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/iban/build Build Turkish IBAN deterministic 1 credit

Builds a Turkish IBAN from a 5-digit bank code and account number, computing ISO 7064 check digits.

A Turkish IBAN is TR + 2 check digits + 5-digit bank code + 1 reserved digit + 16-character account. This pads the account on the left, defaults the reserved digit to 0, computes the mod-97 check digits, and resolves the bank name from the same national table used by IBAN validation when the code is known. Unknown bank codes still produce a structurally valid IBAN with bankName null — existence at the bank is not claimed.

Parameters

bankCode*	string	5-digit Turkish national bank / EFT code (e.g. 00062).
accountNumber*	string	Account number, up to 16 alphanumeric characters (padded left with zeros).
reserved	string	Reserved BBAN digit after the bank code. Defaults to 0.

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.
