History before the live tail (~1 h) from the history store, the rest live from Hyperdash's workers. A full page returns next_cursor (pass it with nothing else); with no next_cursor, poll again with start_time = meta.end_time. One query returns at most your plan's wallet-list cap across its pages (Growth 500, Scale and Enterprise 1,000); a query cut there ends with meta.truncated = true and no next_cursor: start a new one from the last row's time. meta.start_time / meta.end_time = the window this page covers: rows are complete in it outside meta.gaps ([{from, to}] not proven, e.g. a worker restart). meta.live_to = the live feed's newest block time (meta.as_of), meta.stale = true when it lags > 15 s. Growth plans and above. Pricing: base + per row.
