API marketplace

Live decentralised-exchange trading volume across the whole crypto ecosystem as an API, streamed from the DefiLlama DEX feed. For thousands of DEX protocols: the trading volume over the last 24 hours, 7 days and 30 days, the day/week/month change, the chains they run on, and each one's share of the total DEX market. Rank the busiest DEXes, drill into a single one, see how trading volume is split across chains, or read the market-wide total. Built for crypto, trading and dashboard apps. Live, no key. Distinct from TVL, fees, yield and stablecoin APIs — this is the on-chain trading-activity surface.

A live forex analytic that tells you where a currency pair is trading inside its recent range, computed from European Central Bank daily reference rates. For any pair it returns the period high and low (and the dates they happened), the current rate, and the percentile position in the range (0% = sitting on the low, 100% = sitting on the high) plus the distance from each extreme — the context traders use for mean-reversion and breakout calls. Get a pair's range over a month, quarter, half-year or year, or scan a basket to find what is pinned near its highs or lows. Built for forex, trading and dashboard apps. Live, no key. Distinct from rate, strength, volatility, correlation and signal APIs.

Live FX technical-analysis signals as an API, computed from European Central Bank daily reference rates. For any currency pair it builds the daily cross-rate series and returns the classic indicators traders watch — 20- and 50-day moving averages and their crossover (golden / death cross), a 14-day RSI (overbought / oversold) and momentum — rolled up into a simple bullish / neutral / bearish verdict. Get a pair's signal, its raw indicators with the recent closes, or scan a whole basket for the strongest setups. A ready-made signal layer for forex, trading and dashboard apps. Live, no key. Educational, not financial advice. Distinct from raw-rate, strength, volatility and correlation APIs.

Live DeFi yield-farming APYs across the whole decentralised-finance ecosystem as an API, streamed from the DefiLlama yields feed. For thousands of liquidity pools across every chain and protocol: the current APY split into base and reward, the pool's TVL, its chain, project and token symbol, whether it is a stablecoin pool and its impermanent-loss risk. Rank the top yields with a sensible TVL floor (so dust-pool noise is filtered out), drill into any single protocol or chain, filter to stablecoin pools, or search. Built for DeFi, yield-aggregator and dashboard apps. Distinct from TVL and price APIs — this is the live yield surface. Note: very high APYs are reward-driven and transient; use a TVL floor, the stablecoin filter, or sort by TVL for durable yields.

A live forex correlation analytic as an API, computed from European Central Bank daily reference rates. It measures how the world's currencies move together: each currency's daily appreciation is correlated against every other, so you can see which currencies move in lock-step (don't double up the same risk) and which move opposite (natural hedges). Get one currency's correlations to all others ranked, the coefficient for any pair, or a full correlation matrix for a basket. Risk and diversification input for forex, portfolio and trading apps. Live, no key. Distinct from currency-strength (direction) and FX-volatility (magnitude) — this is co-movement.

For any currency pair it returns the realised annualised volatility — the standard deviation of daily log returns scaled to a year — along with daily-return statistics; for the whole basket it ranks 30+ currencies by their average pairwise volatility, showing who is calm and who is choppy. The risk and position-sizing input forex, options and trading desks need. Look up a pair, rank the basket, or get one currency's volatility profile. Live, no key.

The directory of every security listed on the NASDAQ stock market as an API — the reference a brokerage, stock screener or ticker-validation tool needs to confirm a symbol is NASDAQ-listed and see what kind of instrument it is. For each of 5,400+ securities the API returns its ticker symbol, the full security name and a normalized security type (common stock, ETF / fund, warrant, unit, right, preferred, note or depositary receipt) derived from the listing. Look a ticker up, search by symbol or company name, filter by security type, or list them all with a per-type breakdown. This is the NASDAQ listing directory — distinct from sp500-api (S&P 500 index membership) and finance-api (live quotes). Served from memory — always fast.

The current members of the S&P 500 stock index as an API — the reference a stock screener, portfolio tool or research dashboard needs. For each of the ~500 constituents: its ticker symbol, the company name, its GICS sector and sub-industry, the headquarters location, the date it was added to the index, its SEC Central Index Key (CIK, ready for EDGAR look-ups) and the year it was founded. Look a constituent up by symbol or name, list every company in a GICS sector, search across symbols, names, sub-industries and headquarters, or list the whole index with a per-sector breakdown.
