## 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 toll402-indian-cin-validator-630e8a91 -d '<json body>'
```

Example prompt: Can you check whether this Indian company CIN is structurally valid: L17110GJ1973PLC011243? I want to know if the listing status, state code, NIC code, company type, and registration number all look correct.

## When to prefer this

Use this endpoint when you need fast, offline, zero-external-dependency structural validation of Indian CINs — no network call to MCA, no checksum (none exists), purely format and enum correctness. Ideal for pre-submission validation in onboarding flows, KYC pipelines, or data quality checks where you want to catch malformed CINs cheaply before hitting authoritative registries.

## Known failure modes

- CIN not exactly 21 characters — returns invalid format error
- Invalid listing status letter (not L or U) — flags first character
- Unrecognized state code not in MCA list — flags state code field
- Implausible incorporation year (e.g. before 1800 or future date) — flags year field
- Unknown company type code not in known enum — flags company type field
- Non-numeric characters in NIC code, year, or registration number — flags respective field
- Empty or missing input value — returns missing input error

## How this service works

Offline structural validator for an Indian CIN (Corporate Identity Number, 21 characters). Parses and checks: listing status letter (L/U), 5-digit NIC industry code, 2-letter state code (against the known MCA state-code list), 4-digit incorporation year (plausible range), 3-letter company-type/ownership code (against a known enum like PLC, PTC, OPC, GOI, NPL, FTC, SGC, ULL, ULT), and 6-digit registration number. No checksum exists so this is a format-only check.

## Output

Returns a structured validation result indicating whether the CIN string is structurally valid, along with parsed components: listing status (L/U), 5-digit NIC industry code, 2-letter state code, 4-digit incorporation year, 3-letter company type/ownership code (e.g. PLC, PTC, OPC), and 6-digit registration number. Flags which component failed if invalid.
