Tools of Close API
	Description		Read-only	Idempotent	Open world
`blocks_in_area`Per-block travel times for every census block in an area (metered: 1 token per returned row). Give place_geoid (from find_place) for a whole city, or center {lat, lon} + radius_m. Rows carry a numeric mode_id.	Per-block travel times for every census block in an area (metered: 1 token per returned row).

`find_place`Look up a US city or town by name (free, no key). Returns matches with their census place GEOID and centre point (lon/lat). The entry point: feed a GEOID to blocks_in_area, or a centre to walkability_summary.	Look up a US city or town by name (free, no key).

`get_catalog`List the travel modes and the destination-type taxonomy (free, no key). Use it to resolve type names to the numeric ids the other tools take.

`isochrone`The area reachable from a location within a time budget, as GeoJSON contours (metered: 10 tokens per contour). Give block_geoid or lat+lon. Defaults to a single 30-minute contour; ask for more only when needed (bodies can be large).

`join_close_plus`Get a Stripe Checkout URL for the Close+ membership ($10/month: 5,000 API tokens granted monthly plus member features on the close.city map). The user pays in their own browser: give them the returned URL and stop. Needs a fresh six-digit code from request_sign_in, read by the user from their own inbox.

`nearby_pois`Nearby points of interest and the travel time to each, from a location (metered: 1 token per returned row). One origin: block_geoid or lat+lon; keep limit small to control spend and context size. Many origins (up to 250): block_geoids or points — one batch call and one rate-limit request, rows tagged by origin, no limit/pagination, so filter with type/mode/max_minutes. Batching saves requests and context, not tokens: it still charges per row. A non-empty truncated (+ truncated_reason) means the balance or row budget cut the batch short.

`redeem_code`Complete sign-up with the six-digit code the user received, and return a new API key (shown once). Call request_sign_in first.
