For Agents

Download bulk eBay item feed files (full and hourly snapshots) by category and marketplace for offline catalogue ingestion. Limited Release access only.

Install Jentic One Beta

Connect the Item Feed Service to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Item Feed Service, 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 Item Feed Service API.

Download a full TSV_GZIP item feed for a category and marketplace on a given date

Pull an hourly snapshot of items that changed within the last hour for a category

Retrieve item-group feed files to capture variation-level listings in bulk

Use Cases

Patterns agents use Item Feed Service API for, with concrete tasks.

★ Bulk catalogue ingestion for a price-monitoring agent

Approved partners use the Item Feed Service to download daily full-category TSV_GZIP files instead of paginating through Browse search. A monitoring agent can ingest tens of millions of listings per day per marketplace, then run hourly snapshot files to keep its mirror current. The Feed SDK handles chunked download, resume on failure, and field-level filtering so the agent only stores the columns it needs.

Download today's full item feed for category 9355 on EBAY_US, then pull the hourly snapshot file produced in the last hour and merge changed item IDs into the local mirror

Variation-aware product reconciliation

The /item_group endpoint returns feed files of items with variations (size, colour, configuration) grouped by parent listing. Resellers and aggregators reconcile their internal SKUs against eBay variation IDs without writing per-item Browse calls. One feed file replaces tens of thousands of /item/get_items_by_item_group requests from the Browse API.

Download the item_group feed for category 11450 on EBAY_GB and emit a CSV of parent-listing-ID to variation-ID mappings

Promoted listings and priority inventory tracking

The /item_priority resource exposes feeds of items flagged as priority by eBay (promoted or business-managed inventory subsets). Affiliate networks and demand-side platforms ingest these feeds to keep their ad inventory aligned with what eBay is actively pushing, with new files published on the standard daily cadence.

Pull the latest /item_priority feed for EBAY_US and write the item IDs to a downstream advertising bid table

AI agent integration via Jentic

An AI agent that monitors eBay catalogue movements queries Jentic for 'download bulk eBay item feed' and Jentic returns the Item Feed Service /item operation with its required parameters (category_id, date, marketplace). The agent loads the schema, executes the call with a partner OAuth token issued through Jentic's vault, and streams the TSV_GZIP file to local storage — without storing the OAuth secret in agent memory.

Use Jentic to search 'download bulk eBay item feed', load the /item operation schema, and execute it for category 9355 on EBAY_US for today's date

Key Endpoints

4 endpoints — the ebay item feed service lets approved buy api partners download bulk tsv_gzip feed files of ebay items by category, marketplace, and date, plus hourly snapshot files of items that have changed within the last hour.

Why Jentic?

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

Credential isolation

eBay OAuth 2.0 client credentials are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens for the buy.item.feed scope only — the raw client secret never enters the agent's context.

Intent-based discovery

Agents search by intent (e.g., 'download bulk eBay item feed') and Jentic returns the matching /item or /item_snapshot operation with its required parameters (category_id, date, marketplace_id), so the agent can call the right endpoint without browsing eBay's docs.

Time to first call

Direct integration: 3-7 days for OAuth client-credentials flow, partner approval handling, and TSV_GZIP streaming logic. Through Jentic: under 1 hour — search, load schema, execute.

FAQs

Specific to using Item Feed Service API through Jentic.

What authentication does the Item Feed Service use?

The Item Feed Service uses OAuth 2.0 with the Client_Credentials grant. Partners obtain an Application access token scoped to https://api.ebay.com/oauth/api_scope/buy.item.feed and pass it as a Bearer token. Through Jentic, the OAuth client secret is held in the MAXsystem vault and the agent receives a scoped access token only — the raw secret never enters agent context.

Can I download the entire eBay catalogue with the Item Feed Service?

You can download per-category daily full feeds (/item) plus hourly snapshot files (/item_snapshot), but only for categories and marketplaces your partner application has been approved for. There is no single endpoint that returns every listing on eBay — feeds are partitioned by category_id, date, and marketplace_id (e.g. EBAY_US).

What are the rate limits for the Item Feed Service?

Feed downloads are governed by eBay's Buy APIs rate limits, which are issued per application and per partner agreement rather than as a fixed public quota. Daily call counts are visible through the Developer Analytics API. Because each download can be multi-gigabyte, the practical bottleneck is bandwidth and HTTP Range chunking, not call count.

How do I download an item snapshot file through Jentic?

Search Jentic for 'download eBay item snapshot', load the /item_snapshot operation schema, and execute it with category_id, snapshot_date (ISO 8601 hour), and marketplace_id. Install with pip install jentic and call client.search, client.load, then client.execute. Sign up at https://app.jentic.com/sign-up.

Is the Item Feed Service free?

The API itself has no per-call charge, but it is a Limited Release service — you must be approved by an eBay business unit before production access is granted. Apply through the Buy APIs Requirements page on developer.ebay.com.

What format are the feed files returned in?

Feed files are returned as TSV_GZIP — tab-separated values, gzip-compressed. The open-source eBay Feed SDK (Java) handles chunked download, decompression, and field-level filtering, and is the recommended client for production ingestion.
