// Key points

  • The Search and Fetch endpoints run on DeepSeek's in-house search engine, which it says serves hundreds of millions of requests a day worldwide.
  • Each endpoint costs $0.75 per 1,000 calls.
  • Search and Fetch calls made through server-side tools in DeepSeek Harness, Claude Code and Codex are free for DeepSeek API users until billing starts on October 31, 2026 at 16:00 UTC.
  • V4.1-Flash-1017 went live the same day on the website, app and API, optimized for DeepSeek Harness, Tencent CodeBuddy, WorkBuddy and others; DeepSeek recommends DeepSeek Harness v0.2.1-rc.1 or later.

Builder's takeAgent web access now has a plainly priced option from a Chinese provider. For a content backend that looks things up, like PandaClaws, use the free window before October 31 to compare hit rate and latency against your current search; before adopting it, count searches per task, because that number runs away easily in agents.
