#history

Live detail and full APY/TVL history for any DeFi yield pool, keyless. Unlike current-yield screeners, this is the per-pool time dimension: look up a pool by its id for its current APY (base + reward), TVL, risk flags and forecast, then pull its APY and TVL over time to judge whether a headline yield is sustainable or a fading incentive. Search 15,000+ pools by token, project or chain to find a pool id. Live, nothing stored. The yield-history layer for farming, allocation, backtesting and risk apps — distinct from current-yield lists, this tracks a single pool yield through time.

Historical price for any crypto token by its on-chain contract address, keyless. Unlike current-price APIs, this is the time dimension: a price chart over any window, the price at any past date or timestamp, the percentage change over a period, and the token first-ever recorded price. Works for any token on any chain by chain:address (and coingecko:id), covering long-tail tokens centralized APIs miss. Live, nothing stored. The token price-history layer for charting, backtesting, accounting, tax and analytics apps — distinct from current-price and coin-slug APIs, this prices a token HISTORY by contract address.

Live historical daily prices (OHLC) for US stocks from Nasdaq — no key, nothing stored. The price-history-and-charting view of a stock: the daily open, high, low, close and volume going back months or years, distinct from the live-quote, movers, earnings and analyst APIs in the catalogue. The history endpoint returns the daily OHLC time series over a chosen range — 1 month to 5 years, or explicit from/to dates — ready to plot or backtest. The stats endpoint computes the period statistics from that series: the period high and low, the latest close, the total return over the period, the average daily volume and the annualised volatility (from daily log returns). Build charting widgets, backtesting tools, technical-analysis pipelines, performance trackers and risk models on top of real Nasdaq price history. Look up any US stock by its ticker (symbol=AAPL) and a range (1m, 3m, 6m, 1y, 2y, 5y) or explicit from=YYYY-MM-DD and to=YYYY-MM-DD; prices and volumes are returned as clean numbers.
