## 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 weather-oracle-api-probabilistic-max-temperature-forecast-sbgr-s-o-52035ceb
```

Example prompt: What's the probabilistic max-temperature forecast for São Paulo Guarulhos (SBGR) for tomorrow — give me the p05, p50, and p95 values in Celsius?

## When to prefer this

Choose this endpoint when you need a calibrated, probabilistic (percentile-based) daily maximum-temperature forecast for one of the 51 cities covered by Polymarket weather markets — especially for prediction market trading, risk-weighted decisions, or any use case where knowing the spread (p05–p95) matters more than a single-point forecast. Prefer it over generic weather APIs when you need ensemble bias correction, per-station historical baselines, and pay-as-you-go pricing with no account setup.

## Known failure modes

- Invalid or unsupported ICAO station code returns an error (only 51 Polymarket-covered cities are supported)
- Date outside today/tomorrow range may return an error or be ignored
- Payment failure or insufficient USDC balance on Base results in 402 Payment Required
- Network or server unavailability at the sslip.io host returns a 5xx error
- Malformed date format (not YYYY-MM-DD) causes a validation error

## How this service works

Probabilistic daily max-temperature forecasts for the 51 cities behind Polymarket weather markets. Multi-model ensemble with per-model seasonal bias correction, refreshed hourly. Pay per request in USDC on Base via x402 — no accounts, no API keys.

## Output

A JSON object containing the ICAO station code, the target month's temperature percentiles (p05, p50, p95 in °C), the number of historical days in the sample, monthly record max and min temperatures, and the all-time station record high — all derived from a multi-model ensemble with per-model seasonal bias correction, refreshed hourly.
