Hey hunters! I'm building Domain Intelligence API.
I kept running dig + whois + mxtoolbox separately to answer: Does this domain have MX? SPF? DNSSEC? Who owns it?
So I combined it into one call:
curl "https://domain-api-bpps.onrender..."
Live demo needs no signup, docs are OpenAPI, Postman in repo. Free to try, paid via RapidAPI for volume.
What would make you switch? Batch check next? SSL info?
