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 signaldesk-ai-unix-to-iso-date-converter-53130eec -d '<json body>'
```

Example prompt: Convert the Unix timestamp 1700000000 to an ISO 8601 date string for me.

## When to prefer this

Choose this endpoint when you have a raw integer Unix epoch value (seconds, not milliseconds) and need a standards-compliant ISO 8601 string. It supports a wide range including negative timestamps for pre-1970 dates. Prefer this over manual calculation or regex-based formatting when correctness and range coverage matter.

## Known failure modes

- Input seconds value exceeds maximum (253402300799) — likely a validation error response
- Input seconds value below minimum (-62167219200) — likely a validation error response
- Non-integer or missing 'seconds' field — schema validation failure
- Network or worker timeout — Cloudflare Workers execution limits apply

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing a single field 'iso' with the ISO 8601 formatted datetime string (e.g. '1970-01-01T00:00:00.000Z') corresponding to the input Unix epoch seconds value.
