How to Call (x402 flow)

Pay-to address (Base mainnet USDC):
0x6fc33ac754b82e290945cb8000e8d2f8525b1756

1. Request without payment → get 402 + payment requirements:

curl -X POST ORIGIN/api/v1/call \
  -H "Content-Type: application/json" \
  -d '{"service":"translation","params":{"text":"hello world","target_lang":"zh"},"api_key":""}'

2. Transfer the quoted USDC on Base mainnet to the address above, then retry with your tx hash:

curl -X POST ORIGIN/api/v1/call \
  -H "X-Payment: <your_tx_hash>" \
  -H "X-Payer: <your_wallet>" \
  -d '{"service":"translation","params":{"text":"hello world","target_lang":"zh"},"api_key":""}'

3. Server verifies the tx on-chain → returns 200 + AI result. Each tx usable once (replay-protected).

If the API key list is left open, omit x-api-key; otherwise register a key below.

API key (optional)

curl -X POST ORIGIN/guard/register-key \
  -H "Content-Type: application/json" \
