# RunwayOracle KSEA Seattle-Tacoma Runway Temperature Nowcast

> RunwayOracle KSEA Seattle-Tacoma Runway Temperature Nowcast is a paid API for AI agents from runwayoracle.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a calibrated runway-temperature basis nowcast for Seattle-Tacoma International Airport (KSEA) with optional strike probability estimates using live 3-hour thermal-memory telemetry.

## 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-ksea-seattle-tacoma-runway-temperature-nowcast-031561e1
```

Example prompt: What's the current runway temperature nowcast for Seattle-Tacoma International, and what's the probability it's above 35 degrees Fahrenheit right now?

## When to prefer this

Use this endpoint when you need a real-time, calibrated runway surface temperature estimate specifically for Seattle-Tacoma International (KSEA), especially when you need strike probabilities for a target temperature threshold — such as for weather derivative pricing, aviation operations planning, or pavement condition assessments. Prefer the $0.05 tier for the most accurate nowcast (RMSE 1.12°F) with live thermal-memory telemetry.

## Known failure modes

- Payment not received or invalid — returns 402 with fallback degraded mode (RMSE 2.11F) for $0.01
- Telemetry unavailable — falls back to degraded model without live 3h thermal-memory
- Invalid strikeF parameter (outside -80..140°F range) — likely returns 400 or ignores parameter
- Service unavailable or timeout — no data returned

## How this service works

Seattle weather forecast API: live temperature nowcast and daily high forecast for Seattle-Tacoma Intl (KSEA), with calibrated probability the temperature ends above/below any Fahrenheit strike. KSEA is the official settlement station for Kalshi KXHIGHTSEA daily high temperature prediction markets. 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 1.22F); $0.01 degraded fallback (RMSE 2.69F). Free catalog: https://runwayoracle.com/catalog.json. Model-conditional estimates; not financial advice.

## Output

Returns a calibrated runway-temperature basis nowcast for KSEA with an OOS RMSE of 1.12°F (live) or 2.11°F (degraded fallback), and optionally includes calibrated P(above) and P(below) strike probabilities for a user-specified temperature in degrees Fahrenheit.
