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.
Developers who want the numbering plan and the regulators' own allocation tables read for them, with the dataset behind every field named in the answer and the number never leaving the server.
Telnyx Number Lookup
Telnyx Number Lookup is a per-query number API sold beside Telnyx's carrier services, priced separately for local routing number (portability and carrier), MCC/MNC, and CNAM caller name.
Teams that need to know who serves a number today, on numbers that have been ported, at the lowest published per-query price.
Twilio Lookup
Twilio Lookup is a phone number API sold as separately priced data packages on top of a Twilio account: validating and reformatting a number is free, and line type, caller identity, line status and risk each cost their own per-request fee.
Teams already sending messages through Twilio that want line type, caller identity and SMS-pumping risk billed on the same account as their traffic.
