Mail, DNS and web checks for developers and AI agents
Lookproof provides read-only checks of email configuration, DNS records, and web settings through a browser interface and pay-per-request API.
Overview
Lookproof is a service for developers and AI agents that performs read-only checks of public DNS and mail configuration settings. It provides browser-based checks at no charge and a pay-per-request API that accepts x402 payments in USDC on Base.
The service audits email configuration including SPF, DMARC, DKIM, MX records and related security standards. It inspects domains and DNS records, showing selected record types with TTL and resolver information. Tools are also available for checking TLS certificates, security headers, HTTPS redirects and domain expiry.

Frequently looked up
- Q1What does Lookproof check?
- Lookproof checks publicly visible email configuration settings including SPF, DMARC, DKIM, MX records and DNS configuration. Each check reads public DNS and explains what it found in plain language.
- Q2What does Lookproof not do?
- Lookproof does not guarantee that mail is delivered or that a domain is secure. It does not read mailboxes or probe mail servers, and results describe only what is published at the time of the check.
- Q3How does payment work?
- Every API request is paid with x402 in USDC on Base. Prices are fixed and known before you pay. No account or subscription is required. Browser checks are free and rate limited.
- Q4Can I integrate Lookproof checks into AI agents?
- Yes. Lookproof publishes stable finding codes and will provide JSON schemas and machine-readable descriptions built from the same registry as the documentation pages, allowing integration into agents.
