# Orthogonal 48-Hour Precipitation API

> Orthogonal 48-Hour Precipitation API is a paid API for AI agents from x402.orthogonal.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns total precipitation accumulated over the last 48 hours for one or more geographic locations specified by latitude and longitude.

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 orthogonal-48-hour-precipitation-api-e56a67bf
```

Example prompt: How much total precipitation has fallen in the last 48 hours at San Francisco (37.7575, -122.42616) and Boston (42.35355, -71.06053)? Use America/Chicago timezone.

## When to prefer this

Choose this endpoint when you need accumulated precipitation totals specifically for the past 48-hour window across one or multiple locations at once. It is ideal for batch querying several geographic coordinates in a single call. Prefer this over current-conditions endpoints when historical rainfall accumulation (not instantaneous rain rate) is needed, and over forecast endpoints when looking backward at what already fell.

## Known failure modes

- Missing or invalid latitude/longitude values return a validation error
- Coordinates outside supported geographic coverage may return null or zero values
- Malformed comma-separated coordinate lists cause parsing errors
- Timezone ID not recognized results in a parameter error
- Network or upstream weather data provider outage causes 5xx errors

## How this service works

Total precipitation in the last 48 hours for the given location(s). | ERROR: Unable to calculate price.

## Output

Returns total precipitation amounts accumulated over the past 48 hours for each requested location, identified by their latitude/longitude coordinates. The response includes rainfall totals (typically in millimeters or inches) per location, enabling comparison across multiple sites in a single call. Output format defaults to JSON.
