FSR API
The Flightsimradar API is here to help you get flight data. You can use it to look up telemetry data or access our lists of airports and airlines for your own application.
Please note that access to our api is not public and tokens are given to you on a request via our Discord ticket system.
Authentication
Headers & Permissions
The FSR API provides direct access to our enriched telemetry and reference data for airports, airlines, and countries. Note: For raw traffic feeds from external networks such as VATSIM or IVAO, please consult their respective API documentation.
To prevent abuse and ensure stability, all FSR endpoints are protected. You must include your personal API token in the request headers using thex-api-key field. Requests missing a valid header will be rejected with a 401 Unauthorized response.

Retrieve flight and route data
/api/radar/aircraft/[id]Retrieve current telemetry for a single active flight using a Callsign or network CID. The response merges data feeds and calculates real-time ETA, distance remaining, and aircraft photo URLs.
/api/radar/tracks/[callsign]Fetch the coordinate history (breadcrumbs) of a specific active flight. Used primarily for rendering accurate flight paths on a map interface.
/api/radar/simbrief/[query]Lookup a user's active SimBrief dispatch. We parse the raw XML/JSON output and format it into the standard FSR route structure.
/api/radar/historyQuery the FSR database for past flight logs. Pass parameters in the request body to filter results by CID, Callsign, or specific date ranges.
Reference Data
Get thousands of airports, airlines and countries used by FSR
/api/radar/data/airportsReturns our maintained airport dictionary. Includes ICAO/IATA codes, full names, coordinates, elevation, and timezone mapping for global hubs and military bases.
/api/radar/data/airlinesReturns our callsign dictionary. Use this to translate 3-letter ICAO prefixes into real-world airlines, virtual airlines, or specific military designations.
/api/radar/data/countriesReturns ISO-3166-1 alpha-2 country codes and a timezone-to-country reference map. Useful for rendering regional flags or localizing time data.
Rate Limits
To guarantee server stability, standard API tokens are restricted to a maximum of 60 requests per minute. Exceeding this threshold will trigger a temporary 429 Too Many Requests response.
Request API Access
Access is strictly managed. Join our Discord server and come in contact with the development team by opening a ticket in the 'request-support' channel where you can state your description of what you intend to build using the FSR api data.
