gap null. If resuming would be undone within seconds, because the plan has no webhook delivery or today’s budget is already spent, the request is refused with the reason rather than granted and reversed. Your own on and off switch is never touched by a resume. Authenticate with an API key or a signed-in dashboard session. Costs no credits.

"description": "Selects the 2026-10 response contract. Send `2026-10-01`; any dated version on or after it selects the same shapes. Without the header every response keeps its existing shape. With it:\n\n- The data quality routes, `/v1/status/coverage` and `/v1/symbols` answer the standard `{success, data, meta}` envelope.\n- Record times that are integer milliseconds by default become RFC 3339 UTC strings with millisecond precision, and the integer moves to a `*_ms` field: L4 resting-order `timestamp` (`timestamp_ms`), CVD buckets, HIP-3 oracle reads, Lighter and Lighter on Robinhood Chain liquidations and liquidation volume. Levels and trigger-levels `snapshot_ts` become RFC 3339 with `snapshot_ts_ms`.\n- Error bodies carry the contract `error_code` names: `invalid_parameter` instead of `invalid_query_params` and `invalid_path_params`, `historical_depth_exceeded` instead of `history_window_exceeded`, and `historical_range_exceeded` instead of `request_range_exceeded`; a malformed cursor that fails to parse answers 400 `invalid_cursor` instead of `invalid_query_params`. With `0xArchive-Version: 2026-10-01`, malformed cursors on trades, liquidations, L2 and L4 diffs, order history, TP/SL and order-flow routes answer 400 `invalid_cursor`. Without the header, the first six route families treat a malformed cursor as no cursor and return the first page; order flow answers 400 `invalid_query_params`. Malformed trade time inputs answer 400 `invalid_time_range` with the header and 400 `invalid_query_params` without it.\n\nThe response echoes the selected version in its own `0xArchive-Version` header.",
