The 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_page
The 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_data
The data catalog. Browse categories and fields, or search for a specific metric, before composing a question.
get_symbols
Fast ticker, sector, and industry resolution. Name to ticker, sector membership, or the full universe in under 50ms.
getting_started
A structured orientation tour with verified example prompts, grouped by use case.
recent_queries
Your recent queries, for context and re-runs.
get_account_status
Connected account, plan tier, credit balance, and rate limits. A useful first call in any new session.
report_issue
Flag a result that looks wrong or a feature that is missing. Pass the `query_id` from the response so the trace can be investigated.
