Extract and check a certificate of insurance API
Extract PDF/image fields with confidence, then compare them with contract requirements. Uncertain OCR is WARN and is never treated as verified.
The Extract and check a certificate of insurance operation is part of the Certificate of Insurance API on BRAINIAC.software. Extract PDF/image fields with confidence, then compare them with contract requirements. Uncertain OCR is WARN and is never treated as verified. It is exposed as POST /api/v1/coi/analyze and priced at $0.10 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: The certificate and contract requirements provided in each request. OCR/extraction confidence is included in results. Limitations: Uncertain extraction is flagged for human review and is never treated as verified. Results are not a coverage determination; draft emails are not sent automatically. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
