For Agents
Programmatically get access token, list resources. Covers 3 operations with apiKey authentication.
Use for: I need to access token, I want to resources, Search for resource, List all records from Sage Accounting API
Not supported: Does not handle payments, communications, or crm - use for finance and accounting only.
Accounting and business management software. The API exposes 3 endpoints secured with apiKey authentication.
Install Jentic One Beta
Connect the Sage Accounting API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Sage Accounting 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%2Fsage.com%2Fsage" | 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%2Fsage.com%2Fsage" | 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.
Capabilities
What an agent can do with Sage Accounting API.
Get access token
List resources
Integrate Sage Accounting API into automated workflows
Query and filter Sage Accounting API records by parameters
Monitor Sage Accounting API operational status and events
Use Cases
Patterns agents use Sage Accounting API for, with concrete tasks.
★ Finance and Accounting Operations
Use the Sage Accounting API to perform finance operations programmatically. The API provides 3 endpoints covering core functionality including get access token, list resources, get resource.
Call POST /auth/token to get access token
Automated Authentication Management
Automate authentication operations by combining multiple Sage Accounting API endpoints. Agents can list resources and then get resource in a single workflow.
Call GET /resources to list resources, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Sage Accounting 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 apiKey tokens manually.
Search Jentic for 'get access token', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Sage Accounting API by hand means exchanging its API key for a token at /auth/token, attaching it to each call against api.sage.com, and managing your own retries. Through Jentic you install once, import the Sage Accounting API from the API Directory, store the key once, and your agent calls it.
Permission scoping
Sage Accounting puts the resource id in the URL path (/resources/{id}), so a rule can pin your agent to reading one resource. You choose the operations it may call, so it can list and read resources without any write access unless you add it.
Credential isolation
Your Sage Accounting API 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 'get an access token' or 'read an accounting resource', and Jentic returns the matching Sage Accounting API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Sage Accounting API through Jentic.
What authentication does the Sage Accounting API use?
The Sage Accounting API uses an API key passed in the `X-API-Key` header. 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 get access token with the Sage Accounting API?
Yes. Use the POST /auth/token endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Sage Accounting 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 get access token through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'get access token'. Jentic returns the matching Sage Accounting API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Sage Accounting API have?
The Sage Accounting API exposes 3 endpoints covering authentication, resources operations.
Can I limit what my agent is allowed to do with the Sage Accounting API?
Yes. Because you run Jentic One yourself, your own rules decide which Sage Accounting operations and credentials the agent may use. You can allow it to call GET /resources and GET /resources/{id} to list and read resources while withholding any write access, and since the resource id sits in the URL path you can pin the agent to reading a single resource. The agent can only invoke the operations you have explicitly permitted.
