Why this exists

Built for hostile input

A phone number arrives with spaces, a trunk zero and no country code; an IBAN arrives with one digit transposed. Generic validators answer yes or no and move on. These tell you what was wrong and what the input most likely meant.

Every rule carries its source

Checksums follow the published algorithms (IBAN mod-97, national BBAN structures, E.164 numbering plans). When an answer cannot be verified, the response says so instead of guessing — a structurally valid number is never presented as a registry match.

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.

/v1/tr/validate Turkish ID & Number Validation deterministic 1 credit

Validates Turkish national ID, tax number, IBAN, licence plate, IMEI, barcodes, KEP, MERSİS, postal code and ISBN from one endpoint, with type auto-detection.

Goes past a yes/no: resolves the bank behind an IBAN, the province behind a licence plate and the GS1 country prefix behind a barcode. Pure local computation — no upstream service is called, so latency is microseconds and the answer never changes for the same input.

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.

No monthly fee: sign in, add prepaid credits ($10, $25 or $50) and use the same key across every endpoint. You pay $0 when idle.

Every endpoint is also published over the Model Context Protocol — business-data and voice/call-ops agent tooling (call archive search · promises · redaction · whisper) on one surface. Claude, ChatGPT or your own agent can call them directly: same schemas, same metering, when quiet, no glue code.

Currently 43 tools. New endpoints appear automatically; nothing to update on your side.
