How can we help?

Radar gives you official public data (EU VAT register, central banks, customs tariffs, public DNS and more) as simple answers. You can try it in the browser, use it in your own software with one key, or ask us to do the data work for you.

No. Use the free tools at /tools for single checks, or the Services page: send us your file or task and we do it. The API key is for people who connect it to their own software.

The free plan gives 500 calls a month on every API, no card needed. The free tools in the browser are free too. Paid plans start at EUR 5 a month.

Write to us below from the same e-mail you signed up with (topic: Lost key). We send it again within one working day.

Open Account, paste your key and press Manage billing or cancel. The plan stays active to the end of the paid month. You can also write to us and we cancel it for you.

Yes. Enter your VAT ID at checkout and Stripe sends a receipt by e-mail. If you need a different invoice, write to us.

Yes, within 14 days of a payment if the service did not work for you. See the Refund policy.

A 502 error means the official source did not answer. It is not counted, so just try again a bit later. If it keeps failing, send us the API name and the input you used.

Most answers come in 1 to 3 seconds. APIs that read live web pages can take up to a minute, so use a timeout of 120 seconds.

No. We only count calls per key for billing. Your inputs and results are not stored after the answer is sent.

Yes. Import /v1/openapi.json as a custom GPT action, use our MCP servers, or ask us to set it up (service: Connect the data to your AI assistant).

Describe the task in two sentences. Within one working day you get a free sample of the result and an exact price. You pay only if you like it.

Often yes, if it is an official public source whose terms allow it. Choose the topic 'I need data you don't have yet' below and send the link.
