Orisift

Not yet independently verified. The launch date rests on the maker's own Show HN post of 12 October 2026. Capabilities, credit costs and prices come from the maker's own pages. No independent report was found. Other products share the name Orisift only by coincidence of spelling; this listing is the validation API at orisift.com. We will update this when it can be confirmed, and remove this note.

Orisift is a validation API from Tervra Limited, a company registered in England and Wales with its office in London. A developer sends one phone number, email address, IP address or domain to a single endpoint and gets back a verdict, a risk score and a list of signals, each naming its source. The maker presented it on Hacker News on 12 October 2026.

What it does

Phone checks parse and normalise a number and test it against national numbering plans, including reserved and fictional ranges. Email checks cover syntax, domain existence, mail routing, role addresses and a list of 8,985 known throwaway providers. IP checks classify the address, screen special-purpose ranges and read reverse DNS. Domain checks look at delegation, address records, mail routing, SPF and DMARC. The site is plain about limits: it does not confirm that a mailbox exists, that a phone line is live or who operates it, and it is not a threat feed. A response can carry a recommended action under a named policy, and retries with an idempotency key are not charged twice.

Who it is for

The product suits developers and small teams who want to screen signups and clean contact data without running their own resolvers or maintaining numbering-plan data. Its terms bar use for eligibility decisions on credit, insurance, employment or housing.
