}Why Papi
Built for developers, priced for everyone.
Official BAG data
Addresses, postcodes and cities from the Dutch Registry of Addresses and Buildings (BAG) — the authoritative source.
Fast & scalable
Powered by OpenSearch for fast, fuzzy address search at nationwide scale.
One simple endpoint
A single REST call to search. Structured JSON back, with pagination. No SDK required, no fuss.
Secure access
Authenticate with JWT bearer tokens and clear per-subscription rate limits.
Fair pricing
Lower annual prices than comparable Dutch providers — plus a Lifetime option no one else offers.
Fully Dutch
Made for the Dutch market: NL coverage, NL + EN, VAT invoicing.
Pricing
Pick an annual plan, or pay once with Lifetime and use Papi forever.
Starter
1,000 lookups per month
100 requests/minute
Lifetime = pay once, use forever. No competitor offers this. It pays for itself in ~3 years — after that, it's free.
Growth
10,000 lookups per month
200 requests/minute
Lifetime = pay once, use forever. No competitor offers this. It pays for itself in ~3 years — after that, it's free.
Business

1,000 requests/minute
Lifetime = pay once, use forever. No competitor offers this. It pays for itself in ~2.6 years — after that, it's free.
Prices exclude 21% VAT. Final prices are confirmed in the portal's Plan catalog.
Papi vs. the rest
The same official BAG data — but with predictable pricing, NL + EN, and the only Lifetime licence on the market.
“Others” refers to typical Dutch address APIs; features vary by provider.
For developers
Three steps from zero to your first result.
-
1. Get a token
Create an account and grab an API token (JWT) with the address.search scope from the portal.
-
2. Call the API
A single POST to the search endpoint with your query.
-
3. Handle the result
You get structured, paginated address results back as JSON.
