## Spaw

Verification API that bills per answered lookup across six signals on one key and one balance: Email verification, Phone intelligence, IP intelligence, Address verification, Business verification against open registers, and Cross-signal consistency, which runs any subset of the first four in one call and names where they agree and where they do not. The phone side reads the numbering plan and the regulators' own allocation tables to name the line type, the block holder and the blocks nobody holds, and flags the numbers that are not a person's handset.

## ClearoutPhone

ClearoutPhone is a phone validation service from Clearout sold as credits that never expire, with a 1-credit Standard mode and a Smart mode that runs a real-time telecom query, at up to 5 credits, where static data is uncertain.
