Detect duplicate companies API

Find duplicate companies by a normalized domain or company-name key, and flag fuzzy name matches with a confidence level. Different domains are not merged. Suggestions do not change a CRM.

The Detect duplicate companies operation is part of the CRM Data Intelligence API on BRAINIAC.software. Find duplicate companies by a normalized domain or company-name key, and flag fuzzy name matches with a confidence level. Different domains are not merged. Suggestions do not change a CRM. It is exposed as POST /api/v1/crm-intelligence/duplicate-company-detect and priced at $0.05 USDC on Base. Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: CRM contact and company records supplied as CSV or JSON. Limitations: No CRM system is contacted or changed. Contact details, company attributes, and relationships are not invented. Enrichment copies only caller-supplied facts into empty fields. A fuzzy match is a suggestion with a confidence level, not a completed merge. Records with different email addresses are not treated as the same person. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
