deeptunnel

DeepSeek → Anthropic API proxy.
Run DeepSeek behind the Anthropic SDK, Claude Code, or any tool that speaks the Anthropic Messages API.

Install

pip install deeptunnel

The WASM proof-of-work solver (sha3_wasm_bg.wasm, ~26 KB) is downloaded automatically from GitHub on the first run and cached in ~/.cache/deeptunnel/. You can also place the file next to the script manually to skip the download.

Quick start

# 1. Set your DeepSeek bearer token
#    Get it: browser DevTools → Network → any DeepSeek request → Authorization header
export DEEPSEEK_TOKEN="your-token-here"

# 2. Start the proxy
deeptunnel

# 3. In another shell, point the Anthropic SDK at it
export ANTHROPIC_BASE_URL="http://localhost:8765"
export ANTHROPIC_API_KEY="local-proxy-key"
claude          # or any other Anthropic SDK client

Flags

deeptunnel --model expert --no-search --think --port 9000

Environment variables

Multiple tokens (auto-rotation)

export DEEPSEEK_TOKEN="token1,token2,token3"
deeptunnel

Tokens rotate automatically when DeepSeek returns a "server busy" / generation_timeout response.

How it works

1. Receives Anthropic-format /v1/messages requests.
2. Translates Anthropic tool definitions → XML schema in the prompt.
3. Solves DeepSeek's proof-of-work challenge (via WASM).
4. Forwards the request to chat.deepseek.com.
5. Parses DeepSeek's plain-text response for <tool_use> blocks.
6. Re-emits proper Anthropic tool_use / text content blocks as SSE.

Manual WASM placement

If the automatic download fails (firewall, air-gapped environment), download the file manually and place it in ~/.cache/deeptunnel/:

mkdir -p ~/.cache/deeptunnel
curl -L 'https://github.com/IMApurbo/deepseek_scrapper/blob/main/deepseek-cli/sha3_wasm_bg.wasm' \
     -o ~/.cache/deeptunnel/sha3_wasm_bg.wasm
