## Question
Unit price x 30/100/1000 calls: the budget table for leads.

## Answer in 30 seconds
POST `/tools/thumbnail_creation` on `https://x402vid.com`. Price: **$0.50 USDC** per call (x402, Base `eip155:8453`). Best for: premium render; filter rejections are never charged.

## Copy-paste request
```bash
curl -s -X POST https://x402vid.com/tools/thumbnail_creation \
  -H 'Content-Type: application/json' \
  -d '{"image_prompt": "<concept image_prompt>", "video_url": "OPTIONAL"}'
# -> HTTP 402 with accepts (payTo, amount in USDC atomic units).
# Sign with your wallet, retry with: -H 'X-PAYMENT: <base64 payload>'
```

## Response shape (deterministic JSON)
Returns signed image URL composited via Muse Image. Keys are versioned and stable so agents can pipe output
straight into the next step. Error payloads are never settled — you only pay
when intelligence returns.

## Cost math
Unit price `$0.50` x volume. 30 calls = $15.00, 100 calls = $50.00, 1000 calls = $500.00. No subscription, no key rotation, no unused-seat waste.
