What you get

Everything for a smart pre-purchase check.

Every Dutch plate lookup pulls free RDW data and runs it through our tax engine — no account, no credit card, every time.

Free RDW Tier-0 data

Make, model, body, colour, registration date, engine cc, kerb weight, fuel, emission class, catalogusprijs, bruto BPM. All from opendata.rdw.nl, CC-0 licensed.

APK, recall & odometer

MOT expiry + status (valid / expiring / expired), open recall flag, and the official RDW tellerstandoordeel odometer plausibility judgement.

Vehicle tax engine

Every vehicle gets its bijtelling status — EV reduced rate, PHEV, youngtimer dagwaarde, or standard 22%. Immediate 2027 projection: which rates change and what does it cost you?

Decision trace

The tax engine traverses a versioned JSON rule graph. Every report carries the full node-by-node path — auditable, reproducible, and the pivot between deterministic and RAG reasoning.

Full history (coming)

Mileage history, damage records, owner count, and current valuation — unlocked per-report via iDEAL. Sourced from RDW licensed data + carVertical/autoDNA.

REST + MCP API

Agent-native from day one. Every capability is a REST endpoint and an MCP tool. Your buying assistant, dealer bot, or fleet manager can pull reports autonomously.

Tax intelligence

Graph-driven.
Deterministic.
Auditable.

The tax engine traverses a versioned JSON rule graph — not if-else chains. EV, PHEV, youngtimer, conventional: same input → same path → same outcome → same explanation.

  • EV 17% bijtelling until 2027, then standard 22% — PHEV already at 22%
  • Youngtimer threshold: 15yr in 2025 → 16 in 2026 → 25 from 1 Jan 2027
  • Rule version stamped on every report — results are reproducible and diff-able
  • Open-ended tax questions routed to RAG; graph engine answers the structured ones
