How this service works
Safety and trust layer for AI agents: PII redaction, scam/phishing text scan, EVM/Solana address validation, IBAN checks, JSON repair, deep on-chain wallet risk scoring, x402 counterparty endpoint reputation checks. Free discovery: /openapi.json, /.well-known/x402, /v1/capabilities, /mcp (tools/list). REST + MCP. Pay with USDC via x402 — no API keys.
Output
A JSON object with a boolean 'valid' field indicating structural IBAN validity, and a 'country' field containing the two-letter ISO country code extracted from the IBAN (e.g. {"valid": true, "country": "DE"}).
Example use cases
Payment form IBAN verification
“A user just typed in their bank account IBAN as GB29NWBK60161331926819 — can you validate it before I let them proceed to checkout?”
Compliance check for wire transfer
“Before we wire money to this account, please verify that IBAN FR7630006000011234567890189 is correctly formatted and from a valid country.”
Detecting invalid IBAN in user onboarding
“We have an IBAN submitted during onboarding: NL91ABNA0417164300 — can you confirm it's valid so we can finish setting up this user's bank details?”
Technical details
Endpoint
GEThttps://agent-guard.annushka1190.workers.dev/v1/iban/validateWhen to prefer
Choose this endpoint when you need a fast, cheap, no-key-required IBAN structural validation as part of a payment or compliance workflow — especially useful in AI agent pipelines that already use x402/USDC micropayments and need to guard against bad bank account numbers before initiating transfers. Prefer this over rolling your own regex or a heavier KYC/banking API when all you need is format and country validation.
Side effects
- Missing or empty IBAN query parameter — returns invalid or error response
- Malformed IBAN with wrong length or invalid characters — returns valid: false
- Unsupported or unknown country prefix — may return valid: false or partial result
- Payment not sent or insufficient USDC — returns 402 Payment Required
- Network timeout on Cloudflare Worker — returns 5xx error
