Tools
| Name | Description | Input keys |
|---|---|---|
| get_firm | One prop trading firm. Every figure states whether we hold evidence for it, and a firm whose score range spans more than one band carries no letter grade at all. | slug |
| get_rule_changes | The dated record of what changed, newest first. Every entry states its KIND, and most of this tape is FirmFax correcting its own data rather than a firm changing its rules. Read counts before describing industry activity: a total taken across kinds overstates it. | kind, limit, since, slug |
| get_evidence | The stored reading behind a figure: the verbatim quote, the page it came from, and the date we read it. Answers "we hold none" explicitly rather than returning an empty list. `outcome` is load-bearing: a `contradicted`, `contradiction` or `absent` row records what we read, not a figure we publish. U | field, slug |
| find_firms | Firms matching every criterion given. A firm whose record does not carry a criterion is never counted as a match and never silently dropped: it is returned separately under unknown, with the field that could not be tested. Absence is common here, so read counts before treating the matched list as th | assetClass, dailyLossLimitUnit, maxActivationFee, maxConsistencyPct, maxDailyLossLimit, maxMinDaysToPayout, maxMinTradingDays, maxResetFee, minDaysToPayoutMinProfit, minDaysToPayoutUnit, minTradingDaysMinProfit, minTradingDaysUnit |
| compare_firms | Two firms side by side. Reports each figure with its evidence state and whether the pair is comparable at all: a field neither firm records is not a tie, and a field only one records is not a win. No per-field winner is declared, because the direction of "better" for several of these is a judgement | a, b |
| list_firms | Every firm slug and name. Carries no figures, so nothing here needs evidence. |
