BIS Effective Exchange Rates (Currency Strength) API

How strong each currency is on a trade-weighted basis, served live from the Bank for International Settlements' open statistics API — no key, nothing cached. An effective exchange rate (EER) measures a currency against a basket of its trading partners' currencies, not just one pair — it is the single best gauge of whether a currency is broadly strengthening or weakening. The BIS publishes nominal and real (inflation-adjusted) EER indices for 64 economies, against a broad (64-economy) or narrow (27-economy) basket, all on a base of 100. The rankings endpoint returns every economy's current EER index, ranked, so you can see the world's strongest and weakest currencies at a glance. The country endpoint returns one economy's EER index with its history and its 12-month change. The movers endpoint ranks the biggest currency gainers and losers over the past year — who has appreciated and who has depreciated most. Everything is the BIS's own compiled data, live, nothing stored; figures are monthly. This is the trade-weighted currency-strength layer for any forex, macro, trade or research app. Distinct from bilateral FX-rate and central-bank APIs — this is effective exchange rates: real and nominal trade-weighted currency strength, from the BIS. 3 endpoints, no key on our side.

Aptos (APT) On-Chain API

Live on-chain data from the Aptos blockchain (APT), a high-throughput Move-based Layer 1, served straight from the official public Aptos fullnode REST API — no key, nothing cached. The account endpoint returns any address's state: its sequence number, authentication key, APT balance and how many on-chain resources it holds. The balance endpoint returns the balance of APT or any coin or fungible asset for an address, handling both the classic coin standard and the newer fungible-asset standard in one call. The resources endpoint lists the Move resource types an account holds — its coins, stores, staking and module data — the structural view of what lives at an address. The transactions endpoint returns the account's most recent transactions with the version, hash, entry function, success flag, gas used and time. The network endpoint returns the live chain state: chain id, the latest ledger version and block height, the epoch and the ledger timestamp. Everything is read live from the fullnode, nothing stored. This is the Aptos on-chain layer for any wallet, explorer, payments, gaming or analytics app. Distinct from the XRP Ledger, Stellar, TRON, EVM and Solana on-chain APIs and from price feeds — this is Aptos account state, balances, Move resources, transactions and ledger health. 5 endpoints, no key on our side.

Bitfinex Exchange API

Live market data from Bitfinex, one of the longest-running crypto exchanges, served straight from its public v2 API — no key, nothing cached. Bitfinex is best known for two things this exposes as clean JSON: deep spot order books, and a peer-to-peer funding (margin-lending) market that few APIs surface. The ticker endpoint returns a trading pair's snapshot: best bid and ask, last price, 24-hour change and percentage, volume, high and low — BTC/USD near $63,000. The funding endpoint returns a currency's lending market: the Flash Return Rate, the best bid and ask lending rates with their loan periods, and the daily rate annualised to an APR — so you can see what lending US dollars or BTC on Bitfinex pays right now, around 14% APR for USD. The tickers endpoint returns the whole exchange in one call, either every trading pair or every funding currency. The trades endpoint returns the live trade tape — the most recent executed trades with price, amount, side and time. Everything is Bitfinex's live venue data, nothing stored. This is the Bitfinex price, funding-rate and tape layer for any trading, lending, charting or market-data app. Distinct from Coinbase, Binance and Kraken venue APIs and from aggregated feeds — this is Bitfinex's own order book, its margin-funding rates and tape. 4 endpoints, no key on our side, real-time.

Swiss National Bank (SNB) FX & Rates API

Live official Swiss monetary data, served straight from the Swiss National Bank's open data portal — no key, nothing cached. The Swiss franc is one of the world's premier safe-haven and reserve currencies, and this exposes the SNB's own published numbers as clean JSON. The rates endpoint returns the SNB foreign-exchange fixing — the monthly-average value in francs of around 25 world currencies (the euro fixed near 0.92 francs in mid-2026), each normalised to the franc value of a single unit. The currency endpoint returns one currency's franc rate with its recent history. The policy-rate endpoint returns the SNB policy rate, the headline interest rate the Swiss National Bank sets to steer the economy, with its history. The saron endpoint returns SARON, the Swiss Average Rate Overnight — the franc benchmark that replaced CHF LIBOR and underpins Swiss financial contracts — with its recent path. Everything is the central bank's own published data, live, nothing stored; figures are monthly. This is the Swiss franc rates-and-FX layer for any forex, treasury, payments or macro app exposed to Switzerland. Distinct from the ECB, Fed, Bank of Canada, Norges Bank, Bank of England, Brazil, Poland and Czech central-bank APIs — this is the franc, the SNB policy rate and SARON. 5 endpoints, no key on our side.

