Install Jentic One Beta

Connect the Recommendation API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Recommendation 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://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.

Use Cases

Patterns agents use Recommendation API for, with concrete tasks.

★ Smart Promoted Listings Campaign Building

Rather than promoting every active listing, sellers can call POST /find with their listingIds and receive eBay's recommendation on which would benefit from being promoted. The response includes suggested ad-rate strategies so the seller can start a campaign with eBay-informed bids. This typically improves ROAS because budget concentrates on listings with predicted lift.

POST /find with the seller's top 100 active listingIds and read the recommendation response to choose which to promote.

Periodic Ad-Rate Strategy Refresh

Marketplace dynamics shift, so the recommended ad-rate for a listing changes over time. Sellers schedule a recurring job that calls POST /find on their full active inventory to refresh the suggested ad-rates and update the corresponding Promoted Listings ads via the Marketing API. The combined flow keeps bids aligned with eBay's current recommendations.

Run POST /find weekly across active listings, compare the recommended ad-rates with current bids, and update bids via the Marketing API where the recommendation has changed.

Decision Support for Manual Sellers

Smaller sellers who manage campaigns by hand can use a one-shot recommendation pull to decide where to put their first ad budget. The Recommendation API exposes which listings eBay's models predict will respond to paid promotion and the recommended starting bid, so a seller without paid-search experience has a sensible baseline.

Call POST /find with all of the seller's active listingIds and present the top 10 recommendations to the seller as a starting Promoted Listings shortlist.

AI Agent Promoted Listings Curator

An AI agent integrated with a seller's commerce platform can use Jentic to discover the Recommendation API, pull recommendations, and orchestrate Promoted Listings creation through the Marketing API in a single workflow. The agent uses recommendations as the input to a campaign-launch step and can re-evaluate weekly without seller intervention.

Through Jentic, search 'get ebay promoted listings recommendations', load the POST /find schema, and execute it to build a Promoted Listings campaign from the recommended listings.

Why Jentic?

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

Credential isolation

Your eBay OAuth seller credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'get eBay Promoted Listings recommendations', and Jentic returns the POST /find operation with its input schema for listing ids and filters so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Recommendation API through Jentic.

What authentication does the eBay Recommendation API use?

The eBay Recommendation API uses OAuth 2.0 (the api_auth scheme) with seller-scoped tokens. Through Jentic, the OAuth client credentials are stored encrypted in your Jentic One instance and the agent receives only short-lived scoped access tokens at call time.

Can I get Promoted Listings recommendations for my eBay inventory?

Yes. POST /find accepts an array of listingIds and returns eBay's recommendation on which to promote, along with the suggested ad-rate strategy for each recommended listing.

What are the rate limits for the eBay Recommendation API?

The Recommendation API shares the eBay Sell API call quota tied to the seller's Application Growth Check tier rather than per-endpoint limits in the spec. Batching listingIds in a single POST /find keeps call volume low at scale.

How do I get Promoted Listings recommendations through Jentic?

Search 'get ebay promoted listings recommendations' in Jentic, load the POST /find schema, pass an array of listingIds, and Jentic executes the call. The response identifies which listings to promote and at what ad-rate.

Does the eBay Recommendation API give recommendations for non-Promoted-Listings actions?

No. Today the spec exposes only Promoted Listings recommendations through the find endpoint. Other recommendation types are not part of this API surface.

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

Yes. Because you run Jentic One self-hosted, your own rules decide which operations and credentials the agent may use. This API exposes a single endpoint, POST /find, so you scope the agent to requesting Promoted Listings recommendations for only the listing ids and filters you allow it to pass. That operation returns suggested ad-rate strategies and cannot create or run campaigns, so the agent stays read-only against your eBay seller account.
