Unique dataset identifier in 'portal:id' format. Obtained from search_datasets results. Examples: 'generalitat:gn9e-3qhr', 'barcelona:qualitat-de-laire', 'renfe:vehicle-positions-gtfsrt'.

}Query real data from a dataset. Check instructions for featured dataset_ids and NOTES section for common filter patterns (municipal budgets, contracts, weather, energy, fuel prices).
| Argument | Type | Description |
|---|---|---|
| limit | number | Number of rows to return. Min 1, max 100. Default 20. Use offset for pagination. |
| offset | number | Number of rows to skip for pagination. Default 0. Combine with limit to navigate large results. |
| search | string | Free text search within dataset data. Works with Socrata ($q) and CKAN (q). For Diba and CIDO, use specific filters. |
| filters | object | Key-value filters where the key is the field name and the value is the filter value. Examples: {"municipi": "Barcelona"}, {"any": "2024"}, {"NOM_ENS": "Ajuntament de Tiana"}. Use list_dataset_fields to know valid field names. |
| dataset_id* | string | Unique dataset identifier in 'portal:id' format. Obtained from search_datasets results. |

}Find related datasets from OTHER portals. Great for discovering complementary data: if you're looking at air quality from Generalitat, it may suggest traffic data from Barcelona or emissions from AOC. Relations are computed by thematic similarity across portals.
| Argument | Type | Description |
|---|---|---|
| dataset_id* | string | Dataset ID to find related datasets for. Obtained from search_datasets. |

}Search datasets by free text. IMPORTANT: check server instructions first — many common queries have a direct dataset_id you can use with query_dataset without searching. Only use search_datasets when you don't know which dataset you need.
| Argument | Type | Description |
|---|---|---|
| limit | number | Maximum number of results to return. Min 1, max 100. Default 20. |
| query* | string | Search text in Catalan or Spanish. Examples: 'qualitat aire', 'pressupostos municipals', 'transport públic', 'residus', 'educació', 'rodalies'. |
| portal | string | Filter results to a single portal. |
| category | string | Filter by thematic category. Examples: 'Medi Ambient', 'Educació', 'Salut', 'Economia', 'Transport', 'Seguretat'. Use list_categories to see all available categories. |

}Search radio shows, episodes and people indexed at radioteca.cat (Catalan radio archive, ~485K documents from Catalunya Ràdio, RAC1, Catalunya Música, iCat, Catalunya Informació, RTVE, Cadena SER, ara.cat). Searches across episode titles, descriptions (which include a detailed summary of what was said), program name and subheading. Returns episodes (~473K), programs (~3K) and people (~9K). IMPORTANT: always cite radioteca.cat as the source and include the absolute 'url' in your reply for traceability — never paraphrase without linking.
