## 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 manylives-subtitle-check-8ac4c0a4 -d '<json body>'
```

Example prompt: Check this SRT file for subtitle quality issues — make sure reading speed stays under 20 characters per second and flag any times the name 'Anna' is misspelled as 'Ana': [paste SRT text here].

## When to prefer this

Use this endpoint when you need automated, per-cue quality assurance of subtitle files against configurable broadcast or streaming standards (reading speed, line length, CPS, timing gaps) and optional glossary enforcement. Prefer this over manual review or generic text analysis when you need structured issue reports with exact timestamps and cue numbers, suitable for pipeline integration before subtitle delivery.

## Known failure modes

- Malformed or unparseable SRT/VTT input returns an error
- Missing 'subtitles' field returns a validation error
- Limits object with invalid keys or types may be ignored or cause an error
- Very large subtitle files may time out or be truncated
- Glossary with incorrect JSON structure may not be applied
