Fraud Detection & Risk Scoring in Swift

Returns a score (0–100) and a human riskLevel, plus the factors that drove it. Use riskScore() for the caller's IP.

let client = IpApiClient(apiKey: ProcessInfo.processInfo.environment["IP_API_IO_KEY"]!)

let risk = try await client.riskScore(ip: "185.220.101.1")

print(risk.score)     // 88.0
print(risk.riskLevel) // "high"
if let ip = risk.factors.ip {
    print(ip.isTorNode, ip.isDatacenter)
}

if risk.score >= 75 {
    // block, or send to manual review / step-up auth
}

Same 0–100 scale, driven by email signals (disposable provider, invalid syntax). Use it to grade leads or gate sign-ups by address quality.

let risk = try await client.emailRiskScore(email: "user@mailinator.com")

print(risk.score, risk.riskLevel) // 90.0 high
if let email = risk.factors.email {
    print(email.isDisposable) // true
}

Returns the underlying reputation data for an IP — use it when you want the source signals rather than a computed score.

let reputation = try await client.ipReputation(ip: "185.220.101.1")
print(reputation)
