Extracts JPEG still frames from a completed production video render at $0.002 per frame, accepting specific timestamps or per-second sampling

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability contentrewardsai-frame-extractor-def4d638 -d '<json body>'
```

Example prompt: Extract JPEG stills from my completed production render abc123xyz — pull a frame every second for the first 30 seconds.

## When to prefer this

Use this endpoint when you have a completed production render (not a staging/watermarked render) and need to extract JPEG stills at specific timestamps or at regular per-second intervals. For staging/free frame extraction from watermarked renders, use the separate stage stills endpoint instead. Prefer this when you need up to 60 frames per call and are billing precisely at $0.002/frame.

## Known failure modes

- render_id not found or not in PRODUCTION status — render must be fully completed before frame extraction
- more than 60 frames requested in a single call — reduce number of timestamps or shorten duration
- timestamp out of range — times must be between 0 and 3600 seconds and within actual render duration
- payment failure — insufficient USDC balance for x402 micropayment
- duration_seconds exceeds 3600 — maximum supported duration is 1 hour

## How this service works

Extract jpg stills from a completed PRODUCTION render at $0.002 per frame (1s @ $0.10/min, 3 dp). Body: { render_id, times?, every_second?, duration_seconds? }. Max 60/request. Stage stills: POST /api/agent/shotstack/render/{id}/frames (SIWX, free).

## Output

Returns JPEG still images extracted from the specified production render at the requested timestamps or at per-second intervals, up to 60 frames per request, billed at $0.002 per frame.
