XpansivInside Xpansiv
Xpansiv’s CBL is the world’s largest and most active spot marketplace for environmental commodities, with a 90 percent-plus share of exchange-traded spot carbon credits.
Its APX unit is a leading provider of registry infrastructure for energy, power and environmental markets, sitting alongside SRECTrade and the H2OX water exchange.
Xpansiv supplies daily, historical and streaming bid, offer and transaction data by API, with REST and FIX connectivity for trading systems.
Xpansiv is the deepest spot venue and a major registry rail: credits can settle on CBL and be referenced against APX registry entries, while Xpansiv market data gives live spot pricing context for listed projects.
