How this service works
Estimate evidence-supported probability and expected loss for decision support
Output
Returns an evidence-supported risk probability (likelihood of loss or fraud) and an expected loss figure for the transaction, designed to inform accept/reject decisions with traceable reasoning.
Example use cases
Pre-approval fraud screening for payments
“We're about to send a $15,000 ACH payment to a vendor we've never paid before — can you run a transaction risk score on it to get the probability of loss and expected exposure before we approve?”
E-commerce order risk triage
“A customer just placed a $3,800 order using a shipping address that doesn't match their billing address — can you estimate the fraud probability and expected loss so I know whether to hold the order for review?”
Automated lending disbursement gate
“Before disbursing this $9,500 loan to a borrower, run a transaction risk assessment and tell me the evidence-backed probability of default and expected loss amount so we can decide whether to proceed.”

Endpoint
POSThttps://phion.systems/v1/paid/trust/transaction-risk-score?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an evidence-backed, quantified risk score (probability + expected loss) for a specific transaction before processing or approving it, especially in automated payment pipelines, lending workflows, or fraud triage systems where a numeric risk output with supporting evidence is required for downstream decisioning.
Side effects
- Insufficient transaction data provided returns a validation error or low-confidence score
- Malformed or missing required fields result in schema rejection
- Ambiguous counterparty identifiers may produce low-confidence estimates
- Service unavailability returns a 402 or 5xx error
- Transactions with no historical signal may yield inconclusive probability estimates
