## 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 postandshare-nigerian-bank-account-validator-db499515
```

Example prompt: Can you check whether account number 0123456789 is a valid NUBAN for bank code 058 (GTBank) in Nigeria?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call format and reference validation of Nigerian NUBAN bank account numbers without performing a live identity lookup or name resolution. Ideal for fintech workflows, payroll systems, or payment pipelines operating in Nigeria that need to pre-screen account details cheaply before committing to a full bank API call. Prefer this over a full account name enquiry API when only structural validity is needed and cost per call matters.

## Known failure modes

- Invalid or non-existent CBN bank code returns an error indicating unrecognized bank
- Account number not exactly 10 digits returns a format validation error
- Missing required parameters (bank_code or account_number) returns a 400 bad request
- Payment not included or invalid x402 payment header returns a 402 Payment Required
- Network timeout or service unavailability returns a 503 or connection error

## How this service works

x402 pay-per-call data endpoints for AI agents: multi-chain reads (Base, Ethereum, Arbitrum, Polygon) and Nigerian reference data. Format/reference validation only — no personal data, no identity-database lookup.

## Output

Returns a validation result indicating whether the provided 10-digit NUBAN account number is structurally valid for the given 3-digit CBN bank code. This is a format and reference check only — no personal name or identity data is returned.
