API Authentication

All API requests require a valid API key.

Header authentication

Include your key in the Authorization header:

Authorization: Bearer owlsk_your_api_key_here

Example request

curl -X POST https://api.owlstack.app/v1/publish \
  -H "Authorization: Bearer owlsk_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
    "body": "Hello from the API!",
    "platforms": ["twitter"]
  }'

API key format

OwlStack API keys are prefixed with owlsk_ followed by a random string:

owlsk_a1b2c3d4e5f6g7h8i9j0...

Key management

• Create keys at app.owlstack.app under Project Settings > API Keys
• Each key belongs to a project and inherits the project's plan
• Keys can be revoked immediately
• Create separate keys for production, staging, and development
