Tools as reported by the server

• find_api_for_task
  Find the best APIs for a natural-language physical-world task. Use this for open-ended task or outcome-based recommendations; use search_apis when you already know exact filters, get_api for one known API, or compare_apis for known candidates. Returns an authoritative canonical structured_results sh
• search_apis
  Search the canonical registry when you already know keywords or exact requirements. All supplied filter groups combine with AND logic; array capability filters require every supplied value, and protocol fields match the exact Yes/No/Unknown status, so Unknown never satisfies Yes. Results include eac
• search_capabilities
  Search the canonical 770-capability Verified/High decision graph directly. Use this when the question is about what an agent can actually do and under what execution conditions: task/capability text, API, category, action type, acted-on object, human approval, physical consequence, irreversibility,
• verify_requirement
  Verify whether one specific API can satisfy one exact requirement using the canonical Verified/High capability graph plus linked assertion evidence. Returns YES, NO, PARTIAL or UNKNOWN with matched capability, access/setup prerequisites, approval, safety, reversibility, reliability, coverage and oth
• get_api
  Retrieve one canonical API decision profile when you already know its name or slug. The response includes the full Verified/High capability profile with execution, access, approval, reversibility, physical-consequence and evidence fields. Exact slug or exact API name is preferred; a partial identifi
• compare_apis
  Compare 2–8 already-known APIs side by side using canonical catalog fields plus capability-graph summary fields such as verified capability count, physical consequences, approval relevance and irreversibility. Use get_api for the full decision profile of one API and search_capabilities for capabilit
