Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

minfraud

minfraud_factors

The most detailed assessment: everything in Insights PLUS risk_score_reasons and per-factor subscores explaining WHY the score is what it is. Same request body as minfraud_score. API: POST /minfraud/v2.0/factors.

minfraud_insights

Score a transaction AND get detailed risk insights: IP geolocation, email/address/device attributes, and per-component risk on top of the risk_score. Same request body as minfraud_score. API: POST /minfraud/v2.0/insights.

minfraud_report_transaction

WRITE — submits fraud feedback to MaxMind. Report the real-world outcome of a transaction (e.g. it was a chargeback or confirmed fraud) so minFraud can improve future scoring. This mutates MaxMind's model of your traffic; it is not a read. Requires a `tag` and at least one identifier (ip_address, maxmind_id, minfraud_id, or transaction_id). API: POST /minfraud/v2.0/transactions/report (returns HTTP 204).

minfraud_score

Score a transaction for fraud risk. Returns the overall risk_score (0.01–99), IP risk, disposition, and remaining query funds — the lightest, cheapest assessment. Send at least device.ip_address (plus email/billing/order for a better score). API: POST /minfraud/v2.0/score.
