API keys & access

Company.info APIs use API keys to authenticate requests. Include your API key in the X-API-Key header of every request.

X-API-Key: YOUR_API_KEY

Obtain an API key

During onboarding, an API key is provided to your designated technical contact. If you need a key or have questions about your access, contact Company.info.

Use your API key

curl --request GET \
  --url 'https://api.company.info/{endpoint}' \
  --header 'X-API-Key: YOUR_API_KEY'

Keep your API key confidential. Do not include it in public repositories, client-side applications, or publicly accessible logs.

API access

The APIs available to your key depend on your access configuration. If a request returns 403 Key not authorized, check that you are using the intended key and contact Company.info if the issue persists.

Trial keys and usage quota

A Trial key provides access to selected Company.info APIs for eight weeks, with a fixed allowance of 750 API calls.

The allowance applies to the full Trial period. It is not a daily allowance and does not reset each day.

Each API has its own dedicated allowance. Unused calls for one API cannot be transferred to another API.

API	Trial allowance
NL Organization Search + Profile	350 calls, shared
NL Locations	50 calls
Compliance Screening	50 calls
NL Official Documents	20 calls
Compliance Monitoring	50 calls
NL Monitoring	75 calls
Routeplanner Map	50 calls
Routeplanner Geo	50 calls
Routeplanner Routing	50 calls
UBO Investigation	5 calls reserved*

* UBO Investigation is not yet available in the Trial.

Important notes

NL Organization Search and NL Organization Profile share one combined allowance of 350 calls.
One NL Official Documents requires two API calls. The 20-call allowance supports up to 10 extracts.
Integrations should handle 429 Too Many Requests responses by temporarily reducing the request rate.

Rate limiting

API usage may be subject to rate limits to maintain platform availability and performance. If you receive 429 Too Many Requests, reduce your request rate and retry after a short delay. Avoid immediate or unlimited retries.

Troubleshooting

Response	What to check
`401`	Verify that the `X-API-Key` header is present and contains the correct key.
`403`	Verify that the key is intended for the requested API. Contact Company.info if the issue persists.
`429`	Reduce the request rate and retry after a short delay.

How to obtain an API Key

As part of onboarding, we identify a designated technical contact. Once onboarding is complete, this contact will receive the API key by email.
