Bulk company verification
Bulk company verification: verify up to 5 business domains in one signed attestation. Screen a prospect or lead list, qualify target companies before outreach, check vendor and supplier lists, or clear invoice batches. Same checks as /verify/business per domain (RDAP registration age, DNS, SPF/DMARC, HTTPS) with a 0-100 trust score each, as one ES256-signed attestation. Flat $0.15 per batch: 40% below the per-domain price of single calls at a full batch.
