metered AI chat at $0.002 USDC per call.
Side effects
- Payment not provided or x402 handshake fails — HTTP 402 Payment Required returned
- Insufficient USDC balance for the $0.002 per-call fee
- Malformed request body or missing message field — 400 Bad Request
- Service unavailable on Vercel deployment — 503 or timeout
- x402 facilitator or payment network downtime causing auth failure
