Inspect an endpoint by `operation_id`, including path, method, parameters, required inputs, `agent_hints`, and `request_body_schema` for JSON-body POST operations.
call_endpoint
Call a Sugra API operation by `operation_id`. Arbitrary path calls are no longer supported.
list_toolsets
List catalog groups with endpoint counts and descriptions.
list_sources
Show bundled catalog source metadata.
sugra_entity_screen
Screen a name against sanctions and watchlists (Sugra Entity).
sugra_entity_lookup
Composed entity lookup by identifier - `anchor` is `lei` or `vat`, plus the identifier `value`; returns registry identity + screening (Sugra Entity).
resolve_entity
Free text (ticker, company, indicator, coin, currency pair) to a canonical market or macro entity. Ambiguous matches return ranked candidates, never a silent pick.
get_snapshot
Entity plus a named recipe to one composed current view with freshness, provenance, coverage, and billing blocks. Composed calls charge a fixed recipe cost (1-2 requests) from the daily quota.
get_timeseries
Entity plus metric (`price`, `macro_series`, `etf_flows`, `etf_monthly_flows`) to a bounded series with an explicit downsampling flag. `etf_flows` estimates at filing cadence; `etf_monthly_flows` is the fund's own NPORT-P monthly creations and redemptions.
