**Category:** Business Directories | **Website:** [kvk.nl/](https://kvk.nl/) | **Docs:** [parse.bot/marketplace/fe1ac0fe-955e-42db-92eb-2f4639117b25/kvk-nl-api](https://parse.bot/marketplace/fe1ac0fe-955e-42db-92eb-2f4639117b25/kvk-nl-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/kvk/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get business

Look up a specific business by its KVK number. Returns all registration entries (vestigingen and rechtspersoon) associated with that number. A business may have multiple entries when it has branch offices.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `kvk_nummer` | string | Yes | 8-digit KVK registration number (e.g. 52185532). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/kvk/get-business \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"kvk_nummer":"<string>"}'
```

### Search businesses

Full-text search across the KVK Handelsregister (Dutch trade register). Matches business names, KVK numbers, addresses, and keywords. Returns paginated results filtered to currently registered (ingeschreven) businesses. Each result includes registration details, legal form, address, and activity description.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for pagination (1-based). |
| `page_size` | integer | No | Number of results per page (1-50). |
| `query` | string | Yes | Search term: business name, KVK number, address, or keyword. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/kvk/search-businesses \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"page":"<integer>","page_size":"<integer>","query":"<string>"}'
