## 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 trading-time-api-dst-gap-detector-dba594d0
```

Example prompt: Is there a DST gap between the US and Europe right now, and what's the current clock difference in hours? Check using the US-EU pair.

## When to prefer this

Use this endpoint when you need to programmatically detect DST transition gaps between specific international market timezone pairs (US-EU, US-UK, US-CH, EU-AU) and retrieve the exact clock offset in hours at a given moment. Prefer this over general timezone libraries when you need a lightweight, real-time API check specifically tuned for trading-relevant timezone pairs.

## Known failure modes

- Invalid or malformed ISO 8601 timestamp returns an error response
- Unsupported timezone pair value results in a validation error
- Missing required parameters may return a default-based response or error
- Service unavailability on Render infrastructure causes 503 timeouts

## How this service works

Returns whether a given time falls inside a daylight-saving gap between the US and Europe and the current clock difference in hours.

## Output

Returns a boolean indicating whether the given time falls inside a DST gap between the two specified timezone regions, along with the current clock difference in hours between them.
