Frequently Asked Questions

Fill out the application form above with your company details and a description of how you plan to use our API. Our team reviews applications within 1-2 business days. Once approved, you will receive your API key via email.

Rate limits are configurable per API key. The standard tier allows 60 requests per minute, with professional (120/min), business (300/min), and enterprise (600/min) tiers available. If you need higher limits, contact us after your application is approved.

All API endpoints accept and return JSON (application/json). Dates follow ISO 8601 format (YYYY-MM-DD). Currency amounts are returned as string values with two decimal places to avoid floating-point issues.

Yes. Upon approval, you will receive both a sandbox API key and a production API key. The sandbox environment returns realistic mock data and does not create real bookings, making it safe for development and testing.
