Built for hostile input
A Turkish address arrives as "Cd." or "Cad." or "Caddesi", with the flat number glued to the building number. Generic parsers drop half of it silently. This one tells you what it could not place.
Every number carries its provenance
Each archived point stores the source URL and a content hash of the page it came from, and the archive is committed to a Merkle root anchored in Bitcoin. Every commitment — with its cutoff, leaf count and anchors — is published at /proof, so you can check for yourself how current the latest one is. The bulletins themselves are public and anyone can read them; what this adds is that a number you quote can be shown to be the number we held on that date, and that it has not been edited since.
You only pay for work
Repeated inputs come from cache and cost zero credits. If a response ever fails its own schema, the call is refunded automatically.

Phone Number Validation

1 credit
Validates and normalises a phone number to E.164, classifies the line type, and resolves the province for Turkish landlines.
For signup and checkout flows that need to store one canonical form and reject typos early. Turkish numbers are handled in depth: landline area codes resolve to a province, mobile and special ranges (toll-free 0800, fixed-rate 0850, premium 0900) are classified, and every accepted input comes back in both E.164 and national notation. One thing this endpoint deliberately does not claim: the current mobile operator. Turkey has had number portability since 2008, so a 0532 number may well be on another network today. Competing APIs report the prefix owner as "the operator" and customers pick SMS routes on that basis. We return it as `originallyAllocatedTo` with the caveat attached, because a confident wrong answer costs more than an honest gap.
Parameters
| phone* | string | Phone number in any common format. |
| defaultCountry | string | ISO 3166-1 alpha-2 country to assume when the number has no international prefix. Defaults to TR. |
