DeepSeek opens its in-house search and fetch API

DeepSeek has opened the search engine behind its web and API search as a Search / Fetch API. In its update note, DeepSeek says the engine handles hundreds of millions of requests a day, indexes hundreds of billions of pages and supports multilingual search. Those figures are DeepSeek's own claims.

According to DeepSeek's API docs:

• Search and Fetch each cost $0.75 per 1,000 successful requests.
• A request is billable only if it returns HTTP 200 with a result. Failed requests, empty search results and timeouts are not billed.
• When the DeepSeek API is used through DeepSeek Harness, Claude Code or Codex, server-side tool calls already use these APIs. They are free for now, and per-request billing starts at 00:00 Beijing time on November 1, 2026.
