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.
Output
Returns whether the submitted ID string is valid, its detected type (national ID, old ARC, new 2021 ARC, or 統一編號), and checksum/format pass or fail details. No data is stored server-side.
Example use cases
KYC onboarding ID check
“I need to verify that the Taiwan national ID a user submitted during signup is correctly formatted and passes checksum — the number is F234567890, can you check it?”
Company tax ID validation
“Before I process this invoice, can you confirm that 12345675 is a valid Taiwan 統一編號 that passes the new divide-by-5 rule?”
ARC new-format verification
“Can you check whether this Taiwan resident certificate number A800000014 is a valid ARC under the 2021 new format?”
Technical details
Endpoint
POSThttps://tools.moneytools.dev/v1/tw-id?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
