Measured tools (6)

• search_agents read-only

  Search the public agent registry by capability and protocol. Preview data only.

  Parameters:

  • protocol — string
  • capability — string — Capability identifier or substring

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• search_resources read-only

  Search 350 prepared structured resource profiles by category, keyword or declared source hostname without contacting external providers.

  Parameters:

  • q — string — Up to 8 whitespace-separated terms within 100 UTF-16 code units including outer whitespace; all terms must match literal case-insensitive substrings across public fields, declared publisher names or declared source hosts, in any order. Example: World Bank public, or worldbank.org public. Hostname matches include label-boundary subdomains; no full URLs, credentials, control characters, stemming or model inference. Ordering: exact resource ID first, then every term matched as a whole word in the title or a declared publisher name, or as a declared source host, then remaining substring matches; ties use stable resource ID order. Ranking is not a quality or ownership assertion.
  • limit — integer
  • cursor — integer
  • category — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_resource read-only

  Retrieve one complete prepared resource profile, including evidence-backed facts and primary-source provenance, by its stable resource ID.

  Parameters:

  • resourceId (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_niulai_info read-only

  Return publisher-declared Base network, contract, claim, community-role, custody, and risk-boundary information for 牛来 (NIULAI).

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_growth_metrics read-only

  Return enabled, partial, contract-only, and unavailable growth metrics with privacy and interpretation boundaries.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• compile_query_plan read-only

  Normalize a public-data query into a typed evidence, freshness, latency, result, and cost plan. Compilation does not execute retrieval or contact providers.

  Parameters:

  • intent (required) — string
  • limits — object
  • output — object
  • policy — object
  • sources — array
  • evidence — object
  • freshness — object

  Hints: read-only yes · destructive no · idempotent yes · open-world no
