## 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 saylor-innovations-data-desk-singapore-2-hour-weather-nowcast-f5320fe9
```

Example prompt: What's the current 2-hour weather nowcast for Tampines in Singapore — is it raining there or expected to rain soon?

## When to prefer this

Use this endpoint when you need near-real-time Singapore weather conditions or rain status at the sub-island (neighbourhood) level, sourced directly from NEA. Prefer this over generic weather APIs when Singapore-specific, area-level granularity across all 47 NEA zones is required, or when you need to identify exactly which neighbourhoods are experiencing rain in the current 2-hour window.

## Known failure modes

- NEA upstream unavailable — empty or null response with degraded data
- Invalid area name query returns empty area_filter result or full island data
- Stale data if NEA hasn't refreshed — check valid_to timestamp
- Network timeout if upstream NEA API is slow
- No areas with rain — rain_areas returns empty array (not an error)

## How this service works

Singapore two-hour weather nowcast for 47 areas from NEA - forecast per area with coordinates, an island summary and the areas expecting rain

## Output

A JSON object containing: an array of per-area forecasts (area name, weather condition, latitude/longitude), an island_summary array aggregating forecast conditions across areas, a rain_areas list, a count of areas_with_rain, validity window timestamps (valid_from, valid_to), the data source attribution, and an optional note or area_filter field if a specific area was queried.
