open-banking.io

open-banking-io (Python)

Server-to-server client for open-banking.io. It authenticates with your API key and decrypts the zero-knowledge data envelopes locally with your exported private key — the service only ever returns ciphertext it cannot read.

pip install open-banking-io

from open_banking_io import OpenBankingClient

# Load the credentials .json you exported from the app (API key + private key).
with OpenBankingClient.from_credentials("credentials.json") as client:
    for account in client.get_accounts():
        booked = next((b for b in account.balances if b.type == "ITBD"), None)
        label = account.display_name or account.owner_name
        print(f"{label} {account.iban}: {booked.amount if booked else None} {account.currency}")

        page = client.get_transactions(account.id, limit=50)
        for t in page.items:
            print(f"  {t.booking_date}  {t.creditor_name or t.debtor_name}  {t.amount} {t.currency}")

    # Trigger an online sync (decrypts the account uid locally and posts it):
    client.sync(account.id)

Or construct it explicitly:

client = OpenBankingClient(api_base_url, api_key, private_key_pkcs8)

API

  • get_accounts() -> list[Account] — decrypts each account's envelope, display name and balances.
  • get_transactions(account_id, *, date_from=None, date_to=None, limit=None, offset=None) -> TransactionPage
  • get_connections() -> list[Connection]
  • sync(account_id) -> SyncResult — decrypts the account uid locally and posts it.
  • sync_all() -> SyncAllResult — syncs every account that has an active session.

Amounts are exposed as decimal.Decimal. Models are plain @dataclasses.

When the client constructs its own httpx.Client it applies a default 30s timeout and sends a User-Agent: open-banking-io/python/<version> header on every request (a caller-supplied client is left untouched).

Encryption

Envelopes use ECDH P-256 → HKDF-SHA256 → AES-256-GCM. Decryption requires the private key from your credentials bundle and happens entirely in-process. Full wire format and the other language clients: repo README · THREAT_MODEL.md.
