mempool channel, with the most recent 30 days of history and 50,000 credits a month, so you can build and test an integration before you pay for volume.
What Free includes
Free includes every market, route, schema and served depth: Hyperliquid families expose L4 where covered, and Lighter exposes L3. Plans differ in capacity and in Free’s 30-day history window, not in which routes or schemas you can call. A Free request or replay must fall inside the most recent rolling 30 days and span at most 30 days; older history is out of range on Free. On any plan, a request also depends on what is stored for the selected symbol and schema.
Get started on Free

2
Make your first request
Follow the Quickstart and confirm
success, data and meta.request_id in the response.3
Move to the route your job needs
Check the market type and symbol on Venue coverage, then call that route for a window inside the last 30 days.
4
Check quality and limits before looping
Check freshness and coverage on Data quality, and size the loop to Free’s request rate, concurrency and credits on Rate limits.
When to upgrade
Move to a paid plan when a job needs history older than the most recent 30 days, more monthly credits, a higher request rate, more concurrent queries, faster standard replay, larger Data Catalog exports, Webhook Alerts delivered to a receiver of your own, or the livemempool channel, which comes with Pro, Scale and Enterprise. Build and above keep the full retained archive. Compare plans on Rate limits.
