Face Search (10 credits)

Two-step async flow: upload → poll.

Step 1 — Upload

curl -X POST https://gateway.nuwa.world/api/v1/face-search \
  -H "X-API-Key: $NUWA_API_KEY" \
  -F "image=@photo.jpg"

Response (HTTP 202):

{
  "search_id": "abc123",
  "status": "processing",
  "message": "Face uploaded. Poll GET /api/v1/face-search/{search_id} for results."
}

Step 2 — Poll (every 3–5 seconds, no credit cost)

curl https://gateway.nuwa.world/api/v1/face-search/abc123 \
  -H "X-API-Key: $NUWA_API_KEY"

While processing:

{ "search_id": "abc123", "status": "processing", "results": [], "total_results": 0 }

When done:

{
  "search_id": "abc123",
  "status": "completed",
  "results": [
    { "index": 0, "score": 95.2, "url": "https://example.com/profile" },
    { "index": 1, "score": 82.1, "url": "https://social.example/user" }
  ],
  "total_results": 2,
  "max_score": 95.2
}

Processing takes 15–30 seconds. Results expire after 2 hours.
