# DuckDuckGo SERP API

The DuckDuckGo SERP API provides real-time access to structured DuckDuckGo search results, offering no blocks or CAPTCHAs.

## Get Your API Key

Sign in at [hasdata.com](https://app.hasdata.com/sign-in), go to your account settings, and copy your API key.
All requests must include your key in the `x-api-key` header.

## Request Cost and API Credits

Each request to the DuckDuckGo SERP API consumes **API Credits** from your account balance.

* **Cost per request:** 10 API Credits
* Credits are deducted only for successful requests.
* Your total available credits depend on your active plan.

<Tip>You can use your credits across all HasData APIs. The same credit balance is shared platform-wide.</Tip>
<Warning>**Unused credits do not roll over.** Any remaining credits expire at the end of the current billing period.</Warning>

To monitor your credit usage and remaining balance, sign in to your account dashboard at [app.hasdata.com](https://app.hasdata.com/sign-in).

## API Parameters

| Parameter       | Default Value | Required | Description                                                                                                                                                                                                                                                                                                       |
| --------------- | ------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `q`             | Coffee        | No       | Specify the search term for which you want to scrape the SERP. Required unless `nextPageToken` is provided (which carries the query of the page it continues).                                                                                                                                                    |
| `kl`            | -             | No       | DuckDuckGo region code in `<country>-<language>` form (e.g. `us-en`, `de-de`). Sets country and interface language at once; takes precedence over `cc`/`setLang`. Use `wt-wt` for no region.                                                                                                                      |
| `cc`            | -             | No       | The two-letter country code for the country to search from. Combined with `setLang` to form the DuckDuckGo region. Ignored if `kl` is set.                                                                                                                                                                        |
| `setLang`       | -             | No       | The preferred result/interface language code — usually two letters (e.g. `en`, `de`), with script-tag variants for some languages (e.g. `zh-hans`, `zh-hant`). Combined with `cc` to form the DuckDuckGo region. Ignored if `kl` is set.                                                                          |
| `safeSearch`    | -             | No       | Adult Content Filtering option.                                                                                                                                                                                                                                                                                   |
| `deviceType`    | desktop       | No       | Specify the device type for the search.                                                                                                                                                                                                                                                                           |
| `nextPageToken` | -             | No       | Opaque token returned in each response as `nextPageToken`. Pass it back (in place of `q`) to fetch the next page of results. It carries a pre-signed page URL bound to the original request's session, so it must be used as-is and cannot be constructed manually. Absent when there are no further pages.<br /> |
