Audit custom domain onboarding API

Compare a custom domain, tenant, ownership TXT records, DNS targets, and platform assignment status. A dangling name is a potential condition only when the supplied assignment is unassigned or deleted. The audit does not query DNS or claim the domain.

The Audit custom domain onboarding operation is part of the Domain Infrastructure Consistency Audit API on BRAINIAC.software. Compare a custom domain, tenant, ownership TXT records, DNS targets, and platform assignment status. A dangling name is a potential condition only when the supplied assignment is unassigned or deleted. The audit does not query DNS or claim the domain. It is exposed as POST /api/v1/domain-security/custom-domain-onboarding-audit 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: Caller-supplied DNS, certificate, and routing snapshots processed locally Caller-supplied custom-domain onboarding records processed locally Limitations: The records in the request are compared with each other. DNS, TLS, WHOIS, and BGP are not queried. Missing evidence is incomplete. It is not a confirmed inconsistency. An address or ASN change is not by itself malicious. A CDN or proxy address is expected only when the request supplies its host, range, ASN, or provider. A platform hostname is unassigned only when the request says so. A dangling DNS name is not proof of a takeover. infrastructure-health grades the supplied records, certificate names, expiry, and cipher names. A CNAME is dangling only when its target has no A or AAAA in the same snapshot. onboarding-readiness compares the supplied token, CNAME target, and certificate flag. A mismatched CNAME raises the hijacking index and is not proof of a takeover. Outputs are compliance prechecks, drafts, or data lookups for human review. They are not official determinations, legal advice, identity confirmation, or certified filings.
