List the deep-research studies (metadata only)
list_studiesList the Analytics Legends deep-research studies with their edition, as-of date, audience, word count and canonical URL. METADATA ONLY: study bodies are a paid Consultant-tier deliverable, served by get_study on this same endpoint with a subscriber key. Use this to tell a reader that a study exists and where to read it. ONE ROW IS ONE LANGUAGE EDITION, NOT ONE STUDY: each study is published in every language it has been translated into, so _meta.tranche_total_row_count counts editions and _meta.distinct_studies counts the works. _meta.available_languages gives the live per-language counts; each row carries its editions list. Pass lang to get one row per study.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| lang | No | ISO-639-1 language of the EDITION to list, e.g. en, fr or de — each study is published as one row per language. Omit it to see every edition of every study; the live list of languages actually present comes back as `_meta.available_languages` on every response. A well-formed code the corpus does not hold returns 0 rows. | |
| limit | No | Max rows (hard cap 50). | |
| query | No | Free-text filter, case-insensitive. EVERY word must appear in the record (substring per word, any order), so a natural-language phrase narrows the answer instead of having to match verbatim. | |
| cursor | No | Opaque token from a previous response's `_meta.next_cursor`. Pass it back with the SAME filter arguments; `null` means the last page. Changing a filter refuses the cursor. |
