## 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 one-engine-iso-date-extractor-589a8bcf -d '<json body>'
```

Example prompt: Can you pull out all the ISO-formatted dates from this text? Here's the content: 'The project kicked off on March 5th, 2024, with a midpoint review scheduled for the fifteenth of June and a final deadline of 2024-12-01.'

## When to prefer this

Choose this endpoint when you need to extract and normalize dates from free-form or semi-structured text into ISO format, especially in automated agent pipelines where consistent date formatting is critical. It is ideal for processing contracts, emails, logs, articles, or any unstructured document where dates appear in mixed or natural language formats. At $0.004 per call with pay-per-use x402 billing on Base, it suits high-volume agent workflows without subscription overhead.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No dates found in text — returns empty result set
- Ambiguous date formats (e.g. '01/02/03') may be parsed incorrectly or omitted
- Payment failure via x402 on Base — call not executed
- Malformed input JSON with missing 'text' field — validation error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output
