// why truval
01
agent-native
OpenAPI 3.1 spec at /openapi.json. Your agent reads it and writes your integration. No docs page to navigate, no SDK to learn.
02
five layers, early exits
Syntax → disposable → MX → SMTP → signals. Bad addresses fail in under 5ms. Real addresses get a confidence score, not just true/false.
03
honest about limits
Gmail blocks SMTP probing from every third party. We tell you that with smtp_blocked: true and a calibrated 0.75 confidence — not a fake "valid".
04
EU-hosted · GDPR
Data stored in Europe. Delivered worldwide.
05
typo detection
gnail.com → suggestion: "gmail.com". Agents surface this before a bounce happens. Edit distance against the 20 most common providers.
06
usage-based pricing
Free tier, then pay per call. No seats, no plans. Your agent runs more tasks, you pay a bit more. Code doesn't churn.
