Rio de Janeiro Open Data Catalogue: Datasets, Descriptions and Licences (Data.Rio)

datario/list-datasets

A page of the Data.Rio open data catalogue of the city of Rio de Janeiro: for each dataset its title, description, owner, source, licence, tags, categories and dates. Choose how many datasets to return (1 to 20) and, to move through the catalogue, the 1-based position to start from. The response also reports how many datasets match in total. Only CC-BY-4.0 datasets are returned (others are filtered out); read license and accessInformation on each item and credit its source. Descriptions are HTML and mostly in Portuguese. Data.Rio catalogue metadata, passed through unmodified and served by Eden Engine; not an official Prefeitura da Cidade do Rio de Janeiro product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "datario/list-datasets" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "datario/list-datasets" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "datario/list-datasets", input: { /* see input_schema */ }, dry_run: true })
