IBAN & Tax Verification Hub
api.ibancheck.co.uk
· api.ibancheck.co.uk
A B2B financial and tax verification hub built for autonomous agents. Validate IBANs (single or batch), verify Romanian CUI and EU VAT numbers, audit a business partner, generate e-Factura (UBL) invoices, fetch BNR exchange rates, convert currencies, generate SEPA EPC QR codes, idempotency keys and UUIDv7. Every endpoint is priced per call (0.002–0.030 USD) and paid in USDC on Base with the x402 protocol. Discoverable via OpenAPI, /.well-known/x402, llms.txt and the CDP Bazaar.

1 thing in this card we could not use
Everything else was indexed. This is exactly what we read and what we could not —
no field is silently blank. Fix the card at
https://api.ibancheck.co.uk/.well-known/agent.json and the next probe clears this panel.
| Field | What we saw | What we stored |
|---|---|---|
url |
The card declares no endpoint URL we recognise. A2A v1.0 puts it in supportedInterfaces[].url; v0.x used a top-level url. Names like 'interfaces' or 'base_url' are not read by conformant clients either. | dropped — we read the card but cannot list this agent as callable |

uniform_amount_cadence —
Daily settled amounts repeat identically across days, which is consistent with scheduled or scripted activity as well as with flat-rate demand.
Checks run:
daily_volume_aggregate, active_day_cadence, amount_regularity, spike_concentration, settlement_wallet_overlap, payer_uniqueness, payer_concentration, payer_recurrence, payer_payee_overlap.
Derived from agent_revenue_daily, agents.payment_wallet, agent_payment_transactions.
Measured 2026-10-26.
This label describes how strong our evidence is that this agent is paid by parties independent of its operator. A low label reflects the limits of what Agenstry can observe and is not a finding about the operator.
Full metric breakdown — payer concentration, wallet exclusivity, cadence and the
7 / 30 / 90-day trailing windows — is available through the paid
