One flow, any list
A one-column CSV handles a single address or a larger list. The API validates the whole file, removes duplicates and schedules checks.
Email verification, ready to build with.
One API for your application, scripts and AI agents. Submit a CSV, follow progress and read the evidence behind each result.
Saved progress and results
Follow your verification by ID. Download finalized results as they become available, and return to the same saved job later.
Clear credit rules
Read your balance before submitting. Unknown outcomes are inconclusive and refund their held credit.
Built for agents too
Read every guide as Markdown, discover the documentation through llms.txt, or use the OpenAPI contract directly.
