Deterministic validation of Indian Permanent Account Number (PAN) issued by CBDT / Income Tax Department with 4th-character entity type classification (Individual, Company, Firm, Trust, HUF).

Honest Scope Guarantee

Format-only: Indian PAN structure and 4th-character entity-type classification (Individual/Company/Firm/Trust etc.) validated deterministically. NOT a CBDT/Income Tax Department registration lookup, and no PAN-vs-name matching is performed.

No API key needed for the free daily tier. When daily quota exhausts, the endpoint replies with HTTP 402 Payment Required specifying the exact USDC amount. Machines sign an EIP-3009 transfer on Base L2; human engineers buy card credits. Every paid execution returns a cryptographically signed XDR-1 receipt for zero-knowledge audit trails.
