# Postandshare Nigerian Identity Format Validator

> Postandshare Nigerian Identity Format Validator is a paid API for AI agents from api.postandshare.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Validates the format of Nigerian identity numbers (NIN, BVN, TIN, CAC_RC, CAC_BN) without performing a live identity database lookup

## 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-identity-format-validator-1a6b126e
```

Example prompt: Can you check whether the NIN number 12345678901 is correctly formatted according to Nigerian standards?

## When to prefer this

Use this endpoint when you need a lightweight, privacy-safe check that a Nigerian identity number is structurally well-formed before submitting it to a live KYC or identity verification service. It does not touch any identity database, making it safe for early-stage validation without privacy or compliance risk. Prefer this over full identity lookup endpoints when you only need to catch obvious formatting errors or typos.

## Known failure modes

- Missing or invalid 'type' enum value — returns error if type is not one of NIN, BVN, TIN, CAC_RC, CAC_BN
- Missing 'value' field — returns error if no number string is provided
- Malformed number string — returns format-invalid response rather than an error
- Payment failure via x402 — returns 402 if USDC payment is not attached
- Rate limiting or server errors — may return 429 or 5xx

## How this service works

Agent-callable Solana token launch, for agents that need to create, launch or rug-check a Solana SPL token or meme coin: plan a token launch free, build a complete unsigned create-token transaction (mint + Metaplex metadata + supply + authority revoke) for the caller's own wallet to sign, and audit any existing mint's authorities. Non-custodial — no private key is ever accepted, held or transmitted. Also multi-chain EVM reads (Base, Ethereum, Arbitrum, Polygon) and Nigerian phone/NUBAN/identity reference data, none of which return personal data.

## Output

Returns a format validation result indicating whether the supplied identity number matches the expected pattern and structure for the specified Nigerian identifier type (NIN, BVN, TIN, CAC_RC, or CAC_BN). Does not perform a live lookup against any government or identity database — only checks structural correctness.
