Data Availability

⚠️90-day retention

We retain 90 days of data per stream (rolling window). Pro can query up to 60 days; Business can query the full 90 days. For some streams, collection started recently so the actual range is still shorter than 90 days. Date ranges in the API are clamped to the earliest available data; requests for earlier dates return empty or clamped results.

Use this page to see when each data stream started and what date range is available. Tables are derived from market_snapshots, market_trades, binance_agg_trades, liquidations, and ingestion_log.

Earliest data by source (market snapshots / candles)

Earliest data by source and interval (candles / snapshots)

Availability can vary by symbol and interval. Examples (subset):

Other symbol/interval combinations follow similar ranges. When in doubt, request a short range or omit start/end to get the most recent data.

Ingestion log (first worker run)

Overall first ingestion log: 2026-03-14 03:36:14 UTC.

How this affects your requests

  • start / end — If you request a range that starts before the earliest data, the API returns data from the earliest available timestamp (or empty if the range is entirely before collection started).
  • Tier history depth — We retain 90 days of data per stream (rolling). Pro can query up to 60 days; Business can query the full 90 days. Free tier limits (14 days across data endpoints) still apply. Until we have 90 days of collection for a stream.
  • Backtesting — For backtests that need long history, note that only Hyperliquid has the longest range (24h from Dec 2025); other sources have days to a few weeks as of March 2026.

For the latest availability, call GET /v1/sources (includes tier requirements) and use the date ranges above when planning queries.
