Expose parallel domain checks and social handle queries directly to your applications, custom GPT Actions, and AI search workflows using Namecheckly's new public JSON API.

We are thrilled to announce the launch of Namecheckly's public JSON API. AI assistants, search bots, and developers can now query real-time domain and social media handle availability directly from their applications via a free, CORS-enabled endpoint: GET /api/check. Start building at our Developer API Portal or inspect the OpenAPI 3.0 Schema.

Announcing Namecheckly API: Real-Time Naming API for AI Search

We are excited to launch Namecheckly's public JSON search API! When building a new app, SaaS, or blog, naming is the first major hurdle. In the era of AI-driven search (ChatGPT, Claude, Gemini, Perplexity), founders are brainstorming names inside chat consoles.

AI models are excellent at generating creative name variations, but they have a fatal flaw: they don't know what names are actually available to register.

With our new real-time availability API and OpenAPI specification, we are bridging this gap. AI agents and custom developer integrations can now check name availability across domains and social networks simultaneously in under 2 seconds.

Frequently Asked Questions

Is the Namecheckly API free to use?

Yes. The API is completely free and requires no signup or API keys. It supports CORS so you can query availability directly from client-side code without running into cross-origin blockages.

How can I integrate the API into my custom ChatGPT Action?

Copy the link to our OpenAPI schema (`https://namecheckly.com/openapi.yaml`) and paste it into the Actions settings of your Custom GPT. This allows ChatGPT to query domain and social handle statuses automatically during name brainstorming.

Does the API response include registrar links?

Yes. For every available domain, the JSON response returns a pre-formatted Namecheap registration path. This allows AI agents to route users directly to register their chosen names seamlessly.
