How this service works
Call when an agent needs whether an IBAN is a mod-97-valid ST number of length 25. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/check-iban-st first.
Output
Returns a boolean or structured result indicating whether the provided string is a valid mod-97 IBAN for São Tomé and Príncipe (ST), confirming the correct country code prefix, exact 25-character length, and passing checksum.
Example use cases
Validate ST bank account before wire
“Before I send this international wire, can you confirm that ST68000100010051845310146 is a genuinely valid São Tomé and Príncipe IBAN — correct length, country code, and mod-97 checksum?”
Fintech onboarding IBAN verification
“A user just entered ST12000100010051845310199 as their bank account number during onboarding — can you validate it's a properly formatted and mod-97-correct ST IBAN before we save it?”
Bulk payment data quality check
“I have this IBAN from my payment records: ST68000100010051845310146 — can you verify it's structurally valid for São Tomé and Príncipe so I know whether to flag it for review?”

Endpoint

Use this endpoint when you specifically need to validate an ST (São Tomé and Príncipe) IBAN. It is narrowly scoped to ST IBANs and combines country code, length (25), and mod-97 checksum validation in a single call. Try the free sandbox endpoint (/v1/sandbox/check-iban-st) first to avoid unnecessary charges. Choose the corresponding country-specific sibling endpoints for other IBAN country codes (LT, LU, LV, MK, MR, PK, PS, etc.).
Side effects

- IBAN is not exactly 25 characters — returns invalid
- Mod-97 checksum fails — returns invalid
- Malformed input exceeding maxLength — rejected by schema
- Non-string or unexpected data type input — returns error
