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
Returns a JSON object with: 'valid' (boolean indicating format correctness), 'scope' (whether check is checksum or format-only), 'reason' (human-readable explanation of result), 'entity_type' (individual, company, etc. as encoded in PAN), 'entity_code' (the encoded character), 'normalized' (cleaned PAN string), and 'tool' (identifier of the check performed). Response is deterministic and offline — no external database lookup is performed.
Example use cases
KYC pre-flight PAN check
“Before we submit this customer's KYC form, can you validate whether the PAN 'AAAPA1234C' is correctly formatted and tell me the entity type it encodes?”
Batch onboarding vendor PAN validation
“We received a vendor PAN of 'BBBPB5678G' — can you run a quick offline format check to confirm it's valid and what kind of entity it represents before we add them to our payment system?”
Tax form pre-submission check
“I'm about to file a tax form and I want to make sure the PAN 'CCCPC9012H' I've entered is correctly structured — can you validate its format and tell me whether it's an individual or company PAN?”

Endpoint
POSThttps://hcrb.in/v1/tools/pan-format-check/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, privacy-preserving offline check of Indian PAN numbers without sending data to a third-party registry or KYC service. Ideal for pre-flight validation before expensive KYC pipelines, bulk onboarding deduplication, or any workflow where deterministic format correctness (not live registry lookup) is sufficient. At $0.005 USDC per call with 3 free calls/day, it is cost-effective for low-to-medium volume checks. Prefer over ML-based or scraping-based validators when auditability and determinism matter.
Side effects
- Invalid or malformed PAN input returns valid:false with a reason string
- Missing required PAN field in request body returns an error
- Payment not attached or insufficient USDC balance causes 402 Payment Required response
- Non-PAN identifiers passed to this endpoint return format mismatch errors
- Rate limiting beyond free tier without payment fails with 402
