Free-Deepseek-API

Self-hosted OpenAI-compatible API proxy for chat.deepseek.com. Runs a real browser session via CloakBrowser (stealth Chromium), so the site sees a genuine browser fingerprint and the WAF / PoW checks pass on their own — no captcha services, no manual solving.

Built for use with opencode and any other OpenAI-compatible client.

Install

git clone https://github.com/lothiann/Free-Deepseek-API.git
cd Free-Deepseek-API
pip install -r requirements.txt

CloakBrowser ships its own Chromium, so there is no separate playwright install step.

Get the token

chat.deepseek.com keeps the session in localStorage, not a cookie. Open https://chat.deepseek.com → DevTools (F12) → Console:

copy(JSON.stringify({
  token:    JSON.parse(localStorage.userToken).value,
  user_id:  JSON.parse(localStorage['__appKit_userInfo'] || '{}').value?.id || '',
  web_id:   JSON.parse(localStorage['__tea_cache_tokens_20006317'] || '{}').web_id || '',
  device_id: localStorage['deepseek-device-id:chat'] || ''
}, null, 2))

Paste into accounts.json:

{
  "rotate_every": 10,
  "accounts": [
    {
      "name": "main",
      "token": "64-char opaque userToken",
      "email": "optional - your login",
      "password": "optional - your password"
    }
  ]
}

Field	Description
token	userToken from localStorage (required)
user_id, web_id, device_id	optional; filled in automatically if omitted
email, password	optional; enable automatic token refresh
rotate_every	requests per account before switching to the next one

accounts.json holds secrets (email/password if set) — keep it out of git; the repo ships with an empty template. Accounts rotate round-robin.

Models

id	Behaviour
deepseek-chat	site's Instant mode, DeepThink off
deepseek-reasoner	DeepThink on — reasoning streamed via delta.reasoning_content

Run

python main.py

Interactive menu: 1 start, 2 toggle auto-refresh tokens, 3 toggle account rotation, 4 change API port, 5 open accounts.json, 6 toggle window hiding, 7 GitHub, 8 exit.

Server starts on http://127.0.0.1:8493/v1.

Test

curl http://127.0.0.1:8493/v1/models

curl -N http://127.0.0.1:8493/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d "{\"model\":\"deepseek-reasoner\",\"stream\":true,\"messages\":[{\"role\":\"user\",\"content\":\"say OK\"}]}"

# account status
curl http://127.0.0.1:8493/accounts

opencode

Add to ~/.config/opencode/opencode.jsonc (or opencode.json):

{
  "provider": {
    "deepseek": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "DeepSeek (web proxy)",
      "options": {
        "baseURL": "http://127.0.0.1:8493/v1",
        "apiKey": "sk-nothing"
      },
      "models": {
        "deepseek-chat":     { "name": "DeepSeek Chat",     "limit": { "context": 2621440, "output": 2621440 } },
        "deepseek-reasoner": { "name": "DeepSeek Reasoner", "limit": { "context": 2621440, "output": 2621440 } }
      }
    }
  }
}

apiKey is ignored — the proxy binds to 127.0.0.1 and does not check it.

Endpoints

Endpoint	Description
GET /v1/models	model list
POST /v1/chat/completions	chat, streaming & non-streaming, with tools and images
GET /accounts	rotation status
GET /debug/last	last upstream response, for troubleshooting

Notes

• Tool calling works out of the box: send standard OpenAI tools, results come back as role: "tool" messages — nothing to configure.
• image_url parts (data URL or remote http) are supported.
• usage counts characters, matching the site's own input limit (2621440) — the limit values above account for that.
• Stale tokens: DeepSeek rotates userToken server-side and has no refresh endpoint. With email/password set, the proxy re-logs in and updates accounts.json automatically (menu option 2).
• An account can be suspended by DeepSeek for "violation of user policies" — no proxy setting prevents that; rotation to another account is the only mitigation.
• Logs are written to logs/, the last raw response to last_response.json.
