Kraken Exchange API

Live market data from the Kraken cryptocurrency exchange, served straight from Kraken's public API — no key, no account, nothing cached. Kraken is one of the oldest and largest crypto exchanges; this reads its order book and trades directly. The ticker endpoint returns the live quote for one or many pairs — the last traded price, the best bid and ask and the spread, the 24-hour volume and VWAP, the 24-hour high, low and open and the change since open, and the 24-hour trade count: XBT/USD trades around its live price with thousands of trades a day. The orderbook endpoint returns the live order book to any depth — the bid and ask price levels with their sizes, the best bid/ask and the spread — the real liquidity behind the price. The ohlc endpoint returns candlestick history at intervals from one minute to two weeks. Pairs can be given the friendly way (BTCUSD, ETHEUR) and it resolves them to Kraken's canonical names. This is the exchange-market-data layer for any trading, charting, arbitrage or bot application. Live from Kraken, nothing stored. Distinct from aggregate-price and other single-exchange APIs — this is Kraken's own ticker, order book and candles. 4 endpoints.

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.

Across Bridge API

Live cross-chain bridge data from Across, one of the largest intent-based bridges, which moves USDC, ETH, WBTC and other assets between Ethereum and its rollups (Arbitrum, Base, Optimism, Polygon, zkSync, Linea, Blast, Scroll and more) using a relayer network and a single unified liquidity pool. The quote endpoint prices a bridge transfer — the relayer capital fee, gas fee, LP fee, total fee, the amount received and the estimated fill time. The routes endpoint lists every supported bridge route (origin chain, destination chain, token). The limits endpoint returns the min and max bridgeable amount for a route. The chains endpoint lists supported chains. Read live from Across, nothing stored. This is Across's own cross-chain bridge fee, route and fill-time layer — distinct from DEX, lending, staking and price feeds.

Balancer API

Live data from Balancer, a leading multi-chain decentralised AMM whose programmable liquidity pools (weighted, stable, gyro, boosted) power swaps and yield across Ethereum, Arbitrum, Base, Polygon, Avalanche, Gnosis, Optimism and more. The pools endpoint returns the top pools by TVL on a chain — each with its type, total liquidity, 24h volume and fees, total APR (with a yield/swap/staking breakdown) and constituent tokens. The pool endpoint returns one pool's full state by id, including swap and holder counts and the full APR breakdown. The token endpoint returns a token's live Balancer price plus its symbol, name and decimals. The tokens endpoint searches the token registry by symbol or name. Read live from Balancer, nothing stored. This is Balancer's own programmable-pool AMM, TVL/volume/APR and token-pricing layer — distinct from constant-product DEX feeds, Curve's stableswap and order-book or perps DEX feeds.
