## How to Pay (x402 Flow)

Every paid endpoint follows the same flow:

### Step 1: POST without payment → HTTP 402

```bash
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`

```json
{
  "statusCode": 402,
  "payment": {
    "network": "eip155:8453",
    "asset": "USDC",
    "amount": "0.05",
    "payTo": "0x1c8b3C34Dca2Ba2A71598f1F9E0BC2a04A0Bea36",
    "quoteId": "qt_abc123",
    "expiresAt": "2026-01-01T00:05:00.000Z"
  }
}
```

### Step 2: Pay the exact amount to `payTo` on Base USDC

Use your agent wallet (CDP, Permit2, or any x402-capable wallet). Save the transaction hash.

### Step 3: Retry with PAYMENT-SIGNATURE

```bash
curl -s -X POST https://agent.kihustle.tech/services/impressum-check/jobs \
  -H "Content-Type: application/json" \
  -H "PAYMENT-SIGNATURE: 0x<tx_hash>" \
  -d '{"url": "https://example.de", "country": "DE"}'
```

### Step 4: GET the result

```bash
curl -s https://agent.kihustle.tech/services/impressum-check/jobs/<job_id>/result
```
