New since the last launch: three free checkers. DMARC, SPF and MX. No signup, no card.
Paste a domain and the record is parsed, not dumped: the DMARC policy and where reports go, the SPF all-qualifier and how many of the 10 permitted lookups you have spent, and which provider really runs the mail.
Same DNS code that scores email and domains inside the API. A missing record says so; a DNS failure says that instead, because those are different answers.
Most fraud tools answer one question at a time: is this IP a VPN, is this email disposable, is this phone real. LayerCall returns IP, email, phone, domain and device together, plus the relationships between them, which is where fake signups actually show up.
Every response carries a 0-100 score, an allow/review/block verdict, and the individual signals behind it, so a decision can be explained rather than only made.
It also verifies AI agents by signature. Free tier, no card.
