Minute-level klines, funding history, liquidations, daily market snapshots and a 2020→now regime archive — cleaned, gap-checked Parquet files plus a REST query API. One subscription instead of a data pipeline.
Coverage as audited July 2026 — the index endpoint always has the live per-symbol ranges.
| Dataset | Coverage | Since | Format |
|---|---|---|---|
| 1m klines — Binance | 450+ USDT-perp markets, complete 1,440-bar day files, volumes re-verified against Binance | 30 Mar 2026 | daily .parquet |
| 1m klines — Hyperliquid | Every Hyperliquid perp (229 assets) | 30 Mar 2026 | daily .parquet |
| Deep klines — Hyperliquid | 1d candles back to HL's 2023 launch; 1h/4h several months back | 2023 | monthly .parquet |
| Funding — Hyperliquid | Hourly funding rate, all perps — also queryable via the REST endpoint | May 2023 | monthly .parquet + API |
| Funding — Binance | Funding + open interest + mark price, all markets | 30 Mar 2026 | daily .parquet + API |
| Liquidations | Per-symbol long/short liquidation flow, all Hyperliquid perps | 30 Mar 2026 | daily .parquet |
| Daily market snapshots | The full /daily payload per day: market health, derivatives, sentiment, macro, ETF flows, cycle indicators | 2 Mar 2026 | JSON |
| Market regime history | Hourly 6-state HMM regime probabilities, full market scope | 2020 | bulk .parquet |
Honest limits: liquidation history begins 30 Mar 2026 — no exchange publishes older per-account liquidation data, so nobody can backfill it. Hyperliquid's API only serves ~4 days of 1-minute candles, which is why the minute archive grows forward from when we started capturing it.
One call returns the full archive index — every data type, symbol, exchange and date range.
Request pre-signed URLs for exactly the files you want and pull them straight into pandas / polars.
Or skip files entirely — the REST endpoints serve klines, funding and liquidations with time-range filters.

Regime history: 2020 (hourly). Hyperliquid funding: hourly since May 2023; HL daily candles to its 2023 launch. Minute klines, liquidations and daily snapshots grow forward from March 2026 — no exchange serves historical minute data or liquidation history, so those can only be captured live.
Parquet (loads straight into pandas / polars) via pre-signed URLs, plus REST query endpoints with time-range filters. Daily snapshots are JSON.
Yes — the same key works via the MCP server and REST, an agent can subscribe itself via x402, and /archives/index is a machine-readable catalogue of every dataset and date range.
You can. Binance publishes its raw kline history in a requester-pays AWS S3 bucket — pulling the archive cost us roughly $40 in AWS fees alone, before writing a single line of code. Then you still have to dedupe partial candles, verify volumes, fill exchange-outage gaps, convert to a usable format, and host the result somewhere your backtester can reach.
We did that once, keep it updated daily, and re-verify candle volumes against the exchange. Pro Plus includes the whole archive — pre-signed Parquet downloads and a query API.
