Step 1 Financial fraud detection using card, telecom, and public data coalition

Step 2 Building a public data coalition fraud detection system
→
Step 3 Public data API integration development tools

Problem

Fintech and security Startups (3-10 developers) building financial fraud detection systems need to integrate card, telecom, and public data APIs (from agencies like the Ministry of the Interior and the Financial Supervisory Service), but each API has different authentication methods, response formats, and rate limits — averaging 2-3 days per API integration. Integrating 5-6 public APIs wastes 2-3 weeks on initial development alone, and API schema changes require an additional 3-5 days of debugging.

Solution

(1) Wrap 30+ public data APIs useful for financial fraud detection into a single standardized interface, (2) auto-handle authentication, rate limiting, and error handling, (3) provide automatic schema change detection and backward-compatible adapters. Integration in 3 lines of code via Python/Node SDK.
