Install Jentic One Beta

Connect the Afterbanks API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Afterbanks API, 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fafterbanks.com%2Fafterbanks" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fafterbanks.com%2Fafterbanks" | 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.

Transaction Analysis

A financial agent can pull a connected account's transaction history in a normalized format and categorize spending, detect recurring charges, or feed a budgeting model. Because the data is consistent across banks, the same logic works regardless of the underlying institution. The agent reads only the accounts the user has connected.

Pull the last 90 days of transactions for the connected account and categorize spending

Multi-Bank Financial Overview

For users with accounts at several banks, an agent can aggregate balances across all connected institutions into a single overview. This gives a consolidated financial picture without the user logging into each bank. The agent refreshes the data on demand when the user asks.

Aggregate balances across all of the user's connected banks into one summary

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Afterbanks API by hand means registering for a service key, attaching it to every request, and handling the bank-connection flow and normalized response format yourself. Through Jentic you install once, import Afterbanks from the API Directory, store the key once, and your agent calls it.

Permission scoping

Afterbanks carries the connection target in the request body rather than the URL path, so rules bound which operations the agent may call rather than which bank. You can allow reading accounts and transactions while withholding other operations.

Credential isolation

Your Afterbanks service key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'aggregate bank accounts' or 'pull transaction history', and Jentic returns the matching Afterbanks operation with its input schema so the agent calls the right endpoint without reading the reference docs.

FAQs

Specific to using Afterbanks API through Jentic.

Is there an Afterbanks MCP server?

You don't need an MCP server to connect your agent to the Afterbanks API. Jentic imports it from the API Directory, stores your service key once, and your agent aggregates accounts and transactions directly. No extra server sits in the agent's context.

Can I limit what my agent is allowed to do with the Afterbanks API?

Yes. Afterbanks exposes a small set of operations for listing banks, authenticating, and pulling data, and you choose which the agent may call. You can allow it to read accounts and transactions while withholding anything else. Requests carry the target in the body rather than the URL path, so rules bound which operations the agent may use. Every call is logged.

What authentication does the Afterbanks API use?

The Afterbanks API authenticates with a service key that identifies your account on each request. Through Jentic the service key is stored encrypted by your own Jentic One instance and injected when the agent makes a call, so it never appears in the agent's prompt or logs.

Can my agent pull transactions from multiple banks with the Afterbanks API?

Yes. Afterbanks normalizes data across the banks it supports, so an agent can connect several of a user's banks and retrieve their accounts and transactions in one consistent format.

What are the rate limits for the Afterbanks API?

The OpenAPI spec does not specify rate limits. Check the Afterbanks documentation for the current limits before scaling an agent's data pulls.

How do I aggregate a user's accounts with the Afterbanks API through Jentic?

Search Jentic for 'aggregate bank accounts' and it returns the Afterbanks operation with its input schema. Store your service key once, then your agent connects a bank and reads back accounts and transactions. To run it on your own infrastructure, install Jentic One from its GitHub repo.

For Agents

List supported bank connection forms, authenticate a user against their bank, and retrieve their accounts and normalized transaction history through a single aggregation API.

Use for: List the banks Afterbanks can connect to, Connect this user's bank account and fetch their transactions, Pull the latest balances for a connected account, Retrieve the transaction history for the last 90 days

Not supported: Does not initiate payments, issue cards, or provide credit scoring. Use for bank account and transaction aggregation only.

The Afterbanks API aggregates bank account and transaction data across banks. It lists the connection forms for supported banks, authenticates a user's bank login, and returns their accounts and transaction history in a normalized format, so applications can pull financial data without building a separate integration for each bank.
