@Service
public class VeriShieldService {
    private final RestClient client = RestClient.create();
    public boolean isAllowed(String email) {
        Map<String, Object> report = client.post()
            .uri("https://verishield-edge-api.p.rapidapi.com/v1/verify")
            .header("X-RapidAPI-Key", System.getenv("RAPIDAPI_KEY"))
            .body(Map.of("email", email))
            .retrieve()
            .body(Map.class);
        Map<String, Object> risk = (Map<String, Object>) report.get("fraud_risk");
        return !"BLOCK".equals(risk.get("recommendation"));
    }
}

What this protects against

Disposable and temporary inboxes, Gmail dot-trick and plus-alias multi-accounting, high-entropy bot usernames, and freshly registered fraud domains. The API returns a 0-100 fraud score with an ALLOW, CHALLENGE_2FA or BLOCK recommendation.
