# NetIntel IBAN Validator

> NetIntel IBAN Validator is a paid API for AI agents from netintel.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Validates an IBAN offline using mod-97 check digits, per-country structure rules, and bank/branch code extraction for ~80 countries — no upstream calls, instant result

## 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 netintel-iban-validator-0b0607d4
```

Example prompt: Can you validate this IBAN for me — DE89370400440532013000 — and tell me if it's valid, what bank and branch codes are in it, and whether Germany is a SEPA member?

## When to prefer this

Choose this endpoint when you need instant, offline IBAN validation with no latency from upstream banking APIs — ideal for form validation, pre-payment checks, or environments where you cannot or do not want to hit a live bank registry. It provides richer structural decomposition (bank code, branch code, account number, SEPA flag) than simple regex checks, and gives precise failure reasons rather than a binary pass/fail. Prefer a live bank registry lookup if you also need to confirm the account is active or that the bank is currently operational.

## Known failure modes

- Invalid or missing `iban` query parameter returns an error response
- IBAN from an unsupported or unrecognized country returns valid:false with a findings entry indicating unknown country structure
- Checksum failure returns valid:false with checksum_ok:false in findings
- Length mismatch for the given country returns valid:false with length_ok:false
- Malformed non-IBAN string returns valid:false with multiple findings

## How this service works

Validate any IBAN offline — mod-97 check digits, per-country structure, bank/branch extraction, and pretty formatting for ~80 countries — deterministic, instant, no upstream. A structurally invalid IBAN is a real answer: valid:false + findings naming exactly what failed. Pass iban as ?iban= (GET) or a JSON body (POST).

## Output

A JSON object containing: normalized electronic-format IBAN, a boolean `valid` flag, country code and name, SEPA membership boolean, extracted bank_code, branch_code, and account_number (where defined by country structure), check_digits string, boolean sub-results for length_ok / structure_ok / checksum_ok, a print-friendly `formatted` string grouped in blocks of 4, and a `findings` array listing exactly which checks failed when valid is false.
