Ask with this source

A prompt for your agent that names this source and how to call it through the crw MCP.

  • Pages linking to an entity

    Use Wikidata (wikidata) from fastCRW Pergamon, capability "Pages linking to an entity" (backlinks). You want the reverse direction - which items point AT this one - without writing a SPARQL query. Example options: bltitle=Q42, bllimit=100, blnamespace=0. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "wikidata" and capability "backlinks". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Entity statements

    Use Wikidata (wikidata) from fastCRW Pergamon, capability "Entity statements" (claims). You want one entity's facts and nothing else, or you want a single property's values rather than the whole record. Example options: entity=Q42, property=P569, rank=normal. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "wikidata" and capability "claims". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Constraint violations for an entity

    Use Wikidata (wikidata) from fastCRW Pergamon, capability "Constraint violations for an entity" (constraint-check). You want to judge how trustworthy or well-formed an item's data is before you rely on it. Example options: id=Q42, status=violation. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "wikidata" and capability "constraint-check". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Supported term languages

    Use Wikidata (wikidata) from fastCRW Pergamon, capability "Supported term languages" (content-languages). You need to validate or offer a language code before using it as a languages or language_code argument elsewhere. Example options: wbclprop=code|autonym|name, uselang=fr. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "wikidata" and capability "content-languages". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
