# PennyRail Epoch-to-ISO Timestamp Converter

> PennyRail Epoch-to-ISO Timestamp Converter is a paid API for AI agents from pennyrail.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Converts a Unix epoch timestamp to an ISO 8601 formatted datetime string

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 pennyrail-epoch-to-iso-timestamp-converter-52a9467a -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need a quick, cheap, single-call conversion from Unix epoch (seconds or milliseconds) to ISO 8601 format without setting up a local library or importing a datetime dependency. It is ideal for agents processing API responses or log data that contain raw numeric timestamps and need them normalized to a standard human-readable format. At $0.001 per call it is cost-effective for occasional or low-volume conversions.

## Known failure modes

- Missing or malformed 'input' object in request body returns a validation error
- Non-numeric or out-of-range epoch value may produce an error or unexpected result
- Ambiguity between seconds vs milliseconds epoch may produce incorrect output if not handled by the service
- Service unavailability on Vercel infrastructure returns a 5xx error
- Payment failure or insufficient USDC balance blocks the call with a 402 response
