Save to a collection (free)

Save a statistic page to one of the user's collections when they ask to keep, bookmark or save it. Without collection it goes to the default collection, "Saved". Saving the same page again keeps one item and updates its note. What to save: an indicator and a place (a value), an indicator and a ranking scope (a ranking, scope as in the ranking URL: "us-states", "eu-countries", "countries", "texas-counties"), an indicator alone, a place alone, a topic or a publisher. kind is inferred when left out. Examples: {"indicator": "unemployment_rate", "place": "Texas"}. {"indicator": "gdp_per_capita_usd", "scope": "countries", "note": "For the board deck"}. {"kind": "topic", "topic": "labour", "collection": "col_3f9a..."}. Returns {collection: {id, name, visibility}, item: {id, kind, note?}, created, dashboard_url}. A collection holds up to 100 items. Free on every plan.
