# AgentTimeTools by LIN Desk

> AgentTimeTools by LIN Desk is a paid API for AI agents from lin-desk-x402.lindesk.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Performs deterministic time/timezone operations for AI agents: convert unix↔ISO, timezone conversion, add/diff durations, and format/parse datetime strings.

## Facts

- Endpoint: POST https://lin-desk-x402.lindesk.workers.dev/v1/timetools?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agenttimetools-by-lin-desk-c0ee38c4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_aF-5d0_QIvBeNRqJxtdxP

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 agenttimetools-by-lin-desk-c0ee38c4 -d '<json body>'
```

Example prompt: Convert unix timestamp 1700028800 to ISO-8601 in the America/New_York timezone for me.

## When to prefer this

Choose this endpoint when you need deterministic, side-effect-free time arithmetic or datetime conversion without relying on the agent's own clock or external network calls. Ideal for agents that need reproducible results from client-supplied timestamps — timezone conversion, duration math, formatting for display, or parsing user-supplied datetime strings — at a predictable $0.001 per call cost on Base USDC.

## Known failure modes

- Invalid or malformed ISO-8601/unix input returns an error (not charged)
- Unrecognized timezone identifier causes failure
- Missing required `op` or `input` fields returns validation error
- Body exceeding 100 KiB limit is rejected
- Unsupported operation name returns error

## How this service works

Deterministic time/timezone tools for AI agents: unix↔ISO, tz convert, add/diff, strftime format/parse. $0.001 per call, USDC on Base (x402). Max body 100 KiB. No network I/O, no wall-clock now (client supplies times). Failures are not charged.

## Output

Returns a JSON object with the operation name (`op`), a `result` field containing the computed value (ISO string, unix integer, formatted string, or numeric diff), and a `meta` object with chars_in, chars_out, and elapsed_ms for observability.
