PacketStream Fetch API vs. DeepSeek Fetch API

At a glance

How they differ

How a page is read. PacketStream’s Fetch API downloads each page live through its residential network, from the United States or the country you choose, and follows up to five redirects. When a site answers 403, 429, or 503, it asks again from a different IP address. DeepSeek’s documentation does not say how its Fetch API reaches a page.

What you control. A PacketStream request can set the exit country, the User-Agent, main or full content, whether to keep links and images, how many characters to return, and where to start. DeepSeek’s Fetch API documents one field, the URL.

What comes back. PacketStream returns the content with the final URL after redirects, the site’s HTTP status, the page title and description, and the page’s total length, so your code knows when to read further. DeepSeek’s Fetch API returns a title and the content.

Search plus reading. The same PacketStream key and balance cover the Search API, which returns live Google results, and the MCP server, which gives Claude, Cursor, Codex CLI, and other clients both tools. For search, see PacketStream Search API vs. DeepSeek Search API.

What is stored. The PacketStream Fetch API does not store the URL, your User-Agent, or the page. DeepSeek’s privacy policy says it collects, processes, and stores personal data in the People’s Republic of China, and its Open Platform terms are governed by the law of mainland China.

For US government and defense work. As of October 2026, a Department of Homeland Security order requires federal civilian agencies to remove DeepSeek products, including third-party products and services developed using DeepSeek implementations, and section 1532 of the FY2026 National Defense Authorization Act bars Defense Department contractors from using DeepSeek-developed artificial intelligence on their Defense Department contracts. If you sell to these buyers, these rules may reach the tools in your stack.

Why choose PacketStream

• You read sites that block datacenter traffic. Each PacketStream fetch goes out through a residential IP, and a 403, 429, or 503 is tried again, up to twice, from a different IP address.
• You need a page as visitors in one country see it. Set country on the API to choose the exit country.
• Your agent reads long documents. Request up to 500,000 characters at a time, then continue from start_index.
• You need to know what you fetched. Every response gives the final URL after redirects and the HTTP status, so your code can record and check them.
• You don’t want the pages you read kept. PacketStream records each fetch’s ID, outcome, latency, and charge, and does not store the URL, your User-Agent, or the page.

Frequently asked questions

What does the DeepSeek Fetch API accept?

On October 29, 2026, its API reference listed one request field, the URL, and a response with the page title and its content as Markdown. PacketStream’s Fetch API also accepts country, user_agent, content, include_links, max_length, and start_index, and returns the final URL, HTTP status, title, and description with the content.

Does PacketStream fetch pages from residential IPs?

Yes. Every fetch goes out live through PacketStream’s residential network, from the United States unless you choose another country. When a site answers 403, 429, or 503, fetch asks again up to twice, each time from a different IP address, within the 25-second limit.

Where does DeepSeek store my data?

DeepSeek’s Open Platform terms apply its privacy policy to the personal information you provide. That policy, last updated February 10, 2026, says DeepSeek collects, processes, and stores personal data in the People’s Republic of China. It counts your inputs as personal data and keeps account, input, and payment data for as long as you have an account. PacketStream’s Fetch API records each request’s ID, outcome, latency, and charge, and does not store the URL, your User-Agent, or the page.

Do US government rules restrict DeepSeek?

As of October 2026, yes, for some buyers. A Department of Homeland Security order, published in the Federal Register on October 20, 2026, excludes DeepSeek products from federal civilian agency procurements and requires those agencies to remove DeepSeek products from their IT systems, including third-party products and services developed using DeepSeek implementations. Separately, section 1532 of the National Defense Authorization Act for Fiscal Year 2026 (Public Law 119-60) has, since January 17, 2026, barred Department of Defense contractors from using artificial intelligence developed by DeepSeek in performing a Defense Department contract, unless the Secretary of Defense grants a waiver.

Can my AI agent use PacketStream Fetch through MCP?

Yes. The PacketStream MCP server’s packetstream_fetch tool reads a page with the same URL rules, limits, and errors as the API, and packetstream_search runs a live Google search. It works in any MCP client that can send a custom Authorization header, and Claude custom connectors can sign in with your PacketStream account instead of a key.
