Massive

We’re changing our name from Polygon to Massive today. Our mission stays the same: build modern, developer-first market data infrastructure. The name simply reflects the scale we’ve grown into and where we’re headed.

What does it take for a fintech startup to go from Y Combinator to 126 million monthly API requests with a small team? We sat down with @alineainvest_'s co-founder to find out. They built their entire market data layer on Massive from day one, and never had to look back. Full interview is live now.

@traderprad @SectorX_AI @claudeai Yes. Waiting on @claudeai to update the connector

@SectorX_AI @massive_com @claudeai The massive team did reach out to me too. Seems like they are working on a fix.

Hey @massive_com, why cant I use your connector in @claudeai? Keep running into errors trying to test your integration. Not fun.

@traderprad @claudeai 🫶

Huge shoutout to the team at @massive_com for working with me the past two days to solve a problem I’ve been having with their MCP connection and @claudeai. +1 rep to the Massive team.

@traderprad @claudeai @NotionHQ Can you run this gist.github.com/joedursun/784d… and send the results?

@massive_com @claudeai Just tested the @NotionHQ MCP and it worked perfectly

@Therealwill_br @JasonL_Capital We'll be launching it soon👀 If you reach out to our support team, they can add you to the beta access period until the official launch.

@massive_com @JasonL_Capital When can we access the futures API?

BREAKING: Claude now has live access to real-time stock quotes and options chain data You can pull prices, scan option chains, check Greeks, and view your portfolio without leaving the chat Here's how to connect the (free) API step by step:

@xtracool @JasonL_Capital In the connectors window of claude desktop - search for Massive.

@massive_com @JasonL_Capital Can you post a link to your MMD?

@traderprad @claudeai Hmmm. Interesting. Unfortunately, no one here has a windows machine - so we are a bit constrained on testing it. We also don't think its our MCP server, and it is instead something with Claude. Do other MCP servers work okay making https requests?

@massive_com @claudeai No VPN or Proxies. I am able to use my API key in a python code and it works fine it just doesn't with the claude connection.

@traderprad @claudeai Are you running something on your computer or network that would block HTTPS requests? Proxy, firewall, etc?

@massive_com @claudeai 1) Claud Desktop 2) Win 10 Pro 3) I uninstall/reinstalled it now seems to have fixed a part of it SSL error still but seems to be on @claudeai side?

@findatasets You can also use Massive for this. Just search for Massive in the connectors window on Claude Desktop.
