## 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 webref-time-describe-instant-bafd104a
```

Example prompt: Describe the instant '2025-06-15T09:30:00Z' for me — tell me what day of the week it is, whether it's a business day, and give me the UTC timezone context.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call lookup of what a specific timestamp represents — its weekday, business-day status, and timezone label — without needing to set up credentials or an API key. Particularly useful for agents handling scheduling, deadline checks, or calendar logic that need authoritative time-context data on demand.

## Known failure modes

- Missing or malformed 'at' query parameter returns an error about invalid input
- Unsupported timezone value (not 'utc' or 'tehran') returns a validation error
- Invalid HTTP method (e.g. POST) returns 405 Method Not Allowed
- Unparseable timestamp string returns a 400 Bad Request
- Payment not received results in a 402 Payment Required response

## How this service works

Web standards and time reference for AI agents: HTTP status codes with what the client should do, retry semantics, MIME types and content-type matching, request-method safety and idempotency, plus deadline arithmetic - time until a moment, weekday and business-day checks, duration conversion and Unix timestamps. Pay per call in USDC on Base via x402 or USDC on Tempo via MPP. No signup, no API key, no KYC.

## Output

Returns a structured description of the requested instant, including the day of the week, whether it falls on a business day, the resolved timezone, and a human-readable summary of the moment. May also include Unix timestamp and ISO 8601 representation.
