## 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 runwayoracle-ord-edge-chicago-o-hare-runway-temperature-nowcast-f9fb7050
```

Example prompt: What's the current runway pavement temperature nowcast at Chicago O'Hare (KORD), and what's the probability it's above 32°F?

## When to prefer this

Choose this endpoint when you need a real-time, high-accuracy runway pavement temperature estimate specifically for Chicago O'Hare (KORD), especially when you also want calibrated probability that temperature is above or below a specific strike threshold. Prefer this over generic weather APIs when precision surface temperature (not air temperature) and calibrated uncertainty estimates matter, such as for aviation operations, derivative pricing, or de-icing decision support.

## Known failure modes

- Live telemetry unavailable — falls back to degraded model (OOS RMSE 1.62°F) at reduced cost ($0.01)
- strikeF parameter out of range (-80..140°F) — likely rejected or ignored
- Payment not received — x402 payment required before response is returned
- Network or upstream sensor outage — no nowcast available

## How this service works

Chicago weather forecast API: live temperature nowcast and daily high forecast for Chicago O'Hare (KORD), with calibrated probability the temperature ends above/below any Fahrenheit strike. Built for AI agents trading weather prediction markets or needing real-time weather data. $0.05 with live 3h thermal-memory telemetry (out-of-sample nowcast RMSE 1.04F); $0.01 degraded fallback (RMSE 1.37F). Free catalog: https://runwayoracle.com/catalog.json. Model-conditional estimates; not financial advice.

## Output

Returns a calibrated runway surface temperature nowcast for KORD using live 3-hour thermal-memory telemetry (out-of-sample RMSE ~1.07°F). If a strikeF query parameter is supplied, also returns model-calibrated P(above strike) and P(below strike) probabilities. Falls back to a degraded model (RMSE ~1.62°F) if live telemetry is unavailable.
