Use InfinityVolume in your AI assistant

InfinityVolume's dollar-volume figures, as a connector your AI assistant can call: how much traded in 13 stock markets and in their sectors, against each one's own normal; one company's activity against its own history and its sector; the most traded US companies; and InfinityVolume's public articles. Ask in your own words; each answer states its window and date and links to the page it comes from.

The server address

https://www.infinityvolume.com/api/mcp

Market totals, breadth, sector shares and one company's activity cover every market the site shows; the sector rankings, cumulative totals and most traded list cover the US. Figures come inside sentences, never as tables or daily lists. Free, read only, no account needed. No prices.

Limits

Up to 60 calls a minute and 2,000 a day from one address, and an overall ceiling for everyone. Past a limit, the answer says how many minutes to wait. Updated after each session. US figures are provisional in the evening and final the next morning.

What we log

Each call is logged with the tool, what was asked of it, the time, the AI app's name and version, and whether it answered, so we can keep the service working and see which tools are used. Your IP address is used only to apply the limits and is not kept; no user agent is stored, and it sets no cookie. Each logged call is kept 30 days, then only daily counts remain. Clicks on the links in its answers are counted as daily totals. We do not share it with anyone or offer it for sale.
