About

Massive is a market-data infrastructure platform built to provide real-time and historical financial data to developers, startups, and trading firms. It delivers institutional-grade market data across stocks, options, indices, currencies, and futures, all via a streamlined API, WebSocket, flat-file S3 access, or SQL query interface. The platform emphasizes low latency, direct connectivity to major exchanges (NYSE, NASDAQ, CBOE, OTC), and data normalization to eliminate survivorship bias and outdated pipelines. Massive positions itself as “modernizing Wall Street” by removing legacy bottlenecks and providing the same quality of market data typically reserved for large institutions, but now accessible to any app builder. The platform also includes extensive documentation, client libraries in Python, JavaScript, Go, and Java, tutorials, and example projects to accelerate integration.

Pros & Cons from Real Users

Pros

  • - The response time on the API requests is pretty good, so it is fast enough. There are .NET libraries available to code with.
  • -It is cheap. -It is reliable w/ rarely any downtime. -exactly what I need as a personal investor. -It is a great alternative to having to pay a lot more elsewhere for only data I need (unlike Bloomberg where I would need to pay 25K a month for stuff I wouldn't need).
  • - ability to request data using HTTP json api. - integration with python pandas analytics framework.

Cons

  • - Far too many symbols missing from their system. - Customer service doesn't really listen to their customers. - Some of the usage API calls are not working correctly. - They won't let you talk to a manager when you're having issues with customer service.
  • -some data missing but the team is quick to act and fix. -refund policy kinda stinks.
  • - hidden fees, for example to get even delayed NASDAQ stocks intraday data you need to apply in another company and pay 250$/year - no moneyback after above issue
