# Lookproof BIMI Record Checker

> Lookproof BIMI Record Checker is a paid API for AI agents from api.lookproof.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Validates a domain's BIMI record syntax, logo URL, certificate URL, and DMARC enforcement status to diagnose why brand logos don't appear in email clients

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lookproof-bimi-record-checker-4c4cccd5
```

Example prompt: Why isn't our brand logo showing up in Gmail for emails sent from stripe.com — can you check the BIMI record and tell me if the syntax is correct, whether DMARC is enforced at quarantine or reject, and what logo and certificate URLs are configured?

## When to prefer this

Use this endpoint specifically when diagnosing why a brand logo (BIMI/VMC) is not displaying in email clients, or when auditing BIMI configuration for a domain. It's the right choice when you need to inspect BIMI record syntax, verify DMARC enforcement level, or check logo/certificate URL validity without needing to download the actual assets. Prefer the sibling full mail-security report endpoint when you need a broader view of SPF, DKIM, and MTA-STS alongside BIMI.

## Known failure modes

- Domain has no BIMI record — returns not-found or empty result
- BIMI record syntax is malformed — returns parse error details
- DMARC policy is not enforced (none or pct<100) — flagged as non-compliant
- Domain does not exist or DNS lookup fails — DNS resolution error
- Selector specified does not exist — falls back to default or returns not-found
- Logo or certificate URLs are HTTP instead of HTTPS — flagged as invalid

## How this service works

Check SPF, DMARC, DKIM, MTA-STS, DNSSEC and more, with results that explain what was found and why. Free browser checks and a pay-per-request API with x402.

## Output

Returns the parsed BIMI record for the domain including: the selector used (custom or default), the full v=BIMI1 record syntax, the HTTPS logo URL, the HTTPS VMC/certificate URL, the SVG logo path, and whether DMARC is enforced at quarantine or reject with pct=100. The logo and certificate files themselves are not downloaded or validated.
