# Indian PAN Validator

> Indian PAN Validator is a paid API for AI agents from toll402.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Offline validates an Indian Permanent Account Number (PAN) by normalizing case, checking the 10-character AAAAA9999A format, and verifying the holder-type character against the official enum.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability indian-pan-validator-4da528ea -d '<json body>'
```

Example prompt: Can you check if ABCPD1234E is a valid Indian PAN number and tell me what type of entity it belongs to?

## When to prefer this

Use this endpoint when you need a fast, offline, zero-latency check of whether a string conforms to the Indian PAN format and want to extract the holder type — ideal for pre-submission form validation, KYC pipelines, or agent workflows where you need a structural check before hitting a live government API. Not suitable when you need live government database verification of PAN existence or ownership.

## Known failure modes

- PAN string shorter or longer than 10 characters returns invalid format error
- Non-alphabetic characters in the alphabetic positions cause validation failure
- Unknown or invalid 4th-position holder-type character returns enum mismatch error
- Missing required 'pan' field in request body returns schema validation error
- Entirely numeric or empty string input returns invalid format

## How this service works

Offline validator for an Indian PAN (Permanent Account Number): normalizes input to uppercase, checks the 10-character AAAAA9999A pattern, and validates the 4th character against the known holder-type code enum (P=Individual, C=Company, H=HUF, F=Firm, A=AOP, T=Trust, B=BOI, L=Local Authority, J=Artificial Juridical Person, G=Government). Does not verify the undisclosed final check character.

## Output

Returns whether the PAN passes format validation (matches the 10-character AAAAA9999A pattern), the normalized uppercase form, and the decoded holder-type code (e.g. P=Individual, C=Company, H=HUF, F=Firm, A=AOP, T=Trust, B=BOI, L=Local Authority, J=Artificial Juridical Person, G=Government). Does not perform live government database lookup or verify the final check digit.
