Silverfin accounting platform API for managing companies, accounts, periods, reconciliations, and financial data. The API exposes 17 endpoints secured with oauth2 authentication.
Install Jentic One Beta
Connect the Silverfin API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Silverfin 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%2Fsilverfin.com%2Fsilverfin" | sh2
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%2Fsilverfin.com%2Fsilverfin" | sh
jentic register # connects your agent to your Jentic One instanceJentic 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.

Use Cases
Patterns agents use Silverfin API for, with concrete tasks.
★ Finance and Accounting Operations
Use the Silverfin API to perform finance operations programmatically. The API provides 17 endpoints covering core functionality including create company, list companies, update company.
Call POST /companies to create company
Automated Accounts Management
Automate accounts operations by combining multiple Silverfin API endpoints. Agents can list companies and then update company in a single workflow.
Call GET /companies to list companies, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Silverfin API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle oauth2 tokens manually.
Search Jentic for 'create company', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring Silverfin by hand means running its OAuth2 authorization-code flow with a firm-scoped token URL and pointing calls at https://developer.silverfin.com/api/v4. Through Jentic you install once, import Silverfin from the API Directory, store the credential once, and your agent calls it.
Permission scoping
Silverfin puts the company id in the URL path (/companies/{id}), so a rule can pin your agent to one company: it can read that company, its users, and its accounts and nothing else. You choose the operations it may call, so destructive ones like deleting a company are not included unless you add them.
Credential isolation
Your Silverfin credential 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 'create a company' or 'list a company's accounts', and Jentic returns the matching Silverfin operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Silverfin API through Jentic.
What authentication does the Silverfin API use?
The Silverfin API uses OAuth 2.0 for authorization. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I create company with the Silverfin API?
Yes. Use the POST /companies endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Silverfin API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I create company through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create company'. Jentic returns the matching Silverfin API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Silverfin API have?
The Silverfin API exposes 17 endpoints covering accounts, adjustments, companies operations.
Can I limit what my agent is allowed to do with the Silverfin API?
Yes. Because you run Jentic One yourself, your own rules decide which Silverfin operations and credentials the agent may use. Since Silverfin puts the company id in the URL path, such as /companies/{id}, you can pin the agent to a single company so it can read that company, its users, and its accounts and nothing else. You also choose exactly which operations it may call, so destructive actions like archiving a company via DELETE /companies/{id} are excluded unless you add them.
