## 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 natural-date-parse-0c224320 -d '<json body>'
```

Example prompt: Parse all the date and time expressions in this text and resolve them to ISO 8601 values in the America/New_York timezone, treating today October 29 2026 as the reference point: 'ship next Friday 3pm, review by end of Q3, and schedule kickoff for next Monday morning'.

## When to prefer this

Choose this endpoint when you need to extract and normalize multiple date and time expressions from unstructured or semi-structured text, especially when relative phrases like 'next Friday', 'end of Q3', or 'in two weeks' need to be anchored to a specific reference instant and timezone. It is particularly valuable for scheduling automation, calendar ingestion, deadline extraction from emails or notes, and any workflow that must convert human-written time references into machine-readable ISO 8601 values. Prefer it over regex-based approaches when ambiguity detection and confidence scoring are important.

## Known failure modes

- Text contains no recognizable date or time expressions — returns empty results
- Reference instant is malformed or out of ISO 8601 format — returns a validation error
- IANA timezone string is invalid — returns a timezone resolution error
- Text exceeds 2000 character limit — request rejected
- Highly ambiguous phrases like 'the 5th' with no month context may resolve with low confidence or be flagged as ambiguous

## How this service works

Finds every date, time, range and period in text and resolves each to an ISO 8601 value with UTC offset plus a start/end span in an IANA timezone, relative to a reference instant. Reports matched text, index, ambiguity flags and confidence.

## Output

Returns a list of parsed date/time mentions, each with the matched text snippet, its character index in the original input, the resolved ISO 8601 datetime with UTC offset, the start and end of the span in the specified IANA timezone, an ambiguity flag, and a confidence score.
