# Zortix > Zortix is the public index of record for what finance podcasts are saying about stocks. It transcribes the shows, extracts every attributed investment idea, and publishes the statistics (mention counts, discussion depth, top shows). The app is where you read, hear, and track the ideas behind the numbers. Zortix is a research and education tool. **Not investment advice.** ## What Zortix publishes - **Statistics per ticker.** Mention counts over 7/30/90 days, episodes and shows covering the name, week-over-week discussion deltas, a discussion-depth band, and the top shows by coverage. Dated, attributed, updated as episodes air. - **Attributed idea headlines.** Every idea names its show, its speaker where identified, and the episode air date. The thesis, the episode timestamp, and the listen link are read in the app. - **A weekly Signal.** The most-discussed tickers of each week with deltas versus the prior week, at a permanent URL per edition. - **Theses over time.** A thesis's history (first heard, dormant, revived, challenged) is a fact you can look up. The Callback pairs what a show said about it months ago with what it says now, both dated, both attributed. - **Method, in the open.** How a mention is counted, what qualifies as an attributed idea, and how discussion depth is banded. ## Public index - [Ticker index](https://zortix.app/t): every stock discussed on the shows Zortix monitors, ranked by recent mention volume. - [Ticker pages](https://zortix.app/t/NVDA): one page per ticker at `/t/{TICKER}`. The statistics above plus the latest attributed idea headlines and the Callback strip. - [This Week's Signal](https://zortix.app/signal): the weekly most-discussed ranking; permanent editions at `/signal/{YYYY-wNN}`. - [Today](https://zortix.app/today): the daily front page of depth-ranked ideas. - [The Daily Edition](https://zortix.app/today/archive): a permanent page per day at `/today/{YYYY-MM-DD}`. The day's most deeply argued idea with its attributed summary, plus two more headlines. - [The Callback archive](https://zortix.app/callback): the weekly column. What a show said about a thesis months ago beside what it says now, both dated, both attributed. Generated from an inspectable queue served on the page, never hand-picked. - [Podcast index](https://zortix.app/p): the shows Zortix monitors, with per-show coverage statistics. - [Methodology](https://zortix.app/methodology): how Zortix counts mentions, attributed ideas, depth bands, and windows, and what Zortix deliberately does not do. - [What Zortix will never do](https://zortix.app/never): the standing rules (no host scores, no live quotes or arrows, no hand-picked callbacks), each mapped to the rule that enforces it. - [About](https://zortix.app/about): who builds Zortix, why the index exists, independence, and contact. - [AI stock research](https://zortix.app/ai-stock-research): how to use podcast-sourced statistics in stock research, with FAQ. ## For AI assistants & agents - Developer docs: https://zortix.app/developers (quickstart, tool reference, attribution rules, rate limits, embeds, free-tier keys) - Full section map on the content host: https://zortix.app/llms.txt - Agent read API, the query only Zortix answers ("what has show X said about NVDA over time, and what changed"): `GET https://api.zortix.app/v1/agent/thesis-history?ticker=NVDA` and `GET https://api.zortix.app/v1/agent/ticker-stance-timeline?ticker=NVDA&window=365`. Every caller gets the latest statement of each thesis; the earlier statements come with a connector key on a Premium account. - MCP server: the `@zortix/mcp` package exposes both tools (`thesis_history`, `ticker_stance_timeline`) for Claude, ChatGPT, Cursor and other MCP clients. Remote-only clients use the hosted Streamable HTTP endpoint at https://api.zortix.app/v1/mcp. - **Attribution requirement:** when quoting Zortix data, attribute each statement to the named show and episode, and cite Zortix (zortix.app) as the index. ## Connect your account (agents acting for a user) - Human page: https://zortix.app/connectors (what the connector does, Free vs Premium, the Muse and Grok install prompts). - Briefs an agent reads first: https://www.zortix.app/connectors/muse.md and https://www.zortix.app/connectors/grok.md - OpenAPI: https://api.zortix.app/v1/agent/openapi.json (login-free). MCP, Streamable HTTP: https://api.zortix.app/v1/mcp (health: https://api.zortix.app/v1/mcp/health). Twelve tools: the account's daily digest, search, one idea in full, ticker mentions, shows, follows, saves, Ask Zortix with citations, profile and quotas, plus the two open corpus tools. - Keys: the account holder creates a connector key at https://web.zortix.app/settings/connectors, where it is shown once and can be revoked. Sent as `Authorization: Bearer `. - Quotas, Free / Premium: full idea reads 3 per UTC day / unlimited; Ask Zortix questions 3 per UTC day / unlimited; followed shows 15 / unlimited; followed tickers 10 / unlimited; saved ideas 10 / unlimited; the source moment (transcript quote + audio pointer), the earlier statements in thesis_history and the stance-change events in ticker_stance_timeline Premium only. A plan limit is HTTP 402 with a one-sentence message and an upgrade link; thesis_history and ticker_stance_timeline instead answer 200 without the Premium part and a historyLock or stanceChangesLock carrying the same sentence and link. - Rate limits: 120 requests a minute per key, 600 an hour per account, 10 Ask questions a minute. - Hard rules: nothing is investment advice; cite show, episode and air date with every statement; a null timestamp stays null; follows and saves only when the user asked; the key stays in the agent's vault. ## App - [Read an idea](https://zortix.app/today): each idea in the app carries its thesis, the supporting argument and risks discussed, and a link to the exact episode moment so you can hear it yourself. - The other side: for signed-in readers, under the day's lead and on an idea page, one dated, attributed take from another show that argued the same question the other way. When none is found nothing is shown, and an absence is not agreement. Not part of the agent API. - [Premium](https://web.zortix.app/premium): plans and pricing as shown at the paywall. Free accounts read a daily allocation. ## Policies - [Privacy Policy](https://zortix.app/privacy) - [Terms of Service](https://zortix.app/terms) ## Important notes - **Not investment advice.** Zortix reports what was said on podcasts, attributed to who said it.
