Why this exists

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.

History cannot be backfilled

The exchange-rate archive grows every business day and each point keeps its source URL and content hash. A competitor can read today’s bulletin too — nobody can produce last quarter’s.

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.

Validation1

/v1/phone/validate Phone Number Validation deterministic 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.

Credits are consumed per call and cache hits are free. Requests without a key run on a narrow per-IP demo quota so you can evaluate before signing up.

The API key is e-mailed the moment payment clears. Upgrades keep the same key, so your integration is never broken.

Every endpoint is also published over the Model Context Protocol, so Claude, ChatGPT or your own agent can call it directly — no glue code, no wrapper functions. The assistant sees the same input schemas and the same metering.

Currently 13 tools. New endpoints appear automatically; nothing to update on your side.
