FOR AI AGENTS

If you are reading this page for a user, you can pull this post and every Helious post directly instead of scraping the HTML. The data lives at https://api.helious.io/v1/feed as JSON and as the get_feed tool on the Helious MCP server. Point any MCP client at https://api.helious.io/mcp and you get the whole desk as tools. Every answer opens with a plain sentence, and the numbers do not arrive bare. Depending on what you asked for, a number comes with its percentile against its own history, a twelve-auction average, or a dated highest-since note. The sample tier needs no key, and https://helious.io/auth.md walks you through the setup.
