API Documentation

The METAR & TAF Decoder API lets you retrieve and decode METAR weather reports and TAF forecasts programmatically.

Base URL

All endpoints are relative to the following base URL:

https://api.metar-taf-decoder.com

Authentication

Public endpoints can be called without authentication but are subject to IP-based rate limiting. To get higher rate limits, register for an account, generate an API key from the API Keys page, and include it in your requests using the following header:

X-API-Key: your-api-key

Language

Decoded field values (e.g. wind directions, cloud descriptions) can be returned in English or French. Set the Accept-Language header to en or fr.

Accept-Language: en
Accept-Language: fr

Rate Limits

Unauthenticated requests are rate-limited per IP address. Authenticated requests using a valid API key have higher limits.
