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 forgemesh-historical-weather-by-coordinates-78450da8 -d '<json body>'
```

Example prompt: Pull the daily high/low temperatures and total precipitation for Houston (29.76, -95.36) for every day from January 1, 2020 to December 31, 2020 — I need it for a crop yield backtesting model.

## When to prefer this

Choose this endpoint when you need structured historical daily weather data (temperature highs/lows and precipitation) for any worldwide coordinate going back to 1940, especially for quantitative use cases like backtesting, agricultural analysis, insurance risk modeling, or research workflows that require machine-readable JSON output.

## Known failure modes

- Invalid or out-of-range latitude/longitude returns an error
- Date before 1940 may return no data or an error
- start_date after end_date causes a validation error
- Malformed date strings (non YYYY-MM-DD format) cause parsing errors
- Very large date ranges may time out or return partial data

## How this service works

Historical weather API by coordinates and date range: daily high/low temperature and total precipitation for any past date range at any latitude/longitude worldwide, back to 1940. Structured JSON for backtesting, insurance, agriculture, and research agents.

## Output

Structured JSON containing daily weather records for the requested coordinate and date range, including daily high temperature, daily low temperature, and total precipitation for each day from start_date to end_date.
