# x402 Video — pay-per-call AI video generation

> No accounts, no API keys, no credit cards.
> HTTP 402 -> pay USDC on Base (eip155:8453) -> video generates.
> Any x402 client works; `@x402/fetch` handles 402 -> pay -> retry automatically.

## Endpoints (live quotes at GET https://api.x402video.com/)

| Endpoint | Output | Price |
|---|---|---|
| POST https://api.x402video.com/generate/seedance-mini/5s-720p | 5s 720p MP4 (cheapest) | ~$0.67 / call |
| POST https://api.x402video.com/generate/seedance-fast/5s-720p | 5s 720p MP4 | ~$1.05 / call |
| POST https://api.x402video.com/generate/seedance/5s-720p | 5s 720p MP4 (highest quality) | ~$1.33 / call |
| POST https://api.x402video.com/generate/seedance-mini/custom | 4-15s, 480p/720p, optional audio | $0.26-$2.00 |
| POST https://api.x402video.com/generate/seedance-fast/custom | 4-15s, 480p/720p, optional audio | $0.40-$3.15 |
| POST https://api.x402video.com/generate/seedance/custom | 4-15s, up to 1080p, optional audio | $0.49-$9.82 |

The 402 response always quotes the exact USDC amount for your request before you pay.
Custom body fields: { prompt, duration 4-15, resolution "480p"|"720p"|"1080p", ratio, seed, generate_audio, camera_fixed }.

## Quickstart (raw curl — see the 402 flow)

curl -i -X POST https://api.x402video.com/generate/seedance-fast/5s-720p \
  -H 'content-type: application/json' \
  -d '{"prompt":"a dog on the moon"}'
# -> HTTP 402 with exact USDC payment requirements (scheme "exact", USDC on Base)
# -> resend with X-PAYMENT header (any x402 client signs this for you) -> 200 { job_id, status_url }
# -> GET https://api.x402video.com/jobs/:id (free) until status "succeeded"
# -> download video_url within 24h (link expires)

Payments are gasless for the buyer (EIP-3009 signature; the facilitator submits the tx).
Prompts are screened before payment — rejected requests (403), rate limits (429),
and capacity rejections (503) are never charged.
