Bitcoin Reference Rates API

healthy 3,604 Subscribers

The value of one bitcoin expressed across every unit CoinGecko tracks — world fiat currencies, precious metals (gold and silver, troy ounce) and other cryptocurrencies, powered by the public CoinGecko exchange-rates feed, no key, nothing stored. This is the "Bitcoin standard" / unit-of-account view: not a coin's dollar price, but how much of each asset one BTC buys right now — 1 BTC in US dollars, euros and yen, in ounces of gold and silver, and in ether, satoshi and dozens more. The rates endpoint returns every unit with its value and asset type; the rate endpoint returns one specific unit (gold, the euro, ether); the groups endpoint splits the units into fiat, commodity and crypto so you can see what a bitcoin is worth across asset classes at a glance. This is the Bitcoin-denominated reference-index cut — distinct from the coin-price converters, the market-overview and the per-exchange ticker APIs in the catalogue.

Crypto Treasury API

Live data on the public companies that hold Bitcoin and Ethereum on their balance sheets, from the public CoinGecko feed. Rank every public company by how much of the coin it holds, with current and entry value, average entry price, country and share of total supply; get the aggregate corporate holdings, USD value and market-cap dominance; find a specific holder by name, ticker or country; and compare Bitcoin and Ethereum corporate treasuries side by side. The corporate crypto-treasury layer — distinct from price and exchange feeds: it answers who holds how much, and what they paid. Live, with a short 60-second upstream cache.

Yadio Real FX API

Live "real" market exchange rates derived from local cryptocurrency (BTC/USDT) trading. Because they are implied by where people actually buy and sell crypto, these rates track the true street/parallel value of a currency — for stressed currencies (Argentine peso, Nigerian naira, Venezuelan bolívar, Lebanese pound …) this is far from the official rate. The rates endpoint returns one base currency against ~130 currencies plus the BTC price; the convert endpoint converts any amount between two currencies; the btc endpoint returns the BTC price in a chosen currency (the crypto bridge that powers every rate); the currencies endpoint lists every supported currency. Read live, nothing stored. This is a global crypto-implied real-rate layer — distinct from official ECB/central-bank rate feeds and from single-country parallel-dollar APIs.

Bitcoin Stats API

Live Bitcoin on-chain economics and network-activity statistics, built on the open blockchain.com dataset — the macro on-chain layer, not raw address or mempool lookups: a live network snapshot (24h transaction count and USD volume, hash rate, market price and cap, total mined supply, miners' revenue), the historical time series of any curated on-chain metric (active addresses, transaction volume, UTXO-set size, mempool size, miner revenue, fees and more), the catalog of available metrics, and Bitcoin's issuance state (total mined, share of the 21M cap, current block reward and estimated next halving).

Bitcoin Mining API

Live Bitcoin mining and hashrate analytics, built on the open mempool.space dataset — the mining layer, not address or mempool data: the mining-pool dominance ranking by share of blocks mined over a period, the current network hashrate and difficulty plus their history, the history of difficulty adjustments with each retarget's percentage change, and block-reward economics over the last N blocks (total and average reward, fees and transactions).
