# MyRadar Historical Weather Time Series at Multiple Points

> MyRadar Historical Weather Time Series at Multiple Points is a paid API for AI agents from agents.myradar.dev, paid per call via MPP, price unknown, status unknown (last checked 2026-10-12).

Returns a continuous historical weather time series for one or more lat/lon locations over a specified time window.

## 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 agents-myradar-dev-myradar-historical-weather-time-series-at-multiple-d97820ab
```

Example prompt: Pull the historical weather time series from MyRadar for locations [[41.5,-105.1],[36.1,-96.1]] between January 10, 2024 at midnight and January 15, 2024 at noon — I need road temperature, precipitation, and wind for each point across that whole window.

## When to prefer this

Use this endpoint when you need historical (past) weather or road weather conditions across a continuous time window for one or more specific geographic coordinates. It is the right choice when you need multi-point batch retrieval of past conditions rather than a current forecast. Prefer this over the forecast endpoint when the time window is entirely in the past, and over hail/wind history endpoints when you need continuous time-series data rather than discrete severe event records.

## Known failure modes

- Invalid time format (not YYYYmmdd.HHMM) returns a 400 or validation error
- Malformed latlons JSON array causes a parsing error
- begin_time after end_time returns an error or empty result
- Coordinates outside supported coverage area may return empty or null data
- Requesting a very long time window or many points may increase latency or hit payload limits
- Authentication or credit failures return 401/402 errors

## How this service works

Returns a continuous time series between begin_time and end_time (both YYYYmmdd.HHMM) for each point in latlons, a JSON array of [lat, lon] pairs.

## Output

A continuous weather time series for each requested lat/lon point covering the full window from begin_time to end_time. Each data point in the series likely includes meteorological variables such as road and surface temperature, road condition, precipitation, cloud cover, wind speed, and delay risk, consistent with MyRadar's road weather product. Data is returned per-point in time-ordered intervals.
