DuckDuckGo

SERP API DuckDuckGo Query Parameters

Configure DuckDuckGo search queries using Thordata's SERP API, including output options for geographical location and pagination parameters.

q ,Search Query(Required)

Define the search query used for data crawling (default value: q=pizza). Any keywords in any language are supported.

Example Request:

Example with q:pizza parameter

curl -X POST https://scraperapi.thordata.com/request \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Authorization: Bearer token" \
 -d "engine=duckduckgo" \
 -d "q=pizza" \
 -d "json=1"

Geographical Location

kl ,Location(Optional)

Specify the interface language and region for search results (e.g., "zh-cn"

provides a Simplified Chinese interface and prioritizes displaying results from the China region).

Example Request:

Example results for q : pizza,kl:japan

curl -X POST https://scraperapi.thordata.com/request \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Authorization: Bearer token" \
 -d "engine=duckduckgo" \
 -d "q=pizza" \
 -d "json=1" \
 -d "kl=Japan"

Pagination

start ,Result offset(Optional)

Set the starting point for search result pagination (e.g., "start=30" means skipping the first 30 results and starting to display from the 31st result). Rules:

• start=30 → Skips first 30 results (page 2)

• Max: start=500 (result quality declines after ~16 pages)

Example Request:

Example results for q : pizza,start:2

curl -X POST https://scraperapi.thordata.com/request \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Authorization: Bearer token" \
 -d "engine=duckduckgo" \
 -d "q=pizza" \
 -d "json=1" \
 -d "start=2"

Advanced Filters

df ,Filter By Date(Optional)

Filter search results by time range ('d = past 24 hours', 'w = past week', 'm = past month').

Filters results by time range:

Value	Time Range	Use Case
d	Last 24 hours	Time-sensitive queries
w	Last 1 week	Balanced freshness/coverage
m	Last 1 month	Default range
y	Last 1 year	Historical data

Example Request:

Example results for q : pizza,df:y

curl -X POST https://scraperapi.thordata.com/request \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Authorization: Bearer token" \
 -d "engine=duckduckgo" \
 -d "q=pizza" \
 -d "json=1" \
 -d "df=y"

kp ,Safe(Optional)

Set the search content safety filtering level (Strict / Moderate / Disabled) to filter sensitive information such as adult content, violence, etc.

Safe search filtering:

• kp=-2: Strict (default)

• kp=-1: Moderate

• kp=1: Disabled (may trigger CAPTCHA)

Example Request:

Example results for q : pizza,kp:1

curl -X POST https://scraperapi.thordata.com/request \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Authorization: Bearer token" \
 -d "engine=duckduckgo" \
 -d "q=pizza" \
 -d "json=1" \
 -d "kp=1"
