## 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 nigeria-nin-validator-e820e4ad -d '<json body>'
```

Example prompt: Can you check whether the NIN '12345678901' is a valid Nigerian National Identification Number?

## When to prefer this

Use this endpoint when you need a fast, cheap, offline structural validation of a Nigerian NIN — ideal for form validation, KYC pre-screening, or data cleaning pipelines where a live registry lookup is unnecessary or unavailable. Prefer this over live government API checks when speed and cost matter and format-level correctness is sufficient.

## Known failure modes

- Non-numeric or malformed input returns invalid/false result
- Input with wrong digit count (not 11 digits) fails validation
- Network or payment failure returns HTTP 402 or 5xx error
- Empty or null value input triggers a schema validation error

## How this service works

The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.

## Output

Returns a validation result indicating whether the provided NIN string conforms to the expected Nigerian National Identification Number format (11 digits, correct structure), along with any parsing or normalization details — all computed offline without hitting a live government registry.
