Background & analysis
On October 17, 2026, DeepSeek announced that its Search and Fetch APIs were officially live. Both interfaces run on DeepSeek's in-house search engine and are aimed at Agent and RAG applications that need real-time web content. Search takes a query, searches the web and returns structured results, while Fetch retrieves a single page and returns its title and body as Markdown. Both are raw JSON APIs with a Base URL of api.deepseek.com.
The same day, DeepSeek swapped out the model behind its deepseek-flash API endpoint. The new checkpoint, DeepSeek-V4.1-Flash-1017, was published on Hugging Face under the MIT license, with the endpoint's name and price left unchanged. According to a DEV Community article, DeepSeek described the change as a minor update, yet all 11 benchmarks it published moved up, including a gain of 11.1 points on Terminal-Bench 4.0. The article's author said they could not reproduce DeepSWE and only checked the configuration and cache data.
On October 18, DeepSeek published a notice stating that its API now supports web search and fetching, billed by the number of successful requests at 5 yuan per 1,000 calls. The notice said that when users call the DeepSeek API from DeepSeek Harness, Claude Code or Codex, those tools already reach the Search and Fetch interfaces through server-side tool calls. Such calls are currently not billed, and per-call charges will begin at 00:00 Beijing time on November 1, 2026. Public information currently stops at this billing arrangement.
