# Close

> Close (close.city) is an interactive travel-time map of the United States. It
> shows, block by block, how long it takes to walk, bike, or take public transit
> to the amenities you choose. Built by Henry Spatial Analysis, LLC (Seattle).

Most close.city pages are a JavaScript application and render no content without
a browser, so this file carries the key facts inline. The developer surfaces
linked below (docs site, OpenAPI spec, MCP server) serve full content to any
client.

## What Close does

- Pick destination types (grocery stores, schools, parks, transit stops, and
  more); the map colors each block by the combined travel time to the furthest
  of your selected amenities.
- Set the travel mode per destination: walking, biking, or walking plus public
  transit.
- The free map shows up to 6 destination types at once, with no account needed.
  The free map stays free.
- Coverage: cities and counties across the United States, computed at
  census-block level.

## Close API (for developers and AI agents)

The Close API serves the same travel-time data programmatically. New accounts
get 5,000 free API tokens with no card required. An AI agent can complete
sign-up on a user's behalf over JSON; the user confirms by reading a six-digit
code from their own email inbox.

- [API documentation](https://docs.close.city): guides and full API reference.
- [For AI agents](https://docs.close.city/ai/): compact reference including the
  programmatic sign-up transcript.
- [Docs as plain text](https://docs.close.city/llms.txt): also
  [llms-full.txt](https://docs.close.city/llms-full.txt).
- [OpenAPI 3.1 spec](https://api.close.city/openapi.json): served live by the
  API.
- MCP server at https://mcp.close.city/mcp, published in the official MCP
  registry as city.close/close-api. Its tools include the sign-up pair that
  mints a free API key in-chat.

## Policies

The policy pages (close.city/billing, close.city/terms, close.city/privacy)
require JavaScript in a browser. In brief: Close+ renews monthly until
canceled; cancel at https://account.close.city/ or by emailing
support@close.city; the 30-day first-payment refund above is the full refund
policy.
