## 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 moneytools-taiwan-id-arc-validator-b49853e8 -d '<json body>'
```

Example prompt: Can you check whether A123456789 is a valid Taiwan national ID number — verify the checksum and format for me?

## When to prefer this

Use this endpoint when you need lightweight, stateless checksum and format validation for Taiwan-specific identity documents (ROC ID, ARC, 統一編號) without storing any PII. Ideal for KYC pre-screening, invoice validation, and form submission checks where you only need cryptographic format correctness, not database lookup against government records. Prefer over building your own logic given support for all three ID types including the 2021 new ARC format and the updated ÷5 統一編號 rule.

## Known failure modes

- Malformed or empty 'id' field returns a validation error
- ID with wrong length for its apparent type fails format check
- 統一編號 that doesn't pass mod-10 or new ÷5 rule returns invalid
- Ambiguous strings that match no known format return unrecognised type
- Rate limit exceeded on free tier (10/day) without payment credentials returns 402 Payment Required
- Invalid or exhausted API key returns authentication error

## How this service works

Taiwan ID / ARC / 統一編號 checker: Checksum and format for 國民身分證, 居留證 (old and 2021 new format) and 統一編號 (company tax ID, new ÷5 rule). Not stored. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
