Our verdict on Domainee Domain Availability Checker API

Domainee Domain Availability Checker API is a REST API for developers who need to check a domain across one or more top-level domains. It returns per-TLD availability results and uses DNS and RDAP fallback checks. The API requires no key or signup, supports browser requests through CORS, and also has a visual checker for users who prefer a web interface. It is best suited to lightweight availability checks embedded in browser-based or API-driven workflows.

Its clearest strength is the focused response model. Results use a JSON envelope for success and errors, while the service reports caveats such as registrar locks and premium domains. That gives developers more context than a simple available-or-unavailable result. The platform fit is also direct: API access is the core offering, and CORS support allows browser requests without adding an authentication step. Rate limits are documented at 30 requests per minute and 500 requests per day per IP address.

The checker is described as free and unauthenticated, making it practical for small projects and initial integrations. Domainee’s broader plans include Free with API access, webhooks, dashboards, CORS, and no API key requirement, while Scale is listed at $0.20 per domain per month with 100 GB of monthly bandwidth and automatic volume discounts from 1,000 domains. The checker itself remains narrow in scope: it focuses on checking domains rather than generating names or processing bulk searches. Choose it for straightforward browser API checks; consider another tool if domain generation or high-volume workflows are central requirements.
