I built DeepWrap: a Python SDK and CLI for DeepSeek Chat

A developer built DeepWrap, a Python SDK, CLI, and local HTTP API wrapper for DeepSeek Chat, to make the browser-only service accessible from code and terminal workflows. The project required solving challenges like WebAssembly-based proof-of-work challenges and implementing browser-based authentication, along with parsing complex chat streams. DeepWrap is available via pip install and supports interactive terminal sessions, one-shot commands, and an experimental "God Mode" feature.

DeepSeek Chat was free in the browser. But the moment I wanted to use it like a developer, it became a different story. That annoyed me more than it probably should have. If something is usable in the browser, why should it suddenly feel blocked, awkward, or artificially expensive the moment you want to call it from Python, from your terminal, or from your own local tools? That mismatch was the whole reason I built DeepWrap . What started as “let me inspect a few requests and see how hard this is” turned into a full project: a Python SDK , a terminal CLI , and a local HTTP API wrapper for DeepSeek Chat. The real motivation was simple: DeepSeek was free in the browser, but not free in the way developers actually want to use it. And that felt absurd. I wanted to use it in real workflows: I did not want to babysit browser tabs forever just to use a model in a developer-friendly way. So the idea behind DeepWrap was basically: take the browser experience and make it usable from code. At first, I genuinely thought this was going to be easy. I opened DevTools, went to the Network tab, started looking at the XHR requests, and my first thought was: “Okay, this is probably just a matter of replaying the right requests with the right headers.” That optimism did not survive very long. The first step was just observing the flow: At a glance, the flow looked simple: That was enough to sketch the basic client structure. Then came the first real problem: proof-of-work . Some requests were not just normal authenticated calls. The browser had to solve a PoW challenge, and that logic was implemented with WASM . So the project instantly got more interesting. Instead of only replaying requests, I had to: That was the point where this stopped being a “quick wrapper.” I also didn’t want the whole thing to rely only on pasting bearer tokens manually. Yes, that works. No, that doesn’t feel great. So I added browser-based auth too. That meant building a flow that could: That part was messy, but necessary if I wanted the project to feel real. Once auth and PoW worked, I still had to handle the actual chat stream. And it was not just “text in, text out.” The stream included: So I built a parser that could: parent message id That let the public API stay simple even if the internals were not. Once the Python API felt stable, I pushed it further: So DeepWrap gradually became three things: That was the point where it stopped feeling like a hack and started feeling like a product. If you just want to try it, the flow is simple. pip install deepwrap python from deepwrap import Client client = Client If you already have a token configured, that’s enough. chat = client.chats.create session model="expert" response = chat.respond "Explain quantum computing in one short sentence.", thinking=True, search=True, stream=False, print response for chunk in chat.respond "Write a short explanation of black holes.", thinking=True, search=True, stream=True, : print chunk, end="", flush=True print print chat.respond "My name is Nika.", stream=False print chat.respond "What is my name?", stream=False That works because the session keeps track of the conversation state internally. I also wanted it to feel good in the terminal. You can start the interactive interface with: deepwrap Or use one-shot terminal calls: deepwrap chat "Explain recursion in one sentence." That was important to me because sometimes you don’t want a script — you just want a fast terminal workflow. I also added an experimental feature called God Mode . This is not some magical hidden model. It is a session-level behavior override implemented through prompt injection on the first user turn . In practice, that means: I added it mostly as a developer/testing feature, not as a normal mode for everyday use. So I treat it as exactly what it is: an experimental override for controlled testing , not something meant for general use. A few important notes: DeepWrap is an unofficial wrapper, so use it responsibly. The project is open source here: GitHub: https://github.com/Kuduxaaa/deepwrap This whole project started from a very simple frustration: “Why is it free in the browser, but awkward the moment I want to use it like a developer?” Then it turned into a much bigger project than I expected: reverse-engineering requests, dealing with PoW WASM, browser auth, session handling, streaming, CLI UX, and local API design. If you check it out, I’d genuinely love feedback on: If something feels awkward, overbuilt, underbuilt, or just weird, tell me. That kind of feedback is the most useful.
