How to Pay (x402 Flow)
Every paid endpoint follows the same flow:
Step 1: POST without payment → HTTP 402
curl -s -X POST https://agent.kihustle.tech/services/impressum-check/jobs \
-H "Content-Type: application/json" \
-d '{"url": "https://example.de", "country": "DE"}'
Response: HTTP 402 PAYMENT-REQUIRED
{
"statusCode": 402,
"payment": {
"network": "eip155:8453",
"asset": "USDC",

"expiresAt": "2026-01-01T00:05:00.000Z"
}
}
Step 2: Pay the exact amount to payTo on Base USDC
