The Draft insurer correspondence operation is part of the Insurance Claims Assist API on BRAINIAC.software. Prepare a human-reviewed FNOL, follow-up, or complaint letter. BRAINIAC.software does not send the message or make legal conclusions. It is exposed as POST /api/v1/claims/letter-draft and priced at $0.02 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: Policy documents and incident facts supplied by the caller. Limitations: Results are preliminary assistance, not legal advice or confirmation of coverage. Correspondence is a draft and is never 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.
