For Agents

Install Jentic One Beta

Connect the Swiss NextGen Banking API-Framework to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Swiss NextGen Banking API-Framework, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

View OpenAPI Document

The Swiss NextGen Banking API-Framework is the Swiss edition of the Berlin Group NextGenPSD2 specification, defining a harmonised XS2A interface that banks (ASPSPs) and Third Party Providers can use to exchange payment, account, and consent data. It covers Payment Initiation Service (PIS), Account Information Service (AIS), Confirmation of Funds Service (PIIS), and Signing Baskets, plus shared common services for consent and authorisation. Strong Customer Authentication is supported through Redirect, Decoupled, Embedded, and OAuth approaches, though the obp.ch community recommends Redirect SCA. The framework underpins open banking interoperability for Swiss banks while remaining compatible with the wider Berlin Group ecosystem.

Use Cases

Patterns agents use Swiss NextGen Banking API-Framework API for, with concrete tasks.

★ Swiss XS2A Payment Initiation

Initiate Swiss SEPA, instant, and cross-border payments from customer accounts through a single Berlin Group NextGenPSD2 interface. The /v1/{payment-service}/{payment-product} endpoint accepts the payment service (e.g. payments, periodic-payments) and product (e.g. sepa-credit-transfers, instant-sepa-credit-transfers) as path segments, with Redirect SCA handling the customer authorisation step.

POST /v1/payments/sepa-credit-transfers with debtor IBAN CH9300762011623852957 and creditor IBAN DE89370400440532013000 for EUR 250, then redirect the user to the SCARedirect link returned in _links.

Account Aggregation

Aggregate balances and transactions across Swiss bank accounts after the customer authorises an AIS consent. The /v1/accounts, /v1/accounts/{account-id}, and /v1/accounts/{account-id}/balances endpoints expose the structured fields needed for personal finance dashboards and SME bookkeeping integrations without screen-scraping each bank's e-banking portal.

Read the active AIS consent ID, GET /v1/accounts to list authorised accounts, then GET /v1/accounts/{account-id}/balances for each to surface a unified balance view.

Signing Basket Approvals

Group multiple payment instructions into a Signing Basket so the customer authorises them in a single SCA flow rather than approving each payment individually. This streamlines bulk supplier payments and treasury batches in corporate banking integrations, with the basket lifecycle tracked through dedicated authorisation and status endpoints.

Create a signing basket referencing five pending sepa-credit-transfer payment IDs, then trigger authorisation and poll status until the basket is finalised.

AI Agent Cross-Bank Treasury

Through Jentic, an AI treasury agent can initiate payments and pull balances from any Swiss ASPSP that implements the obp.ch framework without learning each bank's portal. The agent searches for the right Berlin Group operation, loads the schema, and executes the call with bank-specific base URLs supplied via the catalogue.

Through Jentic, search for 'list Swiss bank accounts under an AIS consent', load GET /v1/accounts, and execute it with the active Consent-ID header to return all authorised accounts.

Key Endpoints

34 endpoints — the swiss nextgen banking api-framework is the swiss edition of the berlin group nextgenpsd2 specification, defining a harmonised xs2a interface that banks (aspsps) and third party providers can use to exchange payment, account, and consent data.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your OAuth bearer tokens, eIDAS QWAC certificates, and per-ASPSP client credentials are stored once, encrypted, by your own Jentic One instance and applied at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'fetch account balances under an AIS consent' or 'initiate a Swiss payment', and Jentic returns the matching Berlin Group operation with the Consent-ID and PSU-ID header schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Swiss NextGen Banking API-Framework API through Jentic.

What authentication does the Swiss NextGen Banking API use?

The spec declares an HTTP Bearer scheme (BearerAuthOAuth) - the TPP obtains an OAuth 2.0 access token and presents it in the Authorization header. On top of that, ASPSPs require eIDAS QWAC mTLS at the transport layer and the customer SCA flow (Redirect, Decoupled, Embedded, or OAuth) for payment and consent authorisations. Through Jentic, the access token and certificates stay isolated in your Jentic One instance.

Can I initiate a SEPA instant credit transfer with this API?

Yes. POST /v1/payments/instant-sepa-credit-transfers initiates an instant SEPA credit transfer; the same path pattern accepts other payment products such as sepa-credit-transfers, target-2-payments, and cross-border-credit-transfers. The Swiss edition refines message formats and adds Switzerland-specific examples while remaining compatible with Berlin Group v1.3.4.

What are the rate limits for the Swiss NextGen Banking API?

The framework itself does not mandate a single rate limit - each implementing Swiss ASPSP defines its own quotas, typically published in its developer portal. AIS reads of balances and transactions are usually limited to four unattended pulls per day per consent under PSD2 norms; PIS calls are limited per TPP rather than per consent.

How do I list authorised accounts through Jentic?

Search Jentic for 'list authorised Swiss bank accounts', load GET /v1/accounts, and execute it with the active Consent-ID header from the AIS consent flow. Jentic returns the structured account list so the agent can iterate through each account-id and call /balances or /transactions without parsing the obp.ch sandbox responses.

Is the Swiss NextGen Banking API free?

The framework specification is open and free to consume. Calling live ASPSP endpoints requires TPP authorisation under PSD2/equivalent Swiss regulation, eIDAS QWAC certificates, and per-bank onboarding - costs sit with that registration and certificate process rather than with the spec itself.

Can I cancel a payment after submission?

Yes for payments that have not yet executed: the spec exposes /v1/{payment-service}/{payment-product}/{paymentId}/cancellation-authorisations to start a cancellation authorisation sub-resource. Once an instant SEPA payment has settled it cannot be reversed through this API - settlement is irrevocable and any reversal requires an out-of-band recall.

Can I limit what my agent is allowed to do with the Swiss NextGen Banking API?

Yes. Because you run Jentic One yourself, your own rules decide which Berlin Group XS2A operations and credentials the agent may use. Since the account id and payment id sit in the URL path (/v1/accounts/{account-id}, /v1/{payment-service}/{payment-product}/{paymentId}), a rule can pin the agent to one account or one payment so it only reads that account's balances or tracks that payment's status. You choose the operations it may call, so payment initiation and authorisation endpoints stay off limits unless you explicitly add them.