Stellar (XLM) On-Chain API

Live on-chain data from the Stellar network, the open blockchain for payments and asset issuance behind the lumen (XLM), served straight from Stellar's public Horizon API — no key, nothing cached. The account endpoint returns any address's full wallet: its XLM balance and every issued asset it holds — Stellar is the home of anchored stablecoins like USDC, so a wallet shows native lumens alongside its tokens, each with the asset code, issuer and balance — plus the account sequence, sub-entry count and home domain. The payments endpoint returns the account's most recent payments in and out, each with the counterparty, asset, amount and time. The transactions endpoint returns the account's recent transactions with the ledger, fee, operation count, success flag and memo. The network endpoint returns the live state of the network itself: the latest ledger, the base fee and the fee percentiles and ledger capacity that tell you how congested the network is. Everything is read live from Horizon, nothing stored. This is the Stellar on-chain layer for any wallet, anchor, exchange, payments or analytics app. Distinct from the XRP Ledger, EVM and Solana on-chain APIs and from price feeds — this is Stellar account state, multi-asset balances, payments and network health. 4 endpoints, no key on our side.

Czech National Bank (CNB) FX API

Live official Czech foreign-exchange fixing, served straight from the Czech National Bank's open API — no key, nothing cached. The CNB declares one official rate per currency every working day. The rates endpoint returns the whole daily fixing — around 30 world currencies against the koruna (CZK), each with the country, the unit amount it is quoted per and the rate — and accepts a date so you can pull the official fixing for any past working day. The currency endpoint returns one currency's rate, normalised to the koruna value of a single unit, for the latest day or a chosen date — the US dollar fixed around 21 koruna in mid-2026. The convert endpoint turns an amount from any currency into any other, crossed through the koruna at the official fixing, on the latest day or a historical date. The history endpoint returns a currency's official rate over the last several working days. Everything is the central bank's own published fixing, live, nothing stored. This is the Czech koruna FX layer for any forex, payments, e-commerce, accounting or treasury app operating in Czechia and Central Europe — and a clean source of historical FX by date. Distinct from the ECB, Fed, Bank of Canada, Norges Bank, Bank of England, Brazil and Poland central-bank APIs — this is the koruna and the CNB daily fixing, queryable by date. 5 endpoints, no key on our side.

XRP Ledger (XRPL) API

Live on-chain data from the XRP Ledger (XRPL), the decentralized blockchain behind XRP, served straight from public XRPL nodes by JSON-RPC — no key, nothing cached. The account endpoint returns any address's core state: its XRP balance, transaction sequence, the number of objects it owns, and its account flags and domain — the genesis-era account rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh holds tens of thousands of XRP. The balances endpoint returns the full wallet: the XRP balance plus every issued-currency trustline (token or stablecoin) the account holds, with the issuer, currency and amount, decoding hex currency codes to readable tickers. The transactions endpoint returns the account's most recent ledger activity — payments, DEX offers, trustline changes — each with its hash, type, amount, fee, result and time. The server endpoint returns the state of the ledger itself: the latest validated ledger index and age, the base and per-object XRP reserves, the current fee and the node software version — the network health a wallet or explorer needs. Everything is read live from the XRPL, nothing stored. This is the XRP Ledger on-chain layer for any wallet, explorer, exchange, payments or analytics app. Distinct from EVM and Solana on-chain APIs and from price feeds — this is XRPL account state, token balances, transactions and ledger health. 4 endpoints, no key on our side.

Narodowy Bank Polski (Poland) FX & Gold API

Live official Polish foreign-exchange and gold data, served straight from the National Bank of Poland's open API — no key, nothing cached. The rates endpoint returns the NBP daily fixing: the official mid rate of every world currency against the zloty (PLN), table A for the common currencies and table B for the exotic ones, with the bulletin number and date. The currency endpoint returns one currency's mid rate, its bid and ask from the trading table, and its recent history — the US dollar fixed at about 3.69 zloty in mid-2026. The bidask endpoint returns the full trading table (table C): every currency with its buy and sell rate and the spread between them. The gold endpoint returns the NBP accounting price of gold — one gram of pure gold in zloty — with recent history, around 509 zloty a gram. The convert endpoint turns an amount from any currency into any other, crossed through the zloty at the official fixing, so you can convert USD to EUR or JPY to PLN in one call. Everything is the central bank's own published data, live, nothing stored.

The ticker endpoint returns a pair's full snapshot: last price, best bid and ask, 24-hour open, high and low, the VWAP, the 24-hour percentage change and base volume — BTC/USD around $63,300 and BTC/EUR around €54,900.
