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 x402-forgemesh-io-historical-weather-by-date-and-coordinates-6b7c598d -d '<json body>'
```

Example prompt: Can you look up the historical daily high and low temperatures and total precipitation for Houston (29.76, -95.36) from August 25 to September 1, 2017?

## When to prefer this

Use this endpoint when you need verified historical daily weather data (temperature highs/lows and precipitation) for a specific geographic coordinate and past date range. Ideal for post-event analysis, insurance claims verification, agricultural backtesting, or research requiring reanalysis model data back to 1940. Prefer this over forecast endpoints when the dates are in the past.

## Known failure modes

- Date out of supported historical range (pre-1940 or future dates) — likely returns an error or empty result
- Invalid latitude/longitude values — validation error
- Malformed date strings not matching YYYY-MM-DD format — parse error
- Date range too large — may time out or return error
- Payment failure — 402 response if USDC payment not processed

## How this service works

Daily high temperature, low temperature, and total precipitation for a given latitude/longitude across any past date range, sourced from a reanalysis weather model. Use for verifying what the weather was on a specific past date — event post-mortems, claims verification, or agricultural and research backtesting. Coverage back to 1940.

## Output

Daily records for each date in the requested range, each containing the high temperature, low temperature, and total precipitation for the given latitude/longitude, drawn from a reanalysis weather model with coverage back to 1940.
