Original Summary

Hey devs, While working on domestic payment flows, I found that most bank lookup solutions have noticeable network latency or lack direct UPI/ACH support indicators. To solve this, I built a fast Indian Financial data lookup service utilizing in-memory structures in FastAPI. Key features: - IFSC & Routing lookup: Checks UPI, ACH credit/debit, APBS, and NACH debit availability. - Card BIN routing: Maps first 6 digits to bank code and UPI rails. - Structure verification: Syntax and checksum validation for PAN entities and GSTINs. Tech Stack: - Python / FastAPI - In-memory execution for ~0ms latency - Hosted on Render cloud Live API Hub: [ India Banking, IFSC, PAN & GST Verification API ] Looking for technical feedback on the schema design and any edge cases in banking IFSC conventions.   submitted by   /u/Khemkaranpal [link]   [comments]
