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, returned as one ES256-signed attestation. Flat $0.15 per batch: 40% below the per-domain price of single calls at a full batch.

Verify a business or domain is real and established before your agent pays an invoice, onboards a vendor, or trusts it. A business-verification oracle for KYB, vendor screening, and fraud checks: RDAP registration age, DNS (A/MX/NS), email posture (SPF/DMARC), and HTTPS reachability. Returns a signed attestation with a 0-100 trust score and evidence URLs. Checking several domains? /verify/business/batch verifies up to 5 in one signed call at a flat $0.15, cheaper from four domains up.

Fact-check a single factual claim against web evidence before your agent relies on it. A fact-checking oracle and hallucination guard: returns a verdict (supported / contradicted / insufficient), a confidence score, and citations, as a signed attestation.

Check that a URL is live and its data is fresh before your agent acts on its contents. A freshness oracle: returns HTTP status, Last-Modified/ETag, a content SHA-256, and whether the content changed versus a prior hash. Returns a signed attestation.
