It operates the public Instant Answer API at api.duckduckgo.com (free, JSON/XML), the Duck.ai anonymous AI-chat proxy at duck.ai (routes to Anthropic Claude, OpenAI GPT, Meta Llama, Mistral models without storing or training on prompts), the Tracker Radar open dataset (CC BY-NC-SA), Email Protection (@duck.com forwarding addresses), and Privacy Pro (VPN + Personal Information Removal + Identity Theft Restoration). image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Search - Privacy - Browser - AI Chat - Email Protection - VPN - Trackers - Identity created: '2026-05-23' modified: '2026-05-23' specificationVersion: '0.19' apis: - aid: duckduckgo:instant-answer-api name: DuckDuckGo Instant Answer API humanURL: https://duckduckgo.com/api baseURL: https://api.duckduckgo.com tags: - Search - Instant Answer - Public API - Free description: >- The DuckDuckGo Instant Answer API returns the boxed answer that appears above DuckDuckGo search results - topic summaries (largely sourced from Wikipedia / structured sites), definitions, categories, disambiguations, and !bang redirects. It is a free, key-less GET endpoint that returns JSON (default), JSON-P (via callback) or XML. It does not return the DuckDuckGo search-results listing itself; it returns only zero-click / instant-answer payloads (Abstract, Answer, Definition, RelatedTopics, Results, Redirect for bangs, plus Image/Heading/Type metadata).

Duck.ai Plus adds GPT-4o, GPT-5.2, Claude Sonnet 4.5, Llama 4 Maverick. Duck.ai Pro adds Claude Opus 4.6, higher reasoning effort and 2x usage limits.
