#swap

Live carry-trade and rollover analytics that FX traders run before borrowing a low-yield currency to buy a high-yield one, computed on demand from the interest rates you pass in — no key, no cache, nothing stored. The carry endpoint returns the interest-rate differential, the carry income over a holding period, the financing-adjusted yield and the leveraged return on margin, so you see exactly what a position earns. The rollover endpoint returns the daily, weekly and monthly swap — positive when you receive carry, negative when you pay it — the number a broker debits or credits each night. The breakeven endpoint returns how far the spot rate can move against the position before the carry is wiped out: the cushion the carry buys you, and the break-even spot level. This is an interest-rate and carry engine, distinct from pip and lot calculators and price tools: it turns two yields, leverage and time into the income and the risk cushion of a carry trade. The carry trade is one of the most-used FX strategies (think funding in yen to hold a higher-yielding currency), and these are the numbers behind it. Computed locally and deterministically, so it is instant and private. Ideal for FX dashboards, strategy back-tests, position sizers and trading tools. Rates are annual percentages (5.5 = 5.5%). Live, nothing stored. 3 compute endpoints. For live policy rates feed them in from a central-bank or rates API.

Live DEX-aggregator swap quotes from KyberSwap, which routes a trade across every decentralised exchange and liquidity pool on a chain to find the best output. The quote endpoint prices a swap between two tokens on Ethereum, Arbitrum, Base, Optimism, Polygon or BNB Chain — it returns the amount received, the USD values in and out, the price impact, the estimated gas cost and the DEXs the route passes through. The tokens endpoint lists the supported tokens per chain. The chains endpoint lists supported chains. Read live from KyberSwap, nothing stored. This is KyberSwap's own multi-chain EVM swap-routing and best-price layer — distinct from single-DEX feeds and from Solana swap aggregators.

Live data from Jupiter — the leading DEX aggregator on Solana — served from its public API as clean JSON, no cache. Get the live USD price, on-chain liquidity and 24h price change for any Solana token mint (one or many at once); get the best swap route Jupiter finds between two token mints for a given input amount — the output amount, price impact and number of routing hops, the heart of the aggregator; or search Solana tokens by symbol, name or mint and get the top match's price, liquidity, market cap, decimals and holder count. Read live from Jupiter, nothing cached. This is Jupiter's own Solana swap-routing, token-price and token-search layer — distinct from EVM on-chain explorers, other DEX/DeFi feeds and generic price APIs: the live routing and pricing engine of Solana's biggest swap aggregator.
