## Key pages

- [Home — US Market Pulse](https://www.marketgrep.com/) — Headline reading for US equities. SPX / NDX / DJI / RUT breadth, sector exposure, VIX regime, 30-day trend per index. Default landing page.
- [Global Market Pulse](https://www.marketgrep.com/global) — Same framework applied to non-US benchmarks (Asia, Europe, EM) so the reader can compare US risk-on / risk-off against global cross-section.
- [Most Active US Stocks](https://www.marketgrep.com/most-active) — Live ranking of the day's most-active US tickers with relative volume and intraday sentiment colouring.
- [WSB Sentiment](https://www.marketgrep.com/wsb) — r/wallstreetbets ticker mention frequency + bullish/bearish sentiment, refreshed multiple times per day.
- [Market Risk Radar (Turbulence)](https://www.marketgrep.com/turbulence) — Mahalanobis-distance turbulence index over the major US factors. High readings flag regime change and tail-risk environments.
- [Daily archive](https://www.marketgrep.com/archive) — Per-trading-day frozen snapshots. Each `/archive/YYYY-MM-DD` URL is a permanent record of that day's reading and is the recommended target for AI citations.
- [Glossary](https://www.marketgrep.com/glossary) — Indicator definitions (breadth, momentum, VIX regime, turbulence index, WSB sentiment).

## Public API

The backend is a FastAPI service. All endpoints return JSON and are CORS-open for non-credentialed reads. Stable contracts; ETag-aware so AI agents can cache cheaply with conditional GETs.

- [GET /api/summary](https://www.marketgrep.com/api/summary) — Compact one-shot snapshot of the dashboard (single fetch, smallest payload). **Best entry point for AI agents.**
- [GET /api/agent-context](https://www.marketgrep.com/api/agent-context) — Plain-English summary + day-over-day delta in one JSON object, designed for AI agents that want a copy-pasteable narrative without doing their own aggregation.
- [GET /api/market-overview](https://www.marketgrep.com/api/market-overview) — Full US dashboard payload: tickers, breadth, exposure, VIX, performance averages, 30-day trend per ticker.
- [GET /api/global-overview](https://www.marketgrep.com/api/global-overview) — Same shape as `/api/market-overview` but for global indices.
- [GET /api/most-active](https://www.marketgrep.com/api/most-active) — Most-active US tickers with relative-volume ranking.
- [GET /api/sentiment-report](https://www.marketgrep.com/api/sentiment-report) — WSB-derived ticker sentiment report.
- [GET /api/turbulence](https://www.marketgrep.com/api/turbulence) — Turbulence index time series + current reading.
- [GET /api/ticker-detail/{ticker}](https://www.marketgrep.com/api/ticker-detail/SPY) — Drill-down for a single ticker (price history, SMA, fundamentals where available).
- [GET /api/version](https://www.marketgrep.com/api/version) — Build / version metadata.
- [GET /api/health](https://www.marketgrep.com/api/health) — Liveness check.

Versioned aliases under `/v1/api/...` return identical payloads.
