Xignite

Xignite is a massive, deeply entrenched, and highly formidable B2B enterprise market data provider. While Alpha Vantage and IEX Cloud cater heavily to individual developers and startups, Xignite is the absolute, heavy-duty "engine room" powering some of the largest FinTech unicorns, massive online brokerages, and corporate ERP systems in the world (powering platforms like Robinhood, SoFi, and Wealthfront). The absolute core superpower of Xignite is its "Enterprise-Grade Scalability and Uptime Reliability." When Robinhood experiences a massive surge of millions of retail traders buying GameStop stock simultaneously, the underlying market data API cannot crash. Xignite is built entirely on a highly elastic, AWS-backed cloud infrastructure that guarantees 99.99% uptime and can serve billions of API requests a day with zero latency degradation. Furthermore, Xignite provides staggering breadth. It doesn't just provide US stock prices; it provides highly complex global options chains, esoteric fixed-income bond pricing, global interest rates (LIBOR/SOFR), and master data (CUSIP/ISIN mapping). It is highly favored by massive corporations who need to feed live FX rates directly into their Oracle ERP for currency conversion. For massive enterprise scale and unshakeable reliability, Xignite is an industrial powerhouse.
