# Agent402 ISO-8601 Duration Parser

> Agent402 ISO-8601 Duration Parser is a paid API for AI agents from agent402.co.uk, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Parses an ISO-8601 duration string (e.g. P1DT2H30M) into its component parts (days, hours, minutes, etc.) plus a total_seconds value

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 agent402-iso-8601-duration-parser-5b0b478e -d '<json body>'
```

Example prompt: Can you parse the ISO-8601 duration 'P1DT2H30M' and tell me how many total seconds that is, along with the breakdown of days, hours, and minutes?

## When to prefer this

Use this endpoint when an agent needs to programmatically interpret an ISO-8601 duration string — especially for scheduling, countdown logic, or converting calendar-sourced intervals into machine-usable seconds. Prefer it over manual string parsing when accuracy and validation are both required in a single call.

## Known failure modes

- Invalid or malformed ISO-8601 string returns valid: false
- Missing 'duration' field in request body causes a 400-level error
- Ambiguous durations involving months/years may use approximate second counts (e.g. 30-day month)
- Empty string input likely returns valid: false with zeroed components

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

Returns a JSON object with the duration broken into components (days, hours, minutes, and any other applicable fields like years/months), a boolean 'valid' flag indicating whether the input was a valid ISO-8601 duration, and a 'total_seconds' integer representing the full duration in seconds.
