## 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 orthogonal-daily-precipitation-api-599d52f0
```

Example prompt: Can you pull the daily precipitation data for San Francisco (37.7575, -122.42616) and Boston (42.35355, -71.06053) from January 4 to February 4, 2024, in the America/Chicago timezone? I need precipitation amount, type, and probability for each day.

## When to prefer this

Choose this endpoint when you need structured daily precipitation data — including type differentiation (rain/snow/mixed) and probability — for one or multiple geographic coordinates over a custom date range. It is especially useful when you need a seamless blend of historical observations and future forecasts in a single call, or when querying multiple locations simultaneously using coordinate pairs.

## Known failure modes

- Invalid or out-of-range latitude/longitude values return an error
- Mismatched number of latitude and longitude values cause a parameter error
- Dates outside supported historical or forecast range may return empty or partial results
- Invalid timezone ID returns a format or validation error
- Missing required query parameters (start, end, latitude, longitude) result in a 400 bad request
- Price calculation failure may block the request from processing

## How this service works

Returns comprehensive daily precipitation data for the given time range and location(s). Each day includes precipitation amount, type (rain/snow/mixed), probability (for forecasts), and data source. Seamlessly combines historical observations with forecast data depending on the requested time range. | ERROR: Unable to calculate price.

## Output

Returns a list of daily records for each requested location, each including: precipitation amount, precipitation type (rain/snow/mixed), probability (for forecast days), and data source. Seamlessly merges historical observation data with forecast data based on the requested date range.
