Welcome to the new Captain Data API v1, which allows you to get qualified, fresh and high-quality data about people and companies. If you encounter any issues using this API, feel free to reach out at support@captaindata.com.
If you already used Captain Data in the past, you may find this API much simpler and easier to use. It directly and instantly fetches the data you need, without the need to create and manage complex workflows. You just need a new Captain Data account, and can start using the API right away.

Authentication

To authorize requests, you need to add the following header X-API-Key: <your_api_key> to all API requests (case insensitive). Here’s an example of a request to the API:
curl --location 'https://api.captaindata.com/v1/quotas' \
--header 'X-API-Key: <your_api_key>'
All subsequent examples will use this header as part of the request. To get your API Key, go to Developer Settings and copy the appropriate values.
Each user of your workspace has their own unique API Key that is tied to their account. API Keys are not shared across the workspace.

Playground

Each API endpoint has an interactive playground where you can test requests directly.

Pagination

Some endpoints return paginated results. To handle pagination the best possible way, we’ve got you covered with a simple and efficient mechanism and a full guide to explain it in the Handle Pagination documentation.

Rate Limits

The API is rate limited to manage the load on our servers. You can find detailed information about the rate limits in the Rate Limits documentation.
