Measured tools (14)

• search_public_datasets read-only

  Use this free tool first when an agent needs official US federal data but does not yet know the dataset ID. Searches normalized catalog metadata and returns matching datasets with provenance; it does not query dataset rows.

  Parameters:

  • query (required) — string — Plain-language topic, agency, or dataset keywords, such as employment, schools, or air quality.

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

• request_dataset_materialization

  Queue a discovered official dataset for prioritized detached ingestion. This free idempotent operation returns a durable job ID; poll get_materialization_status until it supplies sample and query URLs.

  Parameters:

  • discovered_dataset_id (required) — string — Exact catalog ID returned by search_discovered_datasets.

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

• get_materialization_status read-only

  Poll a durable materialization job. A complete result includes the query-ready dataset ID plus free sample and paid query URLs.

  Parameters:

  • materialization_id (required) — string

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

• list_official_sources read-only

  Use this free tool to inspect which federal, state, city, police, education, and other official source scopes AgentNative currently covers. Returns each source's importer, discovery state, and materialized coverage; it does not return dataset rows.

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

• search_discovered_datasets read-only

  Use this free tool to find datasets across all discovered official sources, including candidates not yet queryable. Returns catalog matches and materialization state; use list_imported_datasets when only query-ready data is acceptable.

  Parameters:

  • limit — integer — Maximum matches to return; defaults to the service limit.
  • query — string — Optional title or description keywords.
  • source_id — string — Optional exact official source ID returned by list_official_sources.

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

• get_coverage_status read-only

  Use this free operational tool to decide whether available public-data coverage is sufficient or whether to request a missing capability. Returns discovery, materialization, queryable-row, queue, failure, and freshness counts.

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

• list_imported_datasets read-only

  Use this free tool when an agent needs only datasets that can be sampled or queried now. Returns fully published warehouse snapshots with dataset IDs, row counts, freshness, and provenance.

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

• sample_imported_dataset read-only

  Use this free tool to evaluate a query-ready official dataset before paying. Returns three normalized rows, deterministic summaries, freshness, and provenance; use query_imported_dataset only after the sample proves useful.

  Parameters:

  • dataset_id (required) — string — Exact query-ready dataset ID returned by list_imported_datasets.

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

• sample_us_federal_register read-only

  Use this free no-auth tool for current US regulatory activity or to evaluate AgentNative before paying. Returns three Federal Register records plus deterministic aggregates over the latest 25 documents, direct record URLs, provenance, and rate-limit status.

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

• query_imported_dataset read-only

  Use this paid read-only tool after sample_imported_dataset confirms the data is suitable. Returns up to 100 normalized rows from a published snapshot with bounded pagination, one exact-match filter, freshness, and provenance.

  Parameters:

  • dataset_id (required) — string
  • top — integer
  • skip — integer
  • filter_field — string
  • filter_value — string

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

• aggregate_imported_dataset read-only

  Use this paid read-only tool for deterministic grouped statistics instead of downloading rows and calculating locally. Returns bounded count, sum, average, minimum, or maximum groups with dataset provenance.

  Parameters:

  • dataset_id (required) — string
  • group_by (required) — string
  • top — integer
  • field — string
  • metric

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

• request_capability

  Use this state-changing tool only when existing discovery and coverage tools cannot satisfy the task. Records demand for a missing dataset, aggregation, insight, filter, freshness level, or export; repeated requests increase autonomous build priority.

  Parameters:

  • dataset (required) — string
  • capability (required) — string
  • source_url — string
  • example_query — string

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

• request_paid_access

  Use this state-changing tool only after free samples demonstrate value and the human owner approves payment. Creates a Stripe Checkout plus one-time claim URL; choose the $5 pass for research or $5/month subscription for recurring workflows.

  Parameters:

  • plan — string

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

• query_us_federal_register read-only

  Use this paid read-only tool when the free Federal Register briefing is insufficient. Returns up to 100 normalized official records filtered by date or document type, with deterministic provenance and direct source URLs.

  Parameters:

  • top — integer
  • type — string
  • end_date — string
  • start_date — string

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