• sparql_askExecute SPARQL ASK Queryread-only

  Execute a SPARQL ASK query and return a boolean result. ASK queries test whether a pattern exists in the data, returning true or false. Args: params: Query parameters including endpoint URL, SPARQL ASK query, timeout, and optional headers. Returns: "true" if the pattern exists, "false" otherwise. Examples: >>> # Check if a specific item exists >>> sparql_ask(SparqlAskInput( ... endpoint="https://query.wikidata.org/sparql", ... query="ASK { wd:Q42 wdt:P31 wd:Q5 }" ... )) "true" >>> # Check if a relationship exists >>> sparql_ask(Sparq…

• sparql_constructExecute SPARQL CONSTRUCT Queryread-only

  Execute a SPARQL CONSTRUCT query and return RDF triples. CONSTRUCT queries build an RDF graph from a template pattern. Results are returned as Turtle RDF or JSON-LD. For large-scale graph construction, increase the timeout parameter — default is 30s, maximum is 3600s (1 hour). Args: params: Query parameters including endpoint URL, SPARQL CONSTRUCT query, timeout, output format, optional headers, and max rows limit. Returns: RDF triples formatted as Turtle or JSON. Examples: >>> # Construct a subgraph >>> sparql_construct(SparqlConstructInput( ... endpoint="h…

• sparql_describeExecute SPARQL DESCRIBE Queryread-only

  Execute a SPARQL DESCRIBE query and return an RDF resource description. DESCRIBE queries return an RDF graph describing the specified resource(s). For resources with many properties, increase the timeout parameter — default is 30s, maximum is 3600s (1 hour). Args: params: Query parameters including endpoint URL, SPARQL DESCRIBE query, timeout, output format, optional headers, and max rows limit. Returns: RDF description formatted as Turtle or JSON. Examples: >>> # Describe a Wikidata entity >>> sparql_describe(SparqlDescribeInput( ... endpoint="https://query…

• sparql_get_prefixesGet SPARQL Prefixesread-only

  Get commonly used prefixes for a SPARQL endpoint. Returns a combination of well-known standard prefixes (rdf, rdfs, owl, xsd, etc.) and any endpoint-specific prefixes discovered via the data. Args: params: Parameters including endpoint URL, timeout, and optional headers. Returns: Formatted list of prefix declarations for use in SPARQL queries. Examples: >>> sparql_get_prefixes(SparqlGetPrefixesInput( ... endpoint="https://query.wikidata.org/sparql" ... )) "PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>\n..."

• sparql_list_graphsList Named Graphsread-only

  List available named graphs on a SPARQL endpoint. Queries the endpoint for all named graphs (contexts) available for querying. Args: params: Parameters including endpoint URL, timeout, and optional headers. Returns: List of named graph URIs. Examples: >>> sparql_list_graphs(SparqlListGraphsInput( ... endpoint="https://query.wikidata.org/sparql" ... )) "Found 3 named graphs:\n1. http://example.org/graph1\n..."

• sparql_queryExecute SPARQL SELECT Queryread-only

  Execute a SPARQL SELECT query against a SPARQL endpoint. Runs a SELECT query and returns results as a Markdown table or JSON array. Supports custom HTTP headers for authenticated endpoints. For long-running queries (large datasets, complex joins), increase the timeout parameter — default is 30s, maximum is 3600s (1 hour). Args: params: Query parameters including endpoint URL, SPARQL query, timeout, output format, optional headers, and max rows limit. Returns: Query results formatted as a Markdown table or JSON string. Examples: …

• sparql_validateValidate SPARQL Query Syntaxread-only

  Validate SPARQL query syntax without executing it. Parses the query and reports whether it is syntactically valid. Useful for debugging query errors before running them against an endpoint. Args: params: Validation parameters containing the SPARQL query string. Returns: Validation result with status and error details if invalid. Examples: >>> # Valid query >>> sparql_validate(SparqlValidateInput(query="SELECT ?s WHERE { ?s ?p ?o }")) "Valid SPARQL query." >>> # Invalid query >>> sparql_validate(SparqlValidateInput(query="SELECT WHERE { }")) "Invalid SPARQL …
