Programmatically adds a fixed asset, searches fixed asset. Covers 6 operations with oauth2 authentication.
Use for: I need to adds a fixed asset, I want to searches fixed asset, Search for retrieves fixed asset by id, Find all adds a fixed asset type
Not supported: Does not handle payments, communications, or crm - use for finance and accounting only.
The Assets API exposes fixed asset related functions of the Xero Accounting application and can be used for a variety of purposes such as creating assets, retrieving asset valuations etc. The API exposes 6 endpoints secured with oauth2 authentication.
Install Jentic One Beta
Connect the Xero Assets API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Xero Assets 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%2Fxero.com%2Fxero-assets-api" | 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%2Fxero.com%2Fxero-assets-api" | 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 Xero Assets API.
adds a fixed asset
searches fixed asset
Retrieves fixed asset by id
Query and filter Xero Assets API records by parameters
Monitor Xero Assets API operational status and events
Use Cases
Patterns agents use Xero Assets API for, with concrete tasks.
★ Finance and Accounting Operations
Use the Xero Assets API to perform finance operations programmatically. The API provides 6 endpoints covering core functionality including adds a fixed asset, searches fixed asset, retrieves fixed asset by id.
Call POST /Assets to adds a fixed asset
Automated Assettypes Management
Automate assettypes operations by combining multiple Xero Assets API endpoints. Agents can searches fixed asset and then retrieves fixed asset by id in a single workflow.
Call GET /Assets to searches fixed asset, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Xero Assets 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 'adds a fixed asset', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Xero Assets API by hand means implementing its OAuth2 flow, sending the tenant header, and handling fixed assets and asset types yourself. Through Jentic you install once, import the Xero Assets API from the API Directory, store the OAuth2 credential once, and your agent calls it.
Permission scoping
The Xero Assets API puts the asset id in the URL path (/Assets/{id}), so a rule can pin your agent to one asset. You choose the operations it may call, so writes like adding a fixed asset or an asset type are not included unless you add them, and reads such as fetching settings can stand alone.
Credential isolation
Your Xero Assets API OAuth2 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 'add a fixed asset' or 'list asset types', and Jentic returns the matching Xero Assets API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Xero Assets API through Jentic.
What authentication does the Xero Assets API use?
The Xero Assets 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 adds a fixed asset with the Xero Assets API?
Yes. Use the POST /Assets endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Xero Assets 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 adds a fixed asset through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'adds a fixed asset'. Jentic returns the matching Xero Assets API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Xero Assets API have?
The Xero Assets API exposes 6 endpoints covering assettypes, assets, settings operations.
Can I limit what my agent is allowed to do with the Xero Assets API?
Yes. Jentic One is self-hosted by you, so your own rules decide which Xero Assets API operations and credentials the agent may use. You can grant read-only access, such as searching fixed assets or fetching settings, while withholding writes like adding a fixed asset or an asset type unless you explicitly allow them. Because the asset id sits in the URL path at /Assets/{id}, you can also pin the agent to a single asset. Credentials are injected at execution time under these limits, never exposed to the agent.
