What does Orisift do?
Orisift is a REST API for screening the details people type into signup forms.
POST /v1/lookup checks one phone number, email address, IP address or domain. POST /v1/signup checks all four in one request and returns a separate result for each, so you can decide field by field what to accept, what to ask again and what to hold for review.
Checks include E.164 formatting, reserved and fictional phone ranges, email domain mail setup, known throwaway domains and role addresses such as admin@ or info@. Each result lists the sources it used and what it could not establish.
There is a Node SDK (@orisift/sdk) with a Supabase Auth helper, docs at orisift.com/docs and an OpenAPI file. A free checker on the homepage gives 3 previews a day with no account. Freemium: 500 free credits once, no card.
