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.

/v1/tr/fuel/prices Turkey Fuel Prices 2 credits

Petrol, diesel and heating-oil pump prices for all 81 Turkish provinces, including the price in force on any past date.

Today's pump price is on a public web page; the archive is not. This endpoint answers the question that actually costs money: what was diesel in Ankara on 12 March? Pass `asOf` for the price in force on that day — if the distributor did not change prices that day, the previous price is carried forward and `effectiveFrom` says when it started, with `carriedForward: true`. Pass `from`/`to` to get the change events in a window, each with the percentage move. Every figure carries the source URL and a content hash of the page it was read from, so the number can still be defended in an audit years later. Leave `province` empty to list coverage.

Parameters

province string | number Province name or plate code — "Ankara", "istanbul" or 34. Leave empty to list covered provinces.
product "benzin" | "motorin" | "motorin_ekstra" | "gazyagi" | "kalorifer" | "fueloil" | "fueloil_yk" Fuel product. Omitted → every product available for that province.
asOf string Price in force on this date (YYYY-MM-DD). Omitted → latest known price.
from string With `to`: return the price changes in this window.
to string
includeDistricts boolean Adds districts whose pump price differs from the province reference price. 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.

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.
