## 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 iso-date-validate-f1c0c134 -d '<json body>'
```

Example prompt: Can you check if '2024-13-45T99:00:00Z' is a valid ISO 8601 date string?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call ISO date validation without spinning up your own date parsing library — especially useful in agent pipelines where you want a trusted external check on date format conformity before persisting or forwarding data. Prefer this when validating individual date strings on-demand rather than batch processing large datasets.

## Known failure modes

- Missing or empty 'value' field returns an error response
- Malformed request body causes a 400-level error
- Service unavailability on Render free tier may cause cold-start timeouts
- Payment failure via x402 protocol blocks the request before validation occurs

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output
