Geocode AI documentation

Two products on one key: Boundaries returns the polygon of any administrative area by name or point; Areas turns a description into a validated polygon.

The base URL is https://geo-coder-service.vercel.app/. Every call is an op with one name and one input, reachable as a REST route, as POST /v1/ops/<name>, as an MCP tool, as a CLI command and from the plugins. GET /v1 lists them all with their JSON Schemas.

For agents

Point a model at /llms.txt (an index) or /llms-full.txt (the full reference), or give it the OpenAPI 3.1 spec. All three are generated from the same registry as this site, so they never disagree.
