How this service works
Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.
Output
A JSON object with a boolean 'valid' field, a human-readable 'reason' string explaining the result, a 'scope' field indicating the type of check performed (format-only vs checksum-verifiable), an optional 'normalized' field with the canonical code form, and an optional 'country' field. All checks are performed offline deterministically with no ML or external scraping.
Example use cases
Payment form currency validation
“Before processing this invoice, check if 'AED' is a valid ISO 4217 currency code so I know the currency field won't cause a rejection downstream.”
Fintech data pipeline QA
“I'm cleaning a dataset of currency codes from our ERP export — can you verify whether 'VEF' is still a recognized ISO 4217 code and what the normalized form should be?”
Crypto vs fiat code disambiguation
“Someone entered 'ETH' as a currency code in our payment form — is that a valid ISO 4217 code or not, and what's the reason it passes or fails?”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/iso4217-currency-check/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, offline validation of ISO 4217 currency codes with no dependency on external databases or ML models. Ideal for payment pipelines, compliance workflows, or data cleaning tasks where you need a signed, auditable result at minimal cost ($0.005 USDC per call after the first 3 free daily calls). Prefer this over regex-only checks when you want the 'scope' metadata to understand exactly what type of validation was applied.
Side effects
- Invalid or unrecognized currency code returns valid:false with a reason explaining the failure
- Malformed input (non-string, wrong length) returns an error response
- Payment failure via x402 if USDC balance is insufficient after the 3 free daily calls
- Network timeout if the endpoint is temporarily unavailable
