What the API serves today

Measured on production on 18 and 19 September 2026. The fills counter, /fills/count, returned 4,051,130,410 on 19 September 2026.

Field availability by period

Older fills carry fewer fields. The table below comes from 1,000-row samples taken in each period; a field marked “empty” is returned as null (or 0 for tid, a zero hash for hash). If you compute fees or match both sides of a trade by tid, start on 25 May 2025 or later.

The 2024 trade archive

Before the fills archive, Hypedexer indexed Hyperliquid trades: This archive is freely available for the community.

Free public export

Any wallet’s trade history can be exported at no cost, as CSV or JSON: This dataset is provided freely as a public good for the Hyperliquid ecosystem: researchers, analysts, and builders can use it without restriction.

For Scale & Enterprise users

Historical data (prior to March 2025) is exclusively available on Scale & Enterprise plans. If your project requires:
  • Programmatic access to the full archive via API: use the start_time / end_time parameters on /fills/user/{user_address} to query historical fills
  • Custom time ranges or filtered exports
  • Ongoing incremental updates integrated into your pipeline
  • Dedicated support for data ingestion
/fills/ and /fills/user/{user_address} both return data before March 2025 when you pass start_time and end_time. Other indexed endpoints start later: see the coverage notes on each page.
Contact us to discuss your requirements. We work directly with teams that need production-grade access to this dataset.
