  ATTOM does not publish per-call list pricing on its public site. The developer
  platform offers a free 30-day trial via api.developer.attomdata.com/signup;
  production plans (annual API subscriptions, bulk-data licensing, and cloud
  delivery via Snowflake/Databricks) are negotiated with ATTOM sales. The
  entries below capture the publicly visible commercial surface so downstream
  tooling can detect "contact-sales" pricing without inventing dollar amounts.
