DeepSeek V4 Pro API

DeepSeek V4 Pro API Endpoint and Parameters

Send requests to POST /chat/completions at https://api.openoctopus.com/v1. The call uses your OpenOctopus API key as a bearer token and accepts the standard chat completion parameters.

For multi-turn coding or agent tasks, keep temperature low and validate tool calls before executing them.

Quick Start With DeepSeek V4 Pro API

Use your OpenOctopus key as a bearer token and point any OpenAI-compatible client at the OpenOctopus base URL.

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_OPENOCTOPUS_API_KEY",
    base_url="https://api.openoctopus.com/v1"
)

response = client.chat.completions.create(
    model="deepseek-v4-pro",
    messages=[{"role": "user", "content": "Review this code for risky edge cases."}],
    temperature=0.2
)

print(response.choices[0].message.content)

curl https://api.openoctopus.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENOCTOPUS_API_KEY" \
  -d '{
    "model": "deepseek-v4-pro",
    "messages": [{"role": "user", "content": "Review this code for risky edge cases."}],
    "temperature": 0.2
  }'

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.OPENOCTOPUS_API_KEY,
  baseURL: "https://api.openoctopus.com/v1"
});

const response = await client.chat.completions.create({
  model: "deepseek-v4-pro",
  messages: [{ role: "user", content: "Review this code for risky edge cases." }],
  temperature: 0.2
});

console.log(response.choices[0].message.content);

Test prompts in the playground first. Move to the DeepSeek V4 Pro API when output format, context size, and validation rules are stable.

DeepSeek V4 Pro API Pricing

Billing follows per-token usage: input tokens, output tokens, and any reasoning tokens consumed during generation. Long-context requests and agent loops can increase output size quickly, so set output caps and log usage per workspace.
