LancerIBANforge checks the bank behind an IBAN before you pay. It validates IBANs from all 89 IBAN countries and, in all but 8 of them, names the bank and its BIC, with the source of that answer. Where it reads the national register (Germany, Austria, Belgium, Slovakia, Czech Republic, Bulgaria, Switzerland and Liechtenstein), it also tells you whether the bank code is allocated at all; elsewhere it names the bank from a partial register or a composite map, and says that such an answer cannot rule a code out. For a SEPA bank it resolves, it gives the SEPA schemes that reach it (Credit Transfer, Instant, Direct Debit), from the EPC scheme registers when they list the bank and from the country otherwise (the answer says which), and says whether the EPC Verification of Payee (VoP) register lists the bank as ready to answer VoP requests. It does not check who holds the account: that name check belongs to the payee's bank, through VoP.
Not a name check (VoP, BAV, CoP), not proof that an account exists or is open, not a sanctions screening of the payee (bank and country only), not a licensed copy of the SWIFT BIC directory. The national check digits inside the BBAN are checked for France and Monaco (RIB key), Belgium, Italy and San Marino (CIN), Spain (DC), Germany (the account-number check digit, by the Bundesbank method of each bank code) and the United Kingdom (modulus check): a wrong key shows in checks.national_check_digits and never turns valid to false. The Polish settlement-number check digit is checked with the bank code. The national keys of the other countries are not checked yet.
For business software and AI agents alike: a REST API, a native MCP server, prepaid packs by card, and x402 micropayments with no signup.
89 IBAN countries · bank codes checked against the national registers of DE, AT, BE, SK, CZ, BG, CH, LI · 121k+ BIC entries (39k+ LEI via GLEIF; about two thirds a public copy of the SWIFT directory frozen in January 2018) · 1,100+ Swiss BC-Nummern (SIX)
Add to your MCP config (~/Library/Application Support/Claude/claude_desktop_config.json for Claude Desktop):

"mcpServers": {
"ibanforge": {
"command": "npx",
"args": ["-y", "ibanforge-mcp"]

}
Privacy by default: submitted IBANs are never stored — validation runs in memory, IPs are kept only as salted hashes, and telemetry deletes itself (12-month cap; erased 30 days after a customer terminates, contractually — DPA clause 4.7).
Optional: set IBANFORGE_API_KEY=ifk_... in env (a key that needs no e-mail: 25 requests a month, raised to 200 a month once claimed). Without it the server uses the public/demo surface; combine with x402 micropayments for unlimited pay-per-call access without signup.

Content-Type: application/json
Accept: application/json, text/event-stream
Authorization: Bearer ifk_your_key # optional
Standard JSON-RPC initialize + tools/list + tools/call flow. Use this when stdio is not an option (CI/CD, serverless, Vercel agents, etc.). Without a key it answers a keyless allowance per source address; with a key (Authorization: Bearer or X-API-Key), the tool calls count against that key exactly as on the REST API.
The free tools need no key, no wallet and no signup: they are the ones to try first. The last two are the way out of the free allowance without anyone typing an address — they keep answering after the allowance is spent.
Full descriptions of the read-only data tools, with WHEN-to-use triggers, are served live at /.well-known/mcp/server-card.json.
If you can open a web address but cannot send a POST (no code execution, no MCP connector), these pages hold real answers of the API, each with its date, and all of them open with a plain GET.
Do not simulate answers from the API: quote these real ones, with the date each carries (served_at, as_of, or the date of the page). To get answers on the IBANs of your user, ask them to add https://api.ibanforge.com/mcp as a custom connector in their assistant; where to click, assistant by assistant: https://ibanforge.com/docs/mcp. A connector with no key draws on the same keyless allowance as any other caller, counted per source address. In Claude its calls leave from Anthropic's cloud, not from the user's device (Anthropic's documentation), so that allowance is shared with other users and may already be spent; other assistants were not checked by us. With a key, the hosted endpoint counts the calls against that key, as the REST API does: in Claude, the user adds the request header Authorization: Bearer followed by the key when creating the connector; ChatGPT sends no key to a connector (OpenAI's documentation). A POST to https://api.ibanforge.com/v1/keys/generate with no body returns a key, no e-mail; the npm package ibanforge-mcp reads it from IBANFORGE_API_KEY.
IBANforge is x402-native. Any agent with a wallet on Base L2 can discover, pay, and call:
GET https://api.ibanforge.com/.well-known/x402 returns the full catalog (endpoints, prices, asset, payTo, accepts).POST /v1/iban/validate without auth → API replies 402 Payment Required with x402 v1 challenge.No human in the loop, no sales call, no card. See the x402 spec.
Pick your language:
The Python SDK ships with sync + async clients, typed exception classes, and a free-tier quota fallback to x402 baked in:
from ibanforge import IBANforge
# 1-line key, no e-mail: 25 requests a month, 200 once claimed
key = IBANforge.generate_api_key() # shown ONCE: store key["api_key"] now
with IBANforge(api_key=key["api_key"]) as client:
out = client.validate_iban("DE89370400440532013000")
print(out["country"]["code"]) # DE
print(out["bic"]["bank_name"]) # Commerzbank
print(out["bank_code_check"]["authoritative"]) # True (checked against the Bundesbank register)
# Or the free format-only check (mod-97 + structure, no DB hit)
out = IBANforge().format_iban("DE89370400440532013000")
# Validate IBAN — no key needed for the first 25 calls a week per source address

/llms.txtnot_allocated; partial lists for Finland (Finance Finland), Italy (Banca d'Italia, with the codes it has struck off and their legal successor), San Marino (BCSM) and Luxembourg (ABBL), where a miss is not a refusalvop.csv), refreshed weekly with the other compliance listsIntl.DisplayNames APISome of these sources may be served but not redistributed: the EBA STEP2 and NBP directory rows, the OeNB, NBB and BCSM registers, the Bank of England PRA list, the UN list and the EPC registers. So are the Polish, Finnish and Luxembourg keys of the composite bank-code map and the Finance Finland list. They are not in this repository: the hosted API loads them from a private repository, and a deployment without them answers "not consulted" where they would have spoken, never "no". See NOTICE.
The keys of the composite map that came from sources granting no right to reuse them were removed on 29 September 2026, from this repository and from the service: all of them for the United Arab Emirates, Bosnia and Herzegovina, Estonia, Georgia, Kazakhstan, Moldova, Serbia and Türkiye, whose bank codes now answer "not consulted" with no BIC, part of them for Spain and Italy, and those of Romania. Where open data names one BIC, the Italian and Romanian ones were rebuilt from it (the Banca d'Italia's LEI and GLEIF, scripts/derive-map-keys.ts); the other Italian keys, taken from national files or added by hand, are unchanged. The Slovenian, Lithuanian, Hungarian and Croatian keys come from those countries' central banks, and every answer built from them carries the credit each asks for in bic.source.
