How scoring works
Bands, evidence, coverage — and what we deliberately don’t claim.
API reference
Every endpoint, generated from the served OpenAPI contract.
Getting started
FIL Scoring API
Fraud risk scoring for phone numbers and IP addresses, backed by a consortium of telecom operators.
The FIL Scoring API answers one question: how risky is this phone number or IP address?
You send a subject, we return a 0–100 ranking against the scored population, a severity band, a recommended action, and the evidence behind all three. Evidence comes from fraud reports contributed by telecom operators (the consortium ledger) and from numbering-plan intelligence — which ranges exist, who operates them, and where fraud is accumulating.
Scores are rankings, never probabilities. A score of 78 means “riskier than 78% of scored ranges”, and every response says so.
