Tools & capabilities
Mrmarket.ai tools 8
query_dataThe workhorse. A natural-language financial question in; structured rows and columns out. Screens, rankings, comparisons, time-series, cohort studies, and event studies are all single calls.fetch_pageThe continuation. When a `query_data` result is too large for one response, page 1 comes back with a `pagination.next_cursor`; pass that cursor to `fetch_page` to retrieve the rest. It runs no new query, so it never costs credits — the original `query_data` is charged once.describe_dataThe data catalog. Browse categories and fields, or search for a specific metric, before composing a question.get_symbolsFast ticker, sector, and industry resolution. Name to ticker, sector membership, or the full universe in under 50ms.getting_startedA structured orientation tour with verified example prompts, grouped by use case.recent_queriesYour recent queries, for context and re-runs.get_account_statusConnected account, plan tier, credit balance, and rate limits. A useful first call in any new session.report_issueFlag a result that looks wrong or a feature that is missing. Pass the `query_id` from the response so the trace can be investigated.
