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.

Time Series1

/v1/series/history Time Series History 2 credits

Returns the accumulated history of public data series with change statistics and a source receipt for every point.

Currently ingesting the Turkish Central Bank daily FX bulletin (`tcmb.usd`, `tcmb.eur`, …), normalised to one unit so JPY-style 100-unit quotes stop biting. Leave `seriesId` empty to list the catalogue. `fillGaps` carries the last value across weekends and holidays; `includeEvidence` attaches the source URL and content hash for every point, so a value can still be defended years later.

Parameters

seriesId string Seri kimliği, ör. `tcmb.usd`. Boş bırakılırsa katalog döner.
from string Başlangıç tarihi (dahil).
to string Bitiş tarihi (dahil).
limit integer default 365
fillGaps boolean default false
includeEvidence boolean Her nokta için kaynak URL ve içerik özetini döndürür. default false

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.

Use it from an AI assistantthe same catalogue, exposed as MCP tools

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