# BizIntel API – Historical Weather by Coordinates

> BizIntel API – Historical Weather by Coordinates is a paid API for AI agents from bizintel-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns historical daily max/min temperatures for a given latitude, longitude, and past date.

## Facts

- Endpoint: POST https://bizintel-api.hahavoid0.workers.dev/geography/weather-history
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/bizintel-api-historical-weather-by-coordinates-0ad22204
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_JRou2O5qOChXWxkcqN1vP

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 bizintel-api-historical-weather-by-coordinates-0ad22204 -d '<json body>'
```

Example prompt: What were the high and low temperatures at latitude 48.8566, longitude 2.3522 on 2023-07-15?

## When to prefer this

Choose this endpoint when you need a quick point-in-time historical daily temperature lookup for a specific latitude/longitude and date, without needing a full weather history API subscription or API key. It is well-suited for one-off lookups billed per call at $0.02 USDC, making it cost-effective for sparse queries. Prefer alternatives if you need bulk historical data, hourly resolution, or non-temperature weather variables like precipitation or wind.

## Known failure modes

- Date is in the future — endpoint requires a past date in YYYY-MM-DD format
- Coordinates are invalid or out of range — latitude must be -90 to 90, longitude -180 to 180
- Location not covered — supported field returns false with possible warnings
- Malformed request body — missing required fields returns a schema validation error
- Payment failure — x402 USDC payment on Base not completed, request rejected

## How this service works

Queries historical temperature observations for a coordinate and date.

## Output

A JSON object containing max_temp and min_temp for the requested date and location, a supported flag indicating whether the location/date combination is covered, a confidence rating (e.g. 'high'), a data_as_of field showing data freshness, any warnings, and a disclaimer. Temperatures are numeric values (degrees, likely Celsius).
