Answer one specific, bounded question from FormulaSignal's covered pre-workout Record.
When to use: Use for a single natural-language question about a covered product: what it declares now, whether it changed, what it costs per serving, or which covered products meet one stated numeric condition.
What it cannot provide: It cannot list the database, export products, answer medical or suitability questions, or answer about a product FormulaSignal does not cover.
Limits: One question, at most 300 characters. Your plan has a daily limit on how many distinct products, Signals and ingredients you may read. Repeating a question about the same product costs nothing extra; reading many different products costs one each. Do not iterate through products, aliases, or date windows to assemble a copy of the Record: it is refused, scored, and can suspend the key.
FormulaSignal covers a defined, counted set of U.S. pre-workout products. Coverage is not the whole category, and a product being absent from coverage says nothing about that product. Every response carries a status. `supported` means the Record answered. `partial`, `stale`, `under_review`, `ambiguous` and `unsupported` are all real answers about the Record and none of them is a fact about the product: report them as what FormulaSignal holds, never as what is true of the product. Read `limitations` and repeat what applies. An observation date is when a source was read, not when a change was made, and an observation window is not an exact reformulation date. Nothing here is medical advice or a suitability judgement for any person.
