IBAN Validator API

maximedupre/iban-validator

Validate IBANs in one run with country structure checks and the ISO 13616 MOD-97 checksum. Get the submitted value, normalized formats, country details when available, SEPA membership, and a clear diagnostic status for each row.

Bulk IBAN Validator & Formatter, Offline

comall-agency/iban-validator-formatter

Validate IBANs fully offline: country length from the ISO 13616 registry (78 countries), mod-97 checksum, BBAN extraction and clean 4-character formatting. The verdict says why a value failed, and expected_length beside actual_length makes a bad paste obvious. No bank lookup.

IBAN Validator: Verify & Bulk-Check Bank IBANs

apifmcpfactory/iban-validator

Validates IBANs offline against the official ISO 13616 mod-97 checksum and per-country structure — instant, no bank API, no data ever leaves the run. Bulk-clean a customer or supplier IBAN list before a payment run; $0.005 per IBAN checked.

Validate IBANs and BIC/SWIFT codes offline: ISO 13616 mod-97 checksum and per-country BBAN structure for IBANs, format parsing for BICs. Checksum-valid IBANs are enriched with bank name, BIC, and address from openiban.com when available. Charged only on success — never for malformed input.

Bulk Username Checker: GitHub, GitLab, Docker

comall-agency/username-osint-checker

Check whether a username exists on GitHub, GitLab, Docker Hub, Keybase and Hacker News in a single call, through each platform's own public API. No login and no scraping. A platform that times out is reported as unknown, never collapsed into not-found.

Bulk French E-Invoice Resolver: SIRET, VAT

comall-agency/fr-einvoice-partner-resolver

Resolve a French business partner from a SIRET, SIREN or intra-EU VAT number, for the party blocks of a Factur-X invoice ahead of the 2026 e-invoicing mandate. Returns official identifiers and address from public registries, with the VAT state reported explicitly rather than guessed.

Bulk EU VAT Number Checker — Official VIES

comall-agency/eu-vat-checker

Confirm an EU VAT number against the European Commission's own VIES service, after a per-country format check. Returns the registered name and address when the member state publishes them. Never charged when VIES is unreachable: that verdict means try again later, not invalid.

Bulk Card Number Validator (Luhn), Offline

comall-agency/card-number-validator

Check card numbers against the Luhn checksum and detect the network (Visa, Mastercard, Amex, Discover, Diners, JCB) from the prefix. 100% offline: the number stays in memory and never reaches the output or the logs, only a masked form. Checksum only, not an authorization.

Bulk Password Strength Checker — Offline

comall-agency/password-strength-checker

Score passwords in bulk on entropy, character classes, a list of 56 of the most common breached passwords, keyboard sequences and repeated characters, with readable feedback explaining each score. 100% offline, no breach-database lookup, and the password itself is never returned in the output.

Bulk Barcode Check-Digit Validator: EAN, UPC

comall-agency/barcode-checkdigit-validator

Validate GS1 check digits for EAN-13, EAN-8 and UPC-A barcodes in bulk, or compute the missing digit for a code sent one digit short. The mode is picked per code, so mixed batches work in one run. Pure algorithm: no product database, no third-party API, no signup.
