How this service works
Call when an agent needs whether an IBAN is a mod-97-valid DE number of length 22. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-iban-de first.
Output
Returns a boolean or structured response indicating whether the provided string is a valid German (DE) IBAN: correct country prefix, exactly 22 characters, and passing the mod-97 checksum algorithm.
Example use cases
Pre-transfer IBAN sanity check
“Before I send a wire, can you verify that DE89370400440532013000 is a valid German IBAN with the correct length and mod-97 checksum?”
Onboarding bank account verification
“A new supplier just gave us their German bank account IBAN DE12345678901234567890 — can you validate it before we add it to our payment system?”
Batch data cleanup validation
“I have an IBAN from our database that may be corrupted: DE00123456780000012345 — can you check if it's a properly valid 22-character German IBAN?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-de?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a German (DE) IBAN for format correctness and mod-97 checksum compliance. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-de first to avoid charges. Use this paid endpoint for production validation or when sandbox access is unavailable. For other country IBANs (e.g. MU), use the appropriate country-specific sibling endpoint on the same platform.
Side effects
- Input is not a string or is empty — request rejected
- IBAN has wrong country prefix (not DE) — validation fails
- IBAN is not exactly 22 characters — validation fails
- Mod-97 checksum does not compute correctly — marked invalid
- Malformed or non-numeric characters cause parsing errors
- Service unavailable or payment not processed — HTTP 402 or 5xx returned
