🟢tako_available_data(q, metric, types, label, limit)
Find what data Tako holds on an entity or a metric, and the canonical name it holds it under. Best for: coverage questions themselves, or a metric's canonical name before a priced search. Put a company, person, or place in `q` to list the metrics tracked on it; put a metric in `q` to list the entities it covers. Add `metric` when you know the measure — you get the resolved pair and a ready-to-run `next_call`. Search on the canonical names it returns, not your own phrasing — `tako_search` matches the graph's names, not yours. A name here means the graph tracks it, not that a card exists. If the follow-up search comes back empty, say Tako has no card for it rather than rephrasing the query. Hand a node id to `tako_graph_related` to see what else connects to it.

}🟢tako_contents(urls, max_rows, max_chars, query)
Fetch the full content behind a url: a web page's text, or an exportable Tako card's data rows. Batch up to 10 urls in one call — each one is billed and fails on its own. Fetch only cards that `tako_search` marked `exportable: true`. Rows bill per 1,000 delivered, so set `max_rows` when the recent rows are enough. If a page is long, such as a filing or an annual report, set `query` to get back only the passages that match. Best for: reading one source in full — a page you need to quote, or the rows behind a card you need to compute over.

}🟢tako_graph_related(node_id, relation, q, label, infer_label, ...)
Explore what a graph node connects to — its metrics, the entities a metric covers, competitors, industry, index membership, and sources. Two modes. Pass `node_id` alone for the map: every relation group with its key, label, total, and its first 3 names. Pass `relation` to page one group, where each item comes back with the id that explores it. Read a key off the map rather than guessing — an unknown key returns an empty group, not an error. Best for: expanding a node you already resolved. Resolve a name to a node id with `tako_available_data` first. A metric listed here means the graph tracks it, not that a card exists — `tako_search` is the final check.

}🟢tako_search(query, sources, country_code, locale)
Search Tako's data graph and the live web in one call: many results at once, as structured cards plus web results, with the top card rendered inline as a chart. It finds data; `tako_contents` fetches it. Each card carries a headline value, node ids, and a url — pass the url to `tako_contents` for rows (`exportable: true` cards) or a web result's full page text. When `exportable` is false the rows are locked — read the headline value from the card's `description`. Best for: breadth — fan out several narrow queries in parallel. Each query resolves one metric — for one entity, or a comparison set ("Apple revenue", "Nvidia vs AMD gross margin"); several metrics or topics in one query retrieve poorly. To learn what Tako covers, or a metric's canonical name, run `tako_available_data` first, then search on the canonical name it returns.
