Live US Treasury yield curve as an API — US government bond yields across the curve, served from Yahoo Finance. It returns the current yield (in percent) for the 3-month, 2-year, 5-year, 10-year and 30-year Treasuries with their daily change in basis points, the shape of the curve (steep, normal, flat or inverted), and the key spreads traders and economists watch — the 10y-2y and 10y-3m spreads, whose inversion has preceded every modern US recession — plus an inverted flag. Get the whole curve, a single maturity's yield, or the spread between any two maturities. The interest-rate and recession-signal layer for trading, macro-research and dashboard apps. Live, no key, no cache. Distinct from US Treasury fiscal-data APIs (which track national debt and issuance) — this is the live market yield curve.

Live crypto tokenomics — supply and dilution metrics for any cryptocurrency, powered by CoinGecko. For any coin it returns the circulating, total and maximum supply, the percentage of the maximum supply already issued, the market cap and the fully-diluted valuation (FDV), and the market-cap-to-FDV ratio — the share of supply already unlocked — together with the dilution overhang, the percentage of FDV still locked or yet to be minted. It can also rank the top coins by dilution overhang (which assets have the most future supply hanging over them) or by how much of their cap is issued. The supply-and-dilution layer that token research, due diligence and risk dashboards need. Live, no key, no cache. Distinct from price, market-cap and all-time-high APIs — this is the tokenomics analytic.

Live crypto all-time-high tracker as an API — the distance-from-ATH (and distance-from-all-time-low) every crypto dashboard shows, powered by CoinGecko. For any coin it returns the current price, its all-time high with the date and how far below it the price sits now (the headline "X% below ATH"), the days since that high, and the mirror metrics versus the all-time low. It also ranks the top 100 coins by how close they are to — or how far they have fallen from — their ATH, so you can see at a glance which assets are at fresh highs and which are deepest in drawdown. Get a coin's ATH stats, the leaders/laggards board, or search to resolve a coin name to its id. The cycle-and-drawdown layer for crypto, trading and dashboard apps. Live, no key.

Live crypto cross-exchange price comparison and arbitrage spread — the spot price of a coin on the major centralised exchanges at once, served straight from each exchange's public ticker. For any base coin it fetches the spot price from Binance, OKX, Bybit, KuCoin and Coinbase in parallel, returns the per-exchange price table, identifies the cheapest venue to buy and the most expensive to sell, and computes the spread between them — absolute and percentage — the headline cross-exchange arbitrage gap. Get the full price table, the best buy/sell opportunity, or the list of exchanges. Live, no key, no cache. Quotes are USDT (Binance/OKX/Bybit/KuCoin) or USD (Coinbase), within a few basis points.

Live forex market-hours layer — a real-time read on which foreign-exchange trading sessions are open right now and where the liquidity is. The 24-hour forex market runs as a relay of four regional sessions — Sydney, Tokyo, London and New York — and this computes, from the current clock and each financial centre's own timezone (daylight-saving handled automatically), whether each session is open, its local time, and its standard open and close in both local time and UTC. It surfaces the active session overlaps that traders care about — above all the London–New York overlap, the most liquid window of the day — reports whether the overall market is open (it closes over the weekend), and gives a world-clock of the four centres. Deterministic and always live, no key. Distinct from FX rate, strength, volatility, seasonality and signal APIs — this is the market-hours layer for forex, trading and dashboard apps.

Live open-interest history and trend for crypto perpetual futures, served from the Bybit v5 feed. Open interest is the total value of outstanding contracts — its trend, rising or falling alongside price, is the signal traders use to confirm a move or spot a squeeze. For any USDT perpetual this returns the latest open interest in contracts and in USD, how it has changed over your chosen window, the rising / falling / flat trend, and the full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets.
