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.
