9 dialects.
One schema.

Every exchange streams its order book in its own format. We map each one onto the same 13 columns, keep prices as the exact strings sent, and leave fields a venue never provides as null instead of inventing them.

Normalized values are real rows from the published sample hour. Raw messages are reconstructed from those rows and abridged.

Data you can trust with a backtest.

Exchange feeds drop messages, reorder them, and disconnect. We check every update as it arrives and audit every file after it is published, so problems surface in our checks instead of your backtest.

Sequence-checked as it streams
Order book updates are checked against exchange sequence IDs and checksums wherever the venue provides them. A detected gap re-anchors the book from a fresh snapshot.
Re-audited every hour
Every published hour is read back end to end: books are rebuilt and checked for crossings and sequence gaps, and every file for time regressions and duplicate rows.
Two clocks on every row
Nanosecond receive time from our collectors, stored next to the exchange's own event time.
Exact, never rounded
Prices and sizes are kept as the exact strings the exchange sent, so there is no floating-point drift.

Historical market data for agents and researchers

A data API built for reproducible crypto research.

CryptoHFTData collects high-frequency public market feeds from major spot and derivatives exchanges, normalizes them into a consistent schema, and publishes research-ready hourly Parquet files. The archive includes tick-level trades, full L2 order book updates and snapshots, funding and mark-price records, open interest, and liquidation events. Researchers can use the same field conventions across venues instead of maintaining a separate parser for every exchange.

Choose browser, REST, Python, CLI, or bulk-file access

Start without credentials by exploring public datasets or making a rate-limited REST download. For repeatable workflows, create a free account, generate an API key yourself, and exchange it for a short-lived bearer token. The Python package reads the published files into data frames, while the OpenAPI contract, agent skills, and MCP metadata let automated clients discover supported operations before they call them. Every dataset page documents coverage, schema, known caveats, and an example request.

Verify availability before running a backtest

Exchange symbols and feed availability change over time. Query the symbols endpoint for the requested venue and data family, inspect the live ingestion status, and keep the exact exchange, date, hour, symbol, and data type in each research artifact. This produces an auditable input path and avoids silently substituting a similar market. Developer documentation explains authentication, rate limits, versioning, error handling, and flat-file access for both people and software agents.
