Biggest daily gainers and losers
API · /cbr-api
CBR Russia FX API
Live official exchange rates from the Central Bank of Russia (Bank of Russia) — the daily fixing the regulator publishes for the rouble (RUB) against 50+ currencies. Unlike euro- or dollar-based feeds, this is the rouble's own official reference board: every currency with the bank's nominal, the official RUB value, the previous-day value and the day-over-day change in absolute and percentage terms. Get the whole board with per-unit RUB values, one currency's official fixing in full, an official CBR cross rate between any two currencies via the rouble, or a ranking of the biggest daily gainers and losers against the rouble. Live, no key, nothing stored. Distinct from the ECB, SNB, Bank of Canada, Norges Bank, NBP, CNB and BCB feeds and from market mid-rates — this is the Central Bank of Russia's official rouble fixing with day-over-day deltas and official cross rates. Perfect for FX, treasury, accounting, remittance and analytics apps.

RUTUBE API
Live data from RUTUBE, the largest Russian video platform with tens of millions of users — served straight from its public web API, no key, nothing cached. Search videos by query and get their view counts, duration and channel; pull one video's full stats (views, duration, publish date, category and author); and list a channel's recent uploads by its person id. A distinct video-platform feed, separate from YouTube, Vimeo, Bilibili, Dailymotion, PeerTube and other video APIs.

National Bank of Belarus API
Live official exchange-rate data from the National Bank of the Republic of Belarus (NBRB), the central bank of Belarus, for the Belarusian rouble (BYN): the NBRB official rate for every published currency (normalised to one unit), a single currency's rouble-per-unit rate and inverse, the daily time series of a currency's official rate over a full date range, and currency conversion between any two published currencies (including BYN) cross-computed through the rouble at NBRB rates.

Currency Converter API
Live foreign-exchange conversion across 160+ world currencies — the plain, developer-friendly converter. Get the latest rates for any base currency, convert an amount between any two currencies, read the rate (and inverse) for a single pair, or list every supported currency. Rates are read live from an open exchange-rate source that aggregates a broad set of feeds and covers far more currencies than ECB-only data — including emerging-market and exotic currencies such as the Nigerian naira, Indian rupee or Vietnamese dong. This is the everyday convert / latest-rates utility a checkout, invoice, pricing page or travel app needs — distinct from the FX analytics APIs in the catalogue (historical date ranges, pip and position-size calculators, triangular-arbitrage path maths, currency indices), which compute on rates rather than simply converting them.

NBKR Kyrgyzstan FX API
Live official foreign-exchange reference rates from the National Bank of the Kyrgyz Republic (NBKR), read straight from the bank's published fixing — no key on the data, nothing cached, nothing stored. Get every currency the NBKR fixes against the Kyrgyzstani som (KGS) for the day, each normalized to a clean per-unit rate; look one currency up on its own; pull the separate weekly accounting rates (valid for seven days); or convert any amount between two listed currencies by crossing through the som. The som is the base and rates carry the NBKR fixing date. This is the Kyrgyzstan national-central-bank feed specifically — a distinct official source, separate from the other FX, central-bank and market APIs in the catalogue, so treasury, invoicing, payroll and accounting workflows that need the legally-referenced KGS rate can read it directly.
