API marketplace

A live forex volatility analytic as an API, computed from European Central Bank daily reference rates. 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. Distinct from raw exchange-rate and currency-strength APIs — this is the realised-volatility (risk) measure.

Live crypto long/short trader-positioning sentiment as an API, streamed from the Bybit v5 public account-ratio feed. For any USDT perpetual futures contract it returns the share of accounts positioned long versus short (buy/sell ratio) and the derived long/short ratio — either the latest reading or a full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets. The crowd-positioning signal traders use to spot one-sided, over-leveraged markets. Look up by symbol or base coin, pull history, or list tradable symbols. Live, no key. Distinct from funding-rate, price and open-interest APIs — this is the account long/short sentiment.

A live currency strength meter as an API — it ranks 30+ major currencies by how much each has strengthened or weakened against the whole basket over a chosen period, computed from European Central Bank reference rates. Pull the full strength ranking, one currency's strength with its rank and per-pair changes, or any pair's cross-rate and period change. The classic dashboard forex traders watch, delivered as clean JSON. Distinct from raw exchange-rate and conversion APIs — this is the derived strength analytic.

Live crypto perpetual funding rates and derivatives data as an API, streamed from the Bybit v5 public market feed. For every USDT perpetual futures contract: its symbol, last / mark / index price, the current funding rate (per interval, plus percentage and annualised), the next funding time, open interest, 24-hour volume and turnover, and 24-hour price change. Look a contract up by symbol or base coin, rank contracts by funding, open interest, turnover or price move — a ready-made signal for crowded longs and shorts — search, or list them all. Built for trading, quant, dashboard and signal apps. Distinct from spot-price and on-chain data.

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. This is the index-membership and sector-classification reference — not live prices (finance-api), SEC filings (edgar-api) or the global legal-entity register (companies-api). Served from memory — always fast.

The ISO 4217 currency-code register as an API — not foreign-exchange rates, but the metadata a checkout or accounting system needs to handle money correctly. Each currency carries its 3-letter alphabetic code, 3-digit numeric code, official name, the number of minor units (decimal places, e.g. JPY 0, USD 2, BHD 3) and the list of countries that use it. Look a currency up by alphabetic or numeric code, find the currencies a country uses, search by name, or list the whole register. Bundled and served from memory — always fast, no key needed upstream.
