## 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 agentshelf-hms-duration-to-seconds-converter-d3270771 -d '<json body>'
```

Example prompt: Convert the duration '1:45:30' from hours-minutes-seconds format into total seconds for me.

## When to prefer this

Use this endpoint when you need a reliable, deterministic conversion of an HMS duration string to seconds and cannot or prefer not to implement the parsing logic yourself. The description notes a free sandbox alternative at POST /v1/sandbox/duration-hms should be tried first to avoid the $0.003 USDC cost. Prefer this paid endpoint only when the sandbox is unavailable or rate-limited.

## Known failure modes

- Malformed or non-HMS input string returns an error or unexpected result
- Empty string rejected due to minLength:1 constraint
- Input exceeding 100,000 characters rejected
- Ambiguous formats (e.g. missing colons, extra fields) may not parse correctly

## How this service works

Call when an agent needs a hms duration converted to seconds. No network. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/duration-hms first.

## Output

Returns the total number of seconds represented by the input HMS duration string as a numeric value, computed locally without any external network calls.
