## 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 secondeyesai-com-231c6249
```

Example prompt: Can you transcribe this podcast episode at https://example.com/episode42.mp3 and give me a summary, the top key points, and answer the question 'What are the main takeaways about AI regulation?'

## When to prefer this

Choose this endpoint when you need both a raw transcript AND its semantic meaning (summary, key points, Q&A) from a single call, with built-in deterministic validation guaranteeing the output is schema-conformant and meaning is grounded in the source — not hallucinated. Prefer over generic transcription APIs when evidence-only attestation and self-validated quality matter, or when the source is a podcast, voice note, PDF, or video URL rather than an uploaded file.

## Known failure modes

- URL is not publicly accessible — returns error indicating inaccessible resource
- Audio/video format not supported or cannot be decoded — returns decode error
- PDF is encrypted or scanned image-only with no extractable text — returns extraction failure
- Content too short or silent — words-per-minute validation fails
- Network timeout fetching remote URL — returns fetch error
- Q&A answer not grounded in transcript — validation blocks response and returns grounding error

## How this service works

transcribe-extract: turn any public audio, voice note, podcast, PDF, or video URL into a transcript plus its meaning — summary, ranked key points, and grounded Q&A. Deterministically validated (schema, words/min, no decode loop, meaning grounded in transcript) before it is served; evidence-only attestation, never a claim of accuracy.

## Output

Returns a validated transcript of the media or document, a prose summary, a ranked list of key points, and grounded Q&A answers derived solely from the transcript content — all deterministically validated for schema conformance, words-per-minute plausibility, and meaning grounded in the transcript before being served.
