DeepSeek has released Search API and Fetch API to give agents and RAG applications live web access. The Search API returns structured results from DeepSeek's in-house engine, while Fetch API retrieves single pages as Markdown. Both use the same bearer token authentication as the core DeepSeek API at https://api.deepseek.com.
Pricing is set at $0.75 per 1,000 successful requests. Search supports query operators like `site:`, `-site:`, `lang:`, `after:`, and `before:` for precise filtering. Requests accept `query` (1–128 chars), `count` (1–50, default 10), `need_content` (boolean), and optional `ori_question` and `localization` fields.
Responses include `rerank_score`, `title`, `url`, `snippet`, `summary`, full `content` when requested, and `site_name`/`site_icon`. A Python example shows a search for "Deep Seek V4 release" returning five results with summaries. The APIs are designed for developers building autonomous agents that need real-time, citeable web data.
