De Lijn Zoek Open Data Services

API change history

This set includes Search Services

  • Search stops by description. Eg Veemarkt or station.
  • Search lines by number or description. Eg search line 48 or Hamont
  • Search locations (x,y) by user adress input. Typical for input on a routeplanner (eg kerkstraat 14 Hasselt or Achter De Kazerne ) . Limitied Geocoding service that retuns stops, adresses or POIs and its XY coordinates

Some more explanation can be found here

De Lijn does apply limits to its open data.
On request and when justified we can increase these limits per subscription

  • Max 864000 calls per product per day
  • Max 6000 calls per product per minute
  • We have some more non disclosed meassures to ensure API stability
  • We do not provide SLAs.
  • Data quality The quality of the data that is disclosed is equal to the quality that is sufficient for internal use of the data (within the services of the Flemish or local government).
