Frequently Asked Questions
What authentication does the API use?
Bearer token authentication. Pass your API key in the Authorization header: 'Authorization: Bearer ext_YOUR_KEY'.
What's the rate limit?
API requests are limited by your plan's monthly page allowance. Each successful extraction uses one page credit.
Is there an SDK?
Not yet, but the API uses standard HTTP and JSON, so any HTTP client works. We provide curl examples in the docs.
