Geocode AI

What you can ask

• Get the boundary of Alameda County as GeoJSON.Copy

  Example path get_boundary

• Which city and county is 37.8, -122.27 in?
• Make one polygon for the Bay Area counties, excluding San Francisco.

Instructions

Geocode AI. Boundaries and areas API for every place on Earth. Administrative boundaries come from OpenStreetMap and are cached, so repeat lookups are instant.

Workflow:

A named place (country, state, county, city, district, postcode): search_boundaries with the name (add the country or parent to disambiguate), pick the result whose admin level and parents match, then get_boundary with its id for the polygon. Never guess an id.

A coordinate: reverse_boundaries returns every boundary containing it, country down to neighbourhood.

Everything inside a boundary (states of a country, counties of a state): list_children with the parent's id.

Which zone each of many points falls in: contains_points (one batch, not one call per point).

Several boundaries as one shape: union_boundaries with their ids.

A described area that is not one named place ("the Bay Area minus San Francisco", a service area clause from a contract): create_area with the text. It runs an AI agent for 30 s to a few minutes and costs 50 units, so use it only when search + get cannot answer.

• Geocode APIWrite code that calls the Geocode AI API - REST (fetch, curl, Python requests) with the OpenAPI spec, the @meterapp/geocode CLI in scripts and CI, or the hosted MCP server from an agent framework.
• Geocode AreasTurn a plain-language description of an area into one validated polygon with Geocode AI's create_area - "Alameda and Contra Costa counties excluding Oakland", "the Bay Area minus San Francisco, plus SFO", a delivery or service area, or wording pasted from a contract, policy, license or regulation.
• Geocode BoundariesLook up administrative boundaries anywhere in the world with Geocode AI and work with their polygons - find a country, state, county, city, district or postcode by name, get its polygon as GeoJSON, find every boundary containing a coordinate (reverse), list what is inside a boundary (children), check which zone each of many points falls in (contains), and merge several boundaries into one shape (union).
• Geocode FeedbackReport a Geocode AI bug with the failing request attached, request a missing feature, upvote or comment on what others asked for, follow up on what the human filed, and post or read reviews - report_issue (with the request_id from the failed call), request_feature, upvote_feedback, comment_on_feedback, list_feedback, get_feedback, list_my_feedback, submit_review, list_reviews.
• Geocode TeamsWork inside a Geocode AI organization - tell which organization a key or connection acts in and the caller's role (get_account, list_orgs), who is in it and which teams exist (list_members, list_teams), save a boundary export to the organization's shared file library (save_file), find files teammates saved (list_files, get_file) and share a file with a team or a person at read, write or admin access (share_file, unshare_file, update_file).
