What teams build with it

Company context wherever an IP shows up

Product teams, data teams and growth engineers use the Reveal API to add company intelligence to the tools they already run.

Identify visitors inside your product

Show your own users which companies visit their websites or apps, as a native feature of your platform.

Enrich signups and form fills

Add company, size and industry to every signup before it reaches your CRM, and keep your forms short.

Personalize your website

Change headlines, case studies and calls to action by industry or company size on the very first page view.

Power pipelines and AI agents

Resolve IPs in server logs, warehouses and agent workflows to give every event and every prompt company context.

How it works

Live in an afternoon, not a quarter

A single GET endpoint, clear status codes and a staging environment to build against.

Get your API key

Tell us your use case and expected volume. We set up a key with a quota that fits.

Send an IPv4 address

Call GET /company/{ip} with your key in the Authorization header.

Act on the response

Store the company profile, route the lead or personalize the page. No match returns a clean 204.

200	Company found, profile returned as JSON
204	No company matched this IP
400	Invalid format or IPv6 address
401	Missing or invalid API key
429	Request or identification quota reached

FAQs

Frequently Asked Questions

How do I get an API key?

The Reveal API is available on the Organisation plan or as a standalone data product. Tell our team your use case and expected volume and we'll set up a key with the right quota, usually within a day.

What happens when an IP can't be matched?

The API returns HTTP 204 with no body, so your code can fall back gracefully. Residential and mobile connections often don't resolve to a company.

Does the API support IPv6?

Not yet. Reveal resolves IPv4 addresses today and returns a clear 400 error for IPv6 input. IPv6 support is in development.

Are there rate limits?

Each key has a request and identification quota based on your plan. If you go over it, the API responds with HTTP 429 so you can back off and retry.

Is there a test environment?

Yes. The API docs include a separate staging environment and a ready-made Postman collection, so you can build and test before you go live.

Is the API GDPR compliant?

Yes. Reveal returns company-level firmographic data only. It identifies organisations, never individual people, and Albacross is built in Stockholm for GDPR and CCPA.
