Tool	Type	What it does
`minfraud_score`	read	Minfraud score Score a single transaction for fraud risk and get back the overall risk score (0.01–99), IP risk, a recommended disposition, and remaining query funds — the lightest, cheapest minFraud assessment.
`minfraud_insights`	read	Minfraud insights Score a transaction and get detailed risk insights alongside the score — IP geolocation plus email, address, and device attributes with per-component risk — for richer fraud investigation.
`minfraud_factors`	read	Minfraud factors Run the most detailed minFraud assessment, returning everything in Insights plus risk-score reasons and per-factor subscores that explain exactly why a transaction scored the way it did.
`minfraud_report_transaction`	write	Minfraud report transaction Report a transaction's real-world outcome (chargeback, confirmed fraud, spam or abuse, or cleared) back to MaxMind so minFraud learns from your traffic and sharpens future scoring.
