Tools

• openalex_analyze_trends ~1543 tokens
  Aggregate OpenAlex entities into groups and count them. Use for trend analysis (group works by publication_year), distribution analysis (group by oa_status, type, country), and comparative analysis (group by institution or topic). Combine with filters to scope the analysis. Returns up to 200 groups
• openalex_describe_fields ~518 tokens
  List valid field names for an OpenAlex entity type and context (filter, group_by, or select). Use proactively before constructing a filter or group_by to avoid invalid-field 400 errors. Pass `query` to rank the list by name similarity — useful when you have a partial or guessed field name. Ranking n

Note: `direction` follows OpenAlex's filter convention, which inverts the common English readi

  Search, filter, sort, or retrieve by ID. Covers all OpenAlex entity types (works, authors, sources, institutions, topics, keywords, publishers, funders). Pass `id` to retrieve a single entity. Otherwise, use `query` and/or `filters` for discovery. Filters take a record object; an unambiguous native
