How this service works
Validate IBAN, ISBN, and similar identifiers by format and checksum (not real-world verification).
Output
Returns a validation result indicating whether the identifier conforms to the expected format and passes its checksum algorithm. Typically includes a pass/fail status and, on failure, details about which aspect of validation failed (e.g. invalid check digit, wrong length, unsupported prefix). Does not confirm real-world existence or live registry status.
Example use cases
Book ISBN validation before catalog entry
“Before I add this book to our catalog, check whether ISBN-13 9780306406157 is a valid identifier with a correct checksum.”
IBAN format check for payment processing
“Validate the IBAN GB29NWBK60161331926819 for me — I need to know if the format and checksum are correct before we submit the wire transfer.”
ISIN verification for trade compliance
“Can you verify that the ISIN US0378331005 is properly formatted and passes its checksum — we need to confirm it before booking the trade?”
Technical details
Endpoint
POSThttps://api.edifiedlab.com/v1/tools/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, offline-style format and checksum validation for structured identifiers like IBAN, ISBN, ISIN, IMEI, VATIN, EAN barcodes, LEI codes, or ISSN — particularly when you don't need live registry lookups or real-world existence confirmation. Ideal for data-quality pipelines, form validation workflows, and pre-submission checks where speed and cost matter more than authoritative verification.
Side effects
- Unsupported scheme value returns an error or unrecognized-scheme response
- Malformed input (wrong type for value) may return a 400-level error
- Validation only covers format and checksum — a structurally valid IBAN may not exist in any real bank
- Phone validation may be region-sensitive and produce false negatives without a region param
- JSON schema validation result depends on correctness of the supplied schema object
