Install Jentic One Beta

Connect the Line Items to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Line Items, 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.

Capabilities

What an agent can do with Line Items API.

For Agents

Manage HubSpot line item records that represent the priced rows on deals, quotes, invoices, and subscriptions, with batch and search support.

Use for: I need to add three product line items to a HubSpot deal, I want to sync line items from a Stripe subscription into HubSpot, Search for all line items on a quote with quantity over 10, List every line item attached to a specific deal

Not supported: Does not handle product catalog management, payment capture, or tax calculation - use for HubSpot line item record management only.

Use Cases

Patterns agents use Line Items API for, with concrete tasks.

★ Build a Quote with Multiple Products

When a sales rep or agent assembles a quote in HubSpot, each product on the quote is a separate line item record. Using the batch create endpoint, an integration can write all the line items in a single call and link them to the parent quote via the associations array. This pattern keeps the quote consistent with the source product catalogue and avoids per-row API calls.

POST /crm/v3/objects/line_items/batch/create with up to 100 line item records, each carrying an associations entry for the parent quote, and confirm the response status array reports zero errors.

Mirror Stripe Subscription Items into HubSpot

Reflect the line-item composition of a Stripe subscription on the corresponding HubSpot subscription record so the CRM shows the same priced rows the customer is actually being billed for. Batch upsert keyed by an external Stripe item ID handles both create and update in one call, which is the typical pattern for a sync that runs every few minutes off Stripe webhooks.

POST /crm/v3/objects/line_items/batch/upsert with line item records keyed by stripe_item_id, each linked via associations to the HubSpot subscription record.

Agent-Driven Quote Adjustment

An AI agent that drafts or revises quotes can search for the existing line items on a deal, recompute pricing or quantities, and update the records via batch update. Through Jentic, the agent finds the relevant line item operations by intent and chains search and update calls without browsing HubSpot's REST docs.

Search line items via POST /crm/v3/objects/line_items/search filtered by associated deal ID, then POST /crm/v3/objects/line_items/batch/update with new price values reflecting the agent's revised quote.

Why Jentic?

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

Credential isolation

Your HubSpot token 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 line items to a HubSpot quote' or 'search line items', and Jentic returns the matching operation with its input schema, including the associations array shape, so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Line Items API through Jentic.

What authentication does the HubSpot Line Items API use?

OAuth 2.0 Bearer tokens or HubSpot Private App tokens in the Authorization header. Jentic stores the token encrypted in the vault and provides a scoped reference to the agent so the raw token never enters the prompt.

Can I create a line item and link it to a deal in one call?

Yes. POST /crm/v3/objects/line_items accepts an associations array on the request body so the line item is created and linked to a deal, quote, invoice, or subscription in a single call.

What are the rate limits for the HubSpot Line Items API?

Standard HubSpot quotas apply: 100 requests per 10 seconds for OAuth apps and 110 for Private Apps, plus daily caps that vary by Hub tier. Batch endpoints accept up to 100 records per call and count as one request, which is the recommended pattern for high-volume sync jobs.

How do I add multiple line items to a quote through Jentic?

Run pip install jentic, call client.search('add line items to a HubSpot quote'), client.load to get the schema for POST /crm/v3/objects/line_items/batch/create, and client.execute with the line item array - each entry includes properties and an associations array pointing at the parent quote.

Can I search line items by product ID?

Yes. POST /crm/v3/objects/line_items/search accepts filterGroups, including a filter on hs_product_id, so you can find every line item that references a particular product across deals and quotes.

How do I keep line items in sync with an external billing system?

POST /crm/v3/objects/line_items/batch/upsert keyed by a unique external identifier property (such as stripe_item_id) handles both create and update in one call, which is the typical sync pattern when mirroring Stripe or another billing system into HubSpot.

Can I limit what my agent is allowed to do with the HubSpot Line Items API?

Yes. Because Jentic One runs self-hosted on your own instance, your rules decide which line item operations and which HubSpot token the agent may use. You can allow only the operations the agent actually needs, such as searching line items via POST /crm/v3/objects/line_items/search and reading a record at /crm/v3/objects/line_items/{lineItemId}, while withholding batch create, batch upsert, or update paths unless you add them. The agent can then act on the line_items collection within exactly those bounds and nothing more.
