How an AI agent should use this page

Ground rule: Navigate with HTML GET links to keep explanations and relationships. Use the page's JSON alternative only when concrete values must be extracted, compared or computed.

How to use the get_group_structure lookup

Replace the placeholders in the HTML GET template; remove optional parameters you do not need.
Check types, units, limits and ID formats in the parameter table.
Follow linked results to canonical pages before combining sources.

Misreading to avoid: An empty list means "no results for this lookup". An error message or unavailable source does not mean the data does not exist.

Source-specific next step

Confirm the organization number before detail lookups. Use the canonical company page to combine owners, roles, grants, Doffin and jobs.

Go to the source page for other operations. Use the JSON template only after the HTML result shows that the parameters and source are correct.
