list_lists
Return all lists owned by the current user, with field and item counts.
get_list
Get a single list by ID. Pass include_items=true to embed all items in the response. Use item_fields to project only specific field_values keys, reducing response size.
get_lists
Fetch multiple lists by ID in a single call. Silently skips IDs that are not found or not owned by the current user. Supports the same include_items and item_fields options as get_list.
get_schema
Get the field schema for a list — the field names and IDs that define the columns. Call this before merge_list to get valid field names for field_values keys, or field IDs for targeted updates.
get_limits
Get the current user's service tier, per-tier limits (max lists, items per list, fields per list), and an upgrade_url. Share the upgrade_url with the user if they are at or near a limit so they can upgrade their plan.
export_data
Export all lists, field schemas, and items for the current user as structured JSON.
