DeepSeek近日发布了Search API和Fetch API两项新服务，为AI智能体和RAG应用提供实时网络内容访问能力。1这两项服务均基于DeepSeek内部搜索引擎构建，其中Search API支持查询网页并返回结构化结果，Fetch API可获取单个网页内容。1
两项服务的定价相同，均为每1000次成功请求0.75美元。1只有HTTP 200响应且返回实际结果的请求才会计费，失败请求、空结果和超时情况均不产生费用。1目前通过DeepSeek Harness、Claude Code或Codex使用的服务端工具调用仍然免费，但从2026年11月1日00:00（北京时间）起将开始按请求计费。1在账户层面，Search和Fetch两项API拥有独立的QPS（每秒查询数）限制，彼此不占用配额。1
DeepSeek has introduced two new API services designed to enable AI agents and retrieval-augmented generation (RAG) applications to access live web content.1 The Search API allows users to query web pages and receive structured results, while the Fetch API retrieves the content of individual web pages.1 Both services are priced at $0.75 per 1,000 successful requests.1
The APIs are built on DeepSeek's internal search engine infrastructure.1 Billing applies only to requests that return HTTP 200 status and actual results; failed requests, empty responses, and timeouts are not charged.1 Currently, server-side tool calls made through DeepSeek Harness, Claude Code, or Codex are offered free of charge, but will begin incurring per-request fees starting November 1, 2026, at 00:00 Beijing time.1 The Search and Fetch APIs maintain independent quota allocations at the account level and do not compete for the same resource limits.1
