Authentication

All API requests require authentication using an API key passed in the Authorization header.

Getting Your API Key

Sign up at hiapi.ai
Go to Dashboard → API Keys
Click Create New Key
Copy the key — it won’t be shown again

Using Your API Key

Include the key in the Authorization header with the Bearer prefix:

curl -X POST https://api.hiapi.ai/v1/images/generations \
  -H "Authorization: Bearer sk-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"model": "dall-e-3", "prompt": "hello world"}'

from openai import OpenAI

client = OpenAI(
    api_key="sk-your-api-key",
    base_url="https://api.hiapi.ai/v1"
)

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-your-api-key",
  baseURL: "https://api.hiapi.ai/v1"
});

Security Best Practices

Never expose your API key in client-side code or public repositories
Use environment variables to store your key: HIAPI_API_KEY
Rotate keys regularly from the Dashboard
Use separate keys for development and production
