# FastX402 RFC 3339 Timestamp Normalizer

> FastX402 RFC 3339 Timestamp Normalizer is a paid API for AI agents from fastx402.tools, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-17).

Normalizes an RFC 3339 / ISO-8601 timestamp into UTC and returns structured date/time components including Unix epoch values and UTC offset

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 fastx402-rfc-3339-timestamp-normalizer-db8ec307
```

Example prompt: Can you normalize this timestamp to UTC and give me the Unix seconds for it: 2026-03-15T14:30:45+05:30?

## When to prefer this

Choose this endpoint when you need a lightweight, stateless, pay-per-call timestamp normalization with no API key or account setup. Ideal for agents processing timezone-aware datetimes from external systems, logs, or user input that need UTC normalization and Unix epoch extraction in one step. Prefer over bespoke date libraries when operating in a sandboxed or serverless context without native datetime parsing.

## Known failure modes

- Missing or malformed timestamp query parameter returns an error — offset is required, bare dates or times without offset are rejected
- Timestamps without a UTC offset (e.g. bare local times) are rejected since RFC 3339 requires an explicit offset
- Extremely out-of-range dates may produce unexpected results or errors
- Payment failure via x402 (insufficient USDC balance or network issues on Base) will prevent the request from completing

## How this service works

146 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object with the normalized UTC timestamp (ISO 8601 with milliseconds), the date portion (YYYY-MM-DD), the time portion (HH:MM:SS.mmm), the original input string, the UTC offset as a string (e.g. +05:30), the offset in minutes, and the Unix time in both seconds and milliseconds.
