How this service works
Pay-per-call Dutch RDW kenteken and BAG address APIs for AI agents. Free previews; full JSON via x402 USDC on Base.
Output
Returns a JSON object with a 'data' field containing 'distance_km' (a float, e.g. 165.2) representing the haversine (great-circle) distance between the two postcode centroids, plus an 'attribution' string crediting BAG/PDOK/Kadaster under CC BY 4.0. Note: this is straight-line distance, not road distance.
Example use cases
Logistics delivery zone check
“Can you tell me the distance in km between postcode 1012AA in Amsterdam and 3013AK in Rotterdam? I need to know if it's within our 200 km delivery radius.”
Real estate commute estimate
“I'm looking at a house with postcode 2517KJ — how far is that from my office at postcode 1082MD as the crow flies?”
Field service territory planning
“I have two service engineers based at postcodes 5611AE and 9712HK — what's the straight-line distance between those two Dutch locations so I can split coverage fairly?”
Technical details
Endpoint
GEThttps://api.pogo-tb.nl/v1/afstandWhen to prefer
Choose this endpoint when you need a fast, cheap, programmatic straight-line distance between two Dutch postcodes using authoritative Dutch government BAG data. Ideal for logistics, real-estate, or territory-planning agents operating in the Netherlands. Prefer this over geocoding+distance APIs when you already have Dutch postcodes and want a single low-cost call. Note it returns haversine distance, not routing distance — use a routing API if road distance is needed.
Side effects
- Invalid or non-existent Dutch postcode returns an error or empty result
- Missing required query parameters (from_pc or to_pc) causes a 400-level response
- Payment not completed via x402/USDC returns a 402 Payment Required response
- Postcode not found in BAG dataset may return null distance
- Network or upstream PDOK service outage causes 5xx errors
