How this service works
Network intelligence API — 142 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
Returns a JSON object with: normalized electronic-format IBAN, a top-level `valid` boolean, individual pass/fail flags for checksum, structure, and length, SEPA membership status, parsed components (bank code, branch code, account number, check digits), human-readable country name, print-formatted IBAN grouped in 4s, and a `findings` array listing any detected issues.
Example use cases
Payment form IBAN pre-validation
“Before we process this wire transfer, check if GB29NWBK60161331926819 is a valid IBAN and confirm it's SEPA-eligible.”
Fintech onboarding bank account check
“A user just entered FR7630006000011234567890189 as their bank account — can you validate it, tell me if the checksum passes, and extract the bank code and account number?”
Fraud screening for suspicious account
“I need to check this IBAN that came through on a suspicious invoice: IT60X0542811101000000123456 — is it structurally valid, does the checksum check out, and what country is it from?”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/iban/validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, component-level IBAN validation — not just a regex check — including checksum verification (mod-97 algorithm), country-specific length and structure rules, SEPA membership status, and parsed bank/branch/account components. Prefer it over generic format validators when you need structured output suitable for downstream payment processing, fraud detection, or fintech onboarding flows. No API key or signup required; billed per call via x402 micropayments and never charged on failed or invalid-input calls.
Side effects
- Missing `iban` query parameter — returns validation error, no charge
- Completely garbled input that cannot be parsed as an IBAN — returns valid:false with findings explaining the issue
- Unsupported or unrecognized country prefix — valid:false with structure_ok:false
- Network/upstream error — returns server error, no charge per NetIntel policy
