- The search API finds web pages from query terms and returns titles, URLs, and summaries as structured results. According to the source, it uses DeepSeek's own search engine. - The fetch API takes one URL and converts the page body into Markdown text. The source notes that results may vary depending on the availability of the target site and its access policies. - According to the source's price list, search and fetch each cost 0.75 dollars per 1,000 successful requests. Requests that return empty results, fail, or time out are not charged. - According to the source, server-side tool calls made when using the API with DeepSeek Harness, Claude Code, or Codex are currently free, and per-request billing starts at midnight Beijing time on November 1, 2026. The account-level per-second request limits are 5 requests each for search and fetch.

O: This is useful for a developer who wants to connect an AI agent to up-to-date web information and tests a small-scale flow in which a search API finds candidates and a fetch API reads the page body only for results with a rerank_score of 1.5 or higher. X: The source says fetching is affected by the target site's access policies and per-domain requests-per-second limits. The free-tier guidance reflects the information at the time of reference, so costs after November 2026 should be checked separately.
