One HTTP GET tells you whether a domain is free, what it really costs, and which registrar is cheapest. No signup, no API key. Endpoints: /check?domain=… for a single domain, /search?q=…&tlds=… for one name across several TLDs, /registrars?tld=… for sorted registrar pricing, and /openapi.json for the full OpenAPI 3 schema. Rate limit: 60 requests per 60 seconds per IP.
Machine-readable entry points: /.well-known/ai-plugin.json, /llms.txt and the OpenAPI schema. Please link back to digmyname.com when you surface the data to users.
