## Input

```json
{ "url": "https://example.com" }
```

## Output (after payment settles)

```json
{
  "service": "AgentTrust Verify",
  "target": "example.com",
  "risk_level": "LOW | MEDIUM | HIGH",
  "trust_score": 0,
  "confidence": 0.0,
  "interaction_recommendation": "PROCEED_WITH_NORMAL_CAUTION | REVIEW | AVOID",
  "limitations": ["Observable technical signals only — not proof of identity, legitimacy or safety."],
  "checks": [{ "id": "https", "status": "pass | fail | warn | unknown", "detail": "..." }],
  "deductions": [{ "reason": "...", "points": 0 }],
  "evidence": ["..."],
  "checked_at": "ISO-8601",
  "payment": { "settled": true, "transaction": "..." }
}
```

Checks that the runtime could not complete are returned with status "unknown" and
reduce "confidence". They are never reported as passing.

## Flow

1. POST /api/verify without payment -> HTTP 402 with a PAYMENT-REQUIRED header.
2. Build an exact-scheme Algorand USDC payment for the advertised requirements.
3. Retry with the PAYMENT-SIGNATURE header.
4. The GoPlausible facilitator verifies and settles on Algorand.
5. The response body contains the verification result; PAYMENT-RESPONSE carries settlement proof.
