Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 halowerk-buerowerk-absolute-date-token-extraction-for-meeting-5239bcbb -d '<json body>'
```

Example prompt: Take this meeting transcript — here are the segments with speaker labels and timestamps — and extract all the absolute date tokens from what was said, resolving any relative references like 'next Tuesday' or 'end of the month' against the timeline.

## When to prefer this

Use this endpoint when you have structured meeting transcript data (with timestamps and speaker labels) and need to extract and resolve date references into absolute tokens. It is specifically designed for the meeting context and handles both the flat segments format and the richer transcript_package format with media metadata. Prefer this over general NLP date extractors when your input is already segmented with timing information.

## Known failure modes

- Segments array is empty or missing required fields (start, end, text) — returns 400 validation error
- start or end timestamps exceed allowed maximums (14400s for segments, 1801s for cues) — returns validation error
- text fields exceed 3000 character limit per segment — returns 400 error
- No date references present in transcript — returns empty token list
- Both segments and transcript_package omitted — returns 400 missing input error
- Payment not provided or insufficient — returns 402 Payment Required
