Overview

Authentication

All API requests require authentication using API keys or OAuth tokens.

API Key Authentication

Include your API key in the request header:

curl -H "Authorization: Bearer YOUR_API_KEY" \
     https://api.example.com/v1/endpoint

OAuth Authentication

For OAuth authentication, follow the OAuth 2.0 flow:

1. Redirect users to the authorization endpoint
2. Handle the callback with the authorization code
3. Exchange the code for an access token
4. Use the access token in API requests

Base URL

All API requests should be made to:

https://api.example.com/v1

Rate Limits

• Free Tier: 100 requests per hour

Rate limit headers are included in all responses:
