How this service works
Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.
Output
A JSON object with a boolean 'valid' field, a 'reason' string explaining the result, a 'scope' field indicating whether the check was checksum-verifiable or format-only, a 'normalized' form of the code, and a 'country' field. For IFSC, scope will indicate format-only since IFSC does not have a public checksum algorithm.
Example use cases
Pre-transfer bank routing validation
“Before I send this wire to the Indian bank account, can you verify that the IFSC code HDFC0001234 is valid and correctly formatted?”
Bulk payment file sanity check
“I have an IFSC code ICIC0000001 from a vendor invoice — can you confirm it's a legitimate format before I add it to our payment system?”
KYC onboarding data validation
“We're onboarding a new supplier and they gave us the IFSC PUNB0244200 — can you run a format check on it so we know it's not a typo before we save it to our records?”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/ifsc-check/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, offline, deterministic format check on an IFSC code with no dependency on external bank registries or ML models. It is ideal for pre-validation in payment pipelines, KYC flows, or data entry sanitization where you want a sub-cent, privacy-preserving check without sending data to a third-party registry.
Side effects
- Malformed or empty input returns valid:false with a descriptive reason
- IFSC codes that pass format but belong to non-existent branches cannot be detected (offline check only)
- Payment failure via x402 if USDC balance is insufficient (after 3 free daily calls)
- Network timeout if the endpoint is temporarily unreachable
