Lazard Frères Banque API Access & Open Banking

Lazard Frères Banque is a Paris private and merchant bank, and open-banking.io lets you reach its account data without the paperwork usually tied to PSD2. There are no eIDAS certificates to buy, no bank sponsorship to arrange, and no infrastructure to maintain — just your own dashboard and a decryption key that never leaves your device. open-banking.io reaches 2,600+ banks across the EU and UK, so a Lazard Frères Banque connection sits alongside every other institution you use.

Both business and personal Lazard Frères Banque accounts are supported, and a single consent stays valid for up to 180 days before you re-approve. Lazard Frères Banque does not publish a BIC in our directory (BIC: n/a), but that is not needed — you select the bank by name inside the dashboard.

How to connect Lazard Frères Banque

Connecting happens entirely in the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up for open-banking.io and open the web dashboard.
  2. Set your encryption passphrase. Your keys are generated locally on your own device, so only you can later decrypt your data.
  3. In the dashboard, pick Lazard Frères Banque and choose the account type — business or personal.
  4. You are redirected to Lazard Frères Banque's own secure login and consent screen, where you approve access directly with the bank (standard PSD2 consent).
  5. Your approved accounts sync back into your dashboard, ready to view.

That's the whole flow — the bank authenticates you, never open-banking.io.

Access your data

Reading data programmatically is an optional developer step after the connection exists. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext; without your private key, nothing is readable.

This is what zero-knowledge means: open-banking.io servers hold only your public key and can never read or decrypt your Lazard Frères Banque data. Pricing is around EUR 3/month.

Do I need an API key to connect Lazard Frères Banque?

No. Connecting is done in the dashboard via the bank's own login. API keys only matter later, for reading data in code.

Can the CLI connect my Lazard Frères Banque account?

No. The CLI and SDK only read or sync connections you have already approved in the dashboard — there is no connect command.

How long does access last?

Up to 180 days per consent, after which you re-approve on Lazard Frères Banque's consent screen.
