Every Deepinfo API endpoint as a Postman collection. Download it with the Production environment, add your API key and send requests.

---
Every endpoint of the [API Reference](/reference/) is in the Deepinfo Postman collection, in the same
modules and groups as on this site, with its parameters, request bodies and descriptions. Download the
collection and the Production environment, add your API key and send your first request in a few minutes.

## Set It Up

1. Download both files with the buttons above.
2. In Postman, choose **Import** and drop both files.
3. Select the **Deepinfo - Production** environment in Postman's environment menu.
4. Put your API key in that environment's `api_key` variable, in **Current value**, so it stays on your
   machine. No key yet? See [Get an API Key](/getting-started/authentication/#get-an-api-key).
5. Open a request, for example **Lookup › Domain WHOIS**, and select **Send**.

Authentication is set once on the collection (**Authorization** tab, *API Key*): every request sends your
key in the `apikey` header, so you never add it by hand.

## Variables

Every URL in the collection starts with `{{api_base_url}}/{{api_version}}`, so the host and the version
come from the selected environment.

| Variable | Value | Description |
|---|---|---|
| `api_base_url` | `https://api.deepinfo.com` | API host, without `/v1` |
| `api_version` | `v1` | API version, the first path segment of every endpoint |
| `api_key` | *your key* | Sent in the `apikey` header of every request |

The three variables are defined on the collection (defaults) and in the environment. The environment
wins, so keep your key there.

## Demo Accounts

With a demo account, set `api_base_url` to `https://api.deepinfodemo.com` in your environment. A copy of
the environment named Demo lets you keep both. See
[Environments & Base URL](/getting-started/environments-and-base-url/).

## What It Contains

- **Every request of the API Reference**, with its query and path parameters and, for searches and other
  `POST` requests, a request body to start from. [Search & Filters](/getting-started/search-and-filters/)
  explains the filter format.
- **Two checks after every request:** the response must not be a server error, and a 401 is reported as a
  missing API key. The `deepinfo-request-id` header of the last response is kept in the
  `last_request_id` collection variable: include it when you contact
  [support@deepinfo.com](mailto:support@deepinfo.com).
- **The requests behind the error examples** of [Errors](/getting-started/errors/), in the
  **Getting Started › Errors** folder.
- **No saved example responses.** Each endpoint's page on this site shows its example responses, and in
  Postman you see your own data.

## Updates

The collection is built from the same source as this site, so it changes when the reference does.
Download it again to get new endpoints and changes; the [Changelog](/changelog/) lists them.
