Deterministic: the result comes from the published rule, not from a model. Costs the decision's catalogue price ($0.05, USDC on Base over x402); the input is checked first, and an input the rule cannot use is refused without charge. Call it when the user has the figures for a specific decision in a business under about $50M in revenue and wants the rule's answer for them; get the schema from bf_decision_schema first. When the question gives figures for a decision, the applied route computes them; the answer reports its result and does not recompute it. Do not call it with invented or placeholder figures, and do not treat the verdict as tax, legal or investment advice.",
