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.

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.

/v1/tr/pay/qr Turkish FAST / TR Karekod Payload deterministic 1 credit

Builds a person-to-person TR Karekod (FAST) payment payload from IBAN, name and optional TRY amount. Text only — no PNG.

Turkish instant payments (FAST) can start from a TR Karekod that encodes the payee IBAN and name in EMV-style TLV. This builds the person-to-person organisation (payload format indicator 750210): application template with IBAN, payee name, optional 12-digit kuruş amount, optional free-text explanation, and a CRC-16/CCITT-FALSE trailer. The Turkish IBAN is normalised and checked with ISO 7064 mod-97; non-TR IBANs and non-TRY currencies are rejected. This does not send money and does not render a QR image.

Parameters

iban*	string	Beneficiary Turkish IBAN (with or without spaces).
name*	string	Payee name shown to the payer (2–26 chars after trim).
amount	number	TRY amount; omitted → static QR (payer enters amount).
explanation	string	Optional remittance note (application free field 10).
currency	string	Must be TRY if provided.
generatorCode	string	QR generator / EFT code (4 digits). Defaults to last 4 of the IBAN bank code.

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