Input rules & validation notes

  • address is optional for this service. You can send one complete address string and Didit will split it into structured address elements when possible, or you can send the structured fields explicitly.
  • address_element_1 is the street address, including street number and street type.
  • address_element_2 is optional unit, building, floor, or extra address line. Didit only sends it when you provide it explicitly.
  • address_element_3 is suburb, district, locality, or neighborhood.
  • address_element_4 is city, town, state, province, or region.
  • address_element_5 is postcode or postal code. postal_code is accepted as an alias.
  • Address-based database services need at least address_element_1 plus one searchable component such as address_element_3, address_element_4, or address_element_5; requests rejected before source lookup are not charged.

Returned data

The exact fields surfaced in source_data depend on what the registry returns. The generated example for nld_consumer currently documents this normalized shape:
  • date_of_birth
  • first_name
  • full_name
  • last_name
  • name_match_score

​
Pricing & SLAs

Netherlands Consumer queries are billed only when Didit receives a conclusive result from the validation source.
  • Per-call price: $0.08 USD.
  • Billing: per successful query. You are not charged when the registry is unreachable, when required fields are missing, or when the request is rejected before reaching the source.
  • Latency: typical p95 < 2 s.
  • Availability: 99.9% per quarter on Didit’s side; downstream source availability varies by country and dataset.
