Compare observed nightly lodging rates for one city across the check-in months that were collected, for a single stay length and occupancy. Returns each month's distribution, the like-for-like subset of properties present in every month, and a cheapest month stated only from that subset. Each month is one sampled check-in date, not a monthly average. A priced call is settled only when the response contains observations; a no-data answer (`no_data_reason` set) is returned unbilled, marked by the `X-BUDGETATLAS-BILLED` response header.
Call get_dataset_coverage first. It is free and lists the cities and cohorts that exist.
An answer with no data (no_data_reason set) is not settled upstream. OpenTools bills zero for it.

Use this exact tool
Every snippet below names budgetatlas/v1/compare_lodging_months, so an agent runs this endpoint instead of searching for something similar.
Use the OpenTools tool budgetatlas/v1/compare_lodging_months (https://opentools.fulinlabs.com/tools/budgetatlas/v1/compare_lodging_months?method=POST). Connect to the OpenTools MCP server at https://opentools.fulinlabs.com/mcp (or install the CLI with `npm i -g @aeither/opentools`). Do not search the catalog — call `inspect` with provider "budgetatlas" and endpoint "/v1/compare_lodging_months" and method "POST" for the input schema, then `run` with the same provider and endpoint.
