$0.005 / callPaid per call · 0 free tier No signup

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.

Quickstart & Execution

cURL (Paid-only route — unauthenticated calls return HTTP 402 Payment Required)

curl -X POST https://api.code402.dev/v1/tools/pan-format-check/call \
  -H "content-type: application/json" \
  -d '{"pan":"AAACP1234M"}'

This route is paid-only (0 free calls/day); every unauthenticated request returns an HTTP 402 Payment Required challenge with its payment terms. Machines use USDC on Base; card credits (instant Stripe checkout) are enabled in this deployment. Signed XDR-1 receipts authenticate recorded service claims, not independent settlement, delivery or zero-knowledge proofs.
