View OpenAPI Document

The eBay Deal API is a Limited Release member of the eBay Buy API family that exposes promotional deals and time-bound events along with the eligible items inside each. The four-endpoint surface lets approved partners list current deal items, retrieve event metadata, list active events, and fetch the items associated with a given event. It is used by deal aggregators, browser extensions, and AI shopping agents that need authoritative access to eBay's curated deal inventory rather than scraping the public site.

Use Cases

Patterns agents use Deal API API for, with concrete tasks.

★ Deal aggregator content feed

Deal sites and browser extensions need a daily refresh of eBay's curated promotions. An agent calls /event to list active events, then /event_item to expand each into its eligible inventory, generating a structured feed without scraping the eBay website. Each call is paginated so the feed can be ingested incrementally.

List the first ten active eBay deal events and return their event IDs and start dates.

Personalised savings recommendations

A shopping agent that knows a user's category preferences can call /deal_item filtered by category to surface the best matching deals. The structured response means the agent can rank by discount or price and present a tailored list rather than redirecting the user to eBay's deals page.

Fetch the top deal items in the electronics category and return the three with the largest percentage discount.

Event-driven savings campaigns

Affiliate marketers running newsletter campaigns can pull all items eligible for a known event ID and embed selections in their send. /event_item returns the eligible inventory for a specific event so the campaign content stays in sync with eBay's promotional calendar.

Given event ID 'CYBER_MONDAY_2026', list the first 50 eligible items and return their item IDs and titles.

Agent-driven deal discovery

Through Jentic, a shopping assistant interprets natural-language requests like 'find eBay deals on cameras under 500 dollars' and resolves them into the right combination of /deal_item and /event calls. The agent does not need to manage OAuth tokens or parse the Limited Release access conditions — Jentic handles both.

Given a user request for camera deals, call /deal_item with the appropriate category filter and return the best three matches.

Why though 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). Jentic exchanges them for application access tokens, caches the token, and injects it into the Authorization header. Raw client secrets never reach the agent.

Intent-based discovery

Agents search Jentic for intents like 'list ebay deals' and Jentic returns the matching Deal API operation with its input schema, so the agent does not need to navigate the eBay developer portal or the Buy API family hierarchy.

Time to first call

Direct eBay Deal API integration: 3-5 days including OAuth client setup, business-unit approval coordination, and per-endpoint payload handling. Through Jentic: under 1 hour once approval is in place — search, load schema, execute.

FAQs

Specific to using Deal API API through Jentic.

What authentication does the eBay Deal API use?

The Deal API uses OAuth 2.0 application access tokens via the eBay api_auth scheme. The Deal API is a Limited Release that requires business-unit approval before tokens will succeed. Through Jentic, the OAuth client credentials are stored encrypted in the vault and the token exchange is handled at execution time.

Can I list all current eBay deal events with the Deal API?

Yes. GET /event returns the list of active deal events, and GET /event/{event_id} returns the metadata for a specific event. Pair this with GET /event_item to expand any event into its eligible inventory.

What are the rate limits for the eBay Deal API?

The Deal API inherits the eBay Buy API rate-limit framework, which is plan-dependent and visible in the eBay developer dashboard once the Limited Release approval is in place. Standard application tokens see daily call caps — confirm your specific limits in the Application Growth Check section of your developer account.

How do I retrieve eligible deal items through Jentic?

Search Jentic for 'list ebay deal items', load the schema for GET /deal_item, then execute. The flow is: pip install jentic, then await client.search, await client.load, await client.execute. Jentic injects the OAuth token from the cached credential exchange.

Is the eBay Deal API free to use?

Access to the Deal API itself is free for approved developers, but it is a Limited Release that requires eBay business-unit approval before production use. See the Buy APIs Requirements page on the eBay developer portal for the application criteria.

Can I create or modify deal events with the Deal API?

No. The Deal API is read-only — its four endpoints expose deal items, events, and event-item lists. Creating or scheduling promotional events is handled inside eBay's seller and merchandising tooling, not via this API.
