## Data sources

| Source | What it provides | Access |
|--------|-----------------|--------|
| **Direct recent-price APIs** | Price-only OHLCV bars for the current and previous exchange-local calendar dates. US minute bars use `stocks/bars` with `interval: "1min"`; China minute bars use `cn-stocks/bars_1min`. | `POST $API_URL/api/data/stocks/bars`, `POST $API_URL/api/data/cn-stocks/bars`, or `POST $API_URL/api/data/cn-stocks/bars_1min` — see `data/SKILL.md` |
| **Rebyte financial data lake** | US: daily + 1-minute bars, news, SEC-filing fundamentals, splits, dividends, short data, ticker universe, IPOs. CN A-shares: daily + 1-minute bars, valuation snapshots, financial statements, money flow, unusual-move disclosures. | Read-only SQL via `POST $API_URL/api/data/financial/sql` — see `data/SKILL.md` |
| **News archive** | US equity news coverage back to 2016, searchable by meaning | `POST $API_URL/api/data/research/news` — see `data/SKILL.md` |
| **Research library** | ~4,300 long-form articles from 13 investment research publications (SemiAnalysis, SemiVision, MacroCharts, Capital Wars, Citrini, Doomberg, Michael J Burry and others), 2020 to today. Primary analysis by named practitioners — use it for theses, debates, and mechanisms. | `POST $API_URL/api/data/research/search`, then `/context` or `/article` — see `data/SKILL.md` |
| **SEC EDGAR** | Full filing text (10-K, 10-Q, 8-K), filing sections, insider (Form 4) trades | `edgartools` Python library — see `references/sec-edgar.md` |

**Route by freshness.** Use the direct APIs for "current", "today", "latest
price", and recent intraday questions. Their range is fixed server-side to the
current and previous calendar dates in `America/New_York` (US) or
`Asia/Shanghai` (CN); callers cannot widen it. Use the lake for every older or
non-price fact. The US response exposes Polygon's `upstreamStatus` (for example
