Countdown API
Buyers want product comparisons, review summaries, and seller reputation checks before purchasing. Your AI agent queries Countdown API to search eBay listings, pull real-time pricing, and surface customer reviews, all within a single conversation. Data-driven purchase decisions happen instantly.
Your AI agent leverages Countdown API's full eBay data pipeline to search products, batch requests, and deliver structured marketplace insights mid-conversation.
Countdown API
Discover how e-commerce teams and resellers use AI agents to pull live eBay marketplace data, schedule monitoring, and surface actionable product intelligence.
A reseller asks 'What is the current going rate for a PS5 on eBay UK?' Your AI Agent sends a search request through Countdown API targeting ebay.co.uk, retrieves active listings with current bid and buy-it-now prices, and returns a price range summary. The reseller makes sourcing decisions instantly without manually browsing eBay or running separate scraping tools.
An e-commerce manager needs daily snapshots of competitor pricing on 500 eBay SKUs. Your AI Agent creates a Countdown API collection, adds all product requests, sets a daily schedule, and configures webhook notifications. Every morning the team receives fresh eBay data in their preferred format. Competitive intelligence runs on autopilot without engineering resources.
A procurement team evaluates whether to add a new product category. Your AI Agent queues 2,000 eBay product lookups into a collection, starts processing, and retrieves the result set once complete. The team downloads structured data on pricing, review counts, and seller density to make a data-backed expansion decision without weeks of manual research.

FAQs
The agent can fetch product details, search results, customer reviews, seller feedback, and autocomplete suggestions. Data is retrieved from any of the 20 supported eBay domains worldwide. Product lookups support GTIN, ISBN, UPC, and EAN identifiers. All data is returned as structured JSON from Countdown API's parsing engine.
Collections let you queue up to 15,000 eBay data requests and run them on a schedule. The agent creates a collection, adds request parameters for each product or search query, sets the run frequency (hourly, daily, weekly, or monthly), and starts processing. Results are retained for 14 days and can be downloaded as JSON, CSV, or JSON Lines.
Yes. Countdown API supports 20 eBay domains including ebay.com, ebay.co.uk, ebay.de, ebay.fr, and others. The agent specifies the ebay_domain parameter per request, so you can compare pricing and availability across different regional eBay marketplaces within a single conversation.
No. Tars queries Countdown API in real-time and passes results directly to the conversation. Collection result sets are stored by Countdown API for 14 days on their infrastructure. Tars acts as a pass-through and does not maintain a separate database of your scraped eBay data.
The agent checks collection status before starting. If a collection is already processing, the agent reports its current state and can queue a new collection separately. You can also use the Stop Collection endpoint to pause a running job before starting a fresh run.
Yes. Countdown API supports destinations including AWS S3, Google Cloud Storage, Azure Blob Storage, and Alibaba OSS. The agent creates a destination with your cloud credentials, attaches it to a collection, and results upload automatically after each run. No manual downloads required.
Building your own eBay scraper means handling bot detection, CAPTCHAs, IP blocking, and layout changes. Countdown API renders pages in a full browser engine with proprietary parsing that adapts to eBay's structure automatically. Your AI agent simply sends a request and gets clean, structured data back without any scraping infrastructure.
Yes. If a webhook delivery fails or you need to reprocess results, the agent calls the Resend Result Set Webhook endpoint with the collection and result set IDs. Countdown API retriggers the POST to your configured webhook URL so your downstream systems receive the data without rerunning the entire collection.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
