How we check. Step 1 (client-side): POST /api/check with xcoux.com. The function hashes the SLD against our bloom filter (built daily from the .com zone). Step 2 (only if step 1 said "not in zone"): GET /api/rdap?domain=xcoux.com which HEADs VeriSign's RDAP endpoint to confirm whether the domain is held at the registry without active nameservers. Neither step logs your query. More on our data practices.
