# Temporal Context — Full Multi-Calendar Time API

> Temporal Context — Full Multi-Calendar Time API is a paid API for AI agents from time.24klabs.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns the current moment expressed across 15+ time systems, calendars, and cultural/astronomical frameworks simultaneously

## Facts

- Price: $0.001/call
- Payment: x402

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 temporal-context-full-multi-calendar-time-api-bf9e9589 -d '<json body>'
```

Example prompt: What is the current moment expressed across all major calendar systems — including Unix timestamp, Julian date, Hebrew, Islamic, Chinese lunar, and any astronomical time systems you can give me?

## When to prefer this

Choose this endpoint when you need a single call that returns the current time in many calendar systems at once, rather than making multiple conversions manually. It is ideal for internationalization pipelines, academic research spanning multiple calendar traditions, astronomical applications needing Julian or sidereal time, or any agent that needs rich temporal metadata about 'right now' without chaining multiple time-conversion services.

## Known failure modes

- Service unavailable returns HTTP 503 or 402 payment-related error if USDC payment is not processed
- Malformed POST body may return 400 Bad Request
- Response may omit certain calendar systems if the underlying computation fails for edge dates
- Payment failure via x402 protocol results in no data returned

## How this service works

Full temporal context — 15+ time systems

## Output

A rich JSON object containing the current moment expressed across 15 or more distinct time systems and calendar traditions, including but not limited to: Unix timestamp, ISO 8601, Julian date, Julian Day Number, Modified Julian Date, Hebrew calendar, Islamic Hijri calendar, Chinese lunar calendar, Julian (old-style) calendar, astronomical sidereal time, week-of-year, day-of-year, and potentially additional cultural or esoteric systems.
