Free. What a call to a SalesMap tool is expected to cost, before running it, against what the workspace can spend now (credits and limits); and whether it runs as a job (rank over 10+ companies, verify over 25+ rows). Not a charge: the most the call can charge, which it reserves (or its max_usd); it is charged per result returned (rank: its model cost), never more.
Use when: before a batch, "how much will this cost", "can I afford to rank these 20 accounts", "what would discover cost".
Skip when: the user wants their balance or limits without a call in mind. Quoted page text is normalized; a quote that reads like an instruction keeps its text and is flagged in Flags with the attack family.
