DeepSeek - PromptGuard

Proxy

Proxy Base URL: https://api.promptguard.co/api/v1Point your LLM SDK’s base_url / baseURL to this endpoint. Your existing provider API key goes in the Authorization header as usual; add your PromptGuard key via X-API-Key.

Model ids starting deepseek- go to DeepSeek, such as deepseek-chat and deepseek-reasoner. Hugging Face’s deepseek-ai/ ids are the exception: they go to Hugging Face. DeepSeek speaks OpenAI’s wire format, so PromptGuard forwards your request to api.deepseek.com/v1 as you sent it and returns DeepSeek’s reply unchanged. Any OpenAI client works.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.promptguard.co/api/v1",
    api_key=os.environ["DEEPSEEK_API_KEY"],  # forwarded to DeepSeek
    default_headers={"X-API-Key": os.environ["PROMPTGUARD_API_KEY"]},
)

response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.promptguard.co/api/v1',
  apiKey: process.env.DEEPSEEK_API_KEY, // forwarded to DeepSeek
  defaultHeaders: { 'X-API-Key': process.env.PROMPTGUARD_API_KEY },
});

const response = await client.chat.completions.create({
  model: 'deepseek-chat',
  messages: [{ role: 'user', content: 'Hello!' }],
});
console.log(response.choices[0].message.content);

curl https://api.promptguard.co/api/v1/chat/completions \
  -H "X-API-Key: $PROMPTGUARD_API_KEY" \
  -H "Authorization: Bearer $DEEPSEEK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "deepseek-chat", "messages": [{"role": "user", "content": "Hello!"}]}'

DeepSeek keys cannot be stored as provider keys yet, so send yours in Authorization on every request.

Auto-instrumentation

DeepSeek has no SDK of its own; DeepSeek’s docs use the OpenAI client. Pointed at api.deepseek.com, that client is the openai package, which auto-instrumentation patches, so init() scans those calls too.
