Measured tools (6)

• search_meetings read-only

  Search Narcotics Anonymous meetings on a BMLT root server. Filter by location (address or lat/lng + radius), weekday, time of day, format, venue type (in-person / virtual / hybrid), and service body. Returns a trimmed summary by default; pass data_format='full' for the raw BMLT response.

  Parameters:

  • page — integer — Page number (1-indexed). Used with page_size.
  • address — string — Free-form address to search near (geocoded server-side). Ignored if latitude+longitude are provided.
  • language — string — Language code for format names (e.g. "en", "es", "de", "fr").
  • latitude — number — Latitude in decimal degrees. Pair with longitude for an exact-coordinate search.
  • weekdays — array — Weekday filter. 1=Sunday, 2=Monday, ..., 7=Saturday. Example: [2,4,6] for Mon/Wed/Fri.
  • longitude — number — Longitude in decimal degrees. Pair with latitude for an exact-coordinate search.
  • page_size — integer — Results per page. Omit to return all matches.
  • radius_km — number — Search radius in kilometers. Takes precedence over radius_miles when both are provided. Ignored when no coordinates are provided.
  • format_ids — array — BMLT format IDs to require. Use list_formats to discover IDs (e.g. Open, Closed, Speaker, Beginners).
  • data_format — string — "summary" returns a curated subset of fields (default). "full" returns the raw BMLT response.
  • search_text — string — Free-text search across meeting name, location, and notes.
  • venue_types — array — Venue type filter. 1=In-person, 2=Virtual, 3=Hybrid.
  • radius_miles — number — Search radius in miles. Defaults to 10. Ignored if radius_km is provided or no coordinates are given.
  • starts_after — string — Earliest start time as 24h "HH:MM" (e.g. "18:00").
  • starts_before — string — Latest start time as 24h "HH:MM" (e.g. "21:30").
  • root_server_url — string — Override the configured BMLT root server URL. Must be allowlisted unless BMLT_ALLOW_ANY_ROOT=true.
  • service_body_ids — array — Restrict to specific service bodies (regions/areas). Use list_service_bodies to discover IDs.
  • recursive_services — boolean — When service_body_ids is set, also include their children. Default true.
