# NDW Emission Zones API

> NDW Emission Zones API is a paid API for AI agents from api.getapi.nl, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns geographic boundaries and vehicle restrictions for zero-emission zones (ZEZ) in the Netherlands, sourced from NDW (Nationale Databank Wegverkeersgegevens).

## Facts

- Endpoint: GET https://api.getapi.nl/api/v1/ndw/emissiezones
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/ndw-emission-zones-api-5b43f6d6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_WuhnUqhtGogkFfRx6Bb1A

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ndw-emission-zones-api-5b43f6d6
```

Example prompt: Can you get me the current zero emission zones in the Netherlands, including the polygon boundaries and vehicle restrictions like which fuel types and emission classes are banned?

## When to prefer this

Use this endpoint when you need structured, machine-readable data about Dutch emission zones including precise polygon geometries and vehicle restriction details. Prefer it over general mapping APIs when you need regulation-level specificity (fuel type, emission class) tied to geographic boundaries in the Netherlands. Ideal for logistics routing, fleet compliance checking, or building regulatory maps of Dutch urban areas.

## Known failure modes

- No zones found for the requested filter — returns empty results array
- Invalid query parameters — 400 Bad Request
- Payment not provided or insufficient — 402 Payment Required
- Service unavailable or NDW upstream down — 503 error
- Rate limit exceeded — 429 Too Many Requests

## Output

Returns a JSON object with a total count and a results array. Each result includes a zone ID, city name, zone name, GeoJSON polygon geometry (coordinates array), zone type (e.g. zero_emission), valid_from and valid_until timestamps, and an array of vehicle restrictions specifying fuel type, vehicle type, and emission class combinations that are restricted within the zone.
