Introduction

Dropfakes helps you block fake signups, disposable inboxes, and low-quality leads before they enter your product, CRM, or sales pipeline. The API now covers direct email validation, agent-first workflows, reputation scoring, and DNS or domain utility tools.

What the API is for

The API is built for teams that need fast, machine-readable email risk signals inside product onboarding, signup flows, lead capture forms, and internal operations tooling.

What you can do here

Run lightweight disposable-email checks for fast gating.
Run detailed email checks that include DNS, SMTP, and reputation signals.
Score a domain before you trust the sender behind it.
Validate email lists in bulk.
Use agent-first validation endpoints with token-optimized response formats for LLM workflows.
Generate or inspect DNS records with public tools for DMARC, SPF, DNS, SSL, and WHOIS.
Use agent-first tools when an LLM needs DNS, SSL, or WHOIS context during automated investigations.
Inspect usage, logs, and analytics endpoints.
Access public utility endpoints such as plans and health.
