How this service works
DuckDuckGo: Scrape DuckDuckGo search results in JSON format automatically, using custom parameters. Structured JSON, USD 0.05 per call in USDC — no API key, no account, no subscription, no minimum. Not affiliated with, endorsed by or an official channel of any of the services the results come from. All trademarks and copyright remain the property of their respective owners.
Output
Returns a structured JSON object containing DuckDuckGo search results including page titles, URLs, snippets, and optionally an AI Search Assist response. Supports paginated results via offset and can include region-specific and date-filtered results.
Example use cases
Competitive research via fresh results
“Search DuckDuckGo for 'OpenAI competitors 2024', filter to the past week, using US English region, and return the structured results so I can see what's trending.”
Regional search for local market data
“Can you run a DuckDuckGo search for 'electric vehicle incentives' in the UK English region and pull back the results as JSON? I need to compare what's showing up there.”
Brand monitoring with safe search off
“Search DuckDuckGo for 'AcmeCorp reviews' with adult content filtering off, date range set to the past month, and give me the first page of results in structured JSON format.”
Technical details
Endpoint
POSThttps://serp402.com/api/v1/duckduckgo-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need DuckDuckGo-specific SERP data in structured JSON format without signing up for an account or managing API keys, especially when privacy-focused search results, regional targeting, or date-filtered results are important. It is ideal for pay-per-use agent workflows where you want to avoid subscription commitments. Prefer this over Google-based SERP APIs when you want DuckDuckGo's index and ranking specifically.
Side effects
- Invalid or missing query parameter returns an error
- Unsupported region code (kl) may return no results or default to global
- Combining search_assist=true with monthly date filter (m) is not allowed and will fail
- Payment failure or insufficient USDC balance prevents the call
- Rate limiting or DuckDuckGo-side blocking may return empty or partial results
- Invalid safe search value returns an error
