Steps
Review the field reference page to identify which listing attributes, such as agency, category, or location, are returned by the API
Download the published OpenAPI YAML file to generate a typed client or validate request and response shapes
Map the fields you need, such as closing date, condition, or starting bid, into your own client-side query and filter logic
Combine the field reference with the api_key and format parameters from the basics guide when constructing requests
Submit feedback or field questions through the documented GitHub issues channel if a field's meaning is unclear
Known gotchas
The API does not expose server-side field filtering beyond the documented parameters; most filtering by field must be done client-side after retrieving results
The field reference and OpenAPI file are the authoritative source for field names, which can differ from what the public auction listing pages display
