An alternative to IBANAPI
IBANAPI is an IBAN validation API with a free plan and a self-hosted option. If you are weighing it against IBANforge, here is what each one does, with the prices of both.
We sell IBANforge, so read this page with that in mind. Every fact about IBANAPI comes from its public pages, read on 24 September 2026 and linked at the bottom. If something is wrong or a price has changed, write to support@ibanforge.com and we will correct it.
What IBANAPI does well
- A free plan with no card required: 100 basic credits and 20 bank-lookup credits per 30 days, and the free plan renews automatically.
- A self-hosted version: IBANAPI states that its validation engine can run inside your own infrastructure, with no per-request calls.
- For some countries, IBANAPI announces a check of the domestic account number itself.
- IBANAPI announces 90 countries, with bank names and BIC codes sourced from central bank registries. It resolves the bank code inside the IBAN against its own registry, built from central banks, SEPA data and manual review, and returns the BIC where available.
What a bank code missing from IBANAPI’s registry means (allocated to nobody, or simply not listed) is not stated on the pages we read.
What IBANforge does differently
- The bank code is checked in the national register where we read it in full: Germany (Deutsche Bundesbank, edition of September 2026), Switzerland and Liechtenstein (SIX BankMaster, valid from 1 September 2026), Austria, Belgium, Slovakia, the Czech Republic and Bulgaria. There, a code the register does not hold comes back not_allocated, with authoritative: true.
- Every answer names its sources: the register behind the bank-code verdict, the source of the BIC and the edition it was read from (bank_code_check.register, bic.source, as_of).
- National check digits inside the account number, where a country has them: France and Monaco (RIB key), Belgium, Italy and San Marino (CIN), Spain (DC) and the United Kingdom (modulus check).
- Built for AI agents: an MCP server, hosted or as the ibanforge-mcp package, and x402, which lets an agent pay each call in USDC on Base with no account.
- A keyless trial of 25 validations a week on POST /v1/iban/validate, to try it before taking a key.

Calculation. For 2,000 validations with bank data, from the published prices: at IBANforge, $8 in prepaid credits (two packs of 1,000) that never expire.

When IBANAPI is the better choice
- You want to run the validation engine inside your own infrastructure.
- You need the domestic account number checked in the countries where IBANAPI announces it. IBANforge does not check the German account-number methods yet.
What IBANforge does not do
- Check the account holder’s name. That is Verification of Payee, run by the payee’s bank.
- Check the German account-number methods, or the national keys of the countries not named above: not yet.
- Say whether the account exists or is open. No register publishes that.
