eBay Aftermarket Parts — Price, Brand Tier & Fitment

Search eBay aftermarket auto parts by part name and (optionally) a vehicle, and get price, condition, brand, seller and a hand-authored brand-quality tier — plus real fitment via eBay's own compatibility check. Bring your own free eBay developer key.

What it does

1. Authenticates with OAuth client-credentials using your eBay App ID + Cert ID (Production).
2. Searches the eBay Browse API (item_summary/search), by default inside eBay Motors Parts & Accessories (category 6030).
3. For each listing returns: title, price, currency, condition, brand, seller, seller feedback, buying options, item URL, image, location.
4. Attaches brandTier — OE/Premium, Mid or Budget — from a curated brand map (Bosch/Denso/NGK/Brembo/Bilstein/Aisin/Continental = OE/Premium; Meyle/Monroe/TRW/Sachs = Mid; everything else = Budget). This quality signal is the differentiator; eBay exposes the brand but not its tier.
5. If you pass a vehicle (make/model/year, optional trim/engine), runs eBay's check_compatibility on each listing and sets compatibility to COMPATIBLE / NOT_COMPATIBLE / UNDETERMINED.

You need an eBay key (free)

Create a free application at developer.ebay.com, get your Production keys, and pass:

• clientId — App ID / Client ID (secret)
• clientSecret — Cert ID / Client Secret (secret)

Both are stored as secret inputs. Without them the actor cannot run.

Example inputs

Price scan

{"query":"brake pads","maxResults":50,"clientId":"YOUR_APP_ID","clientSecret":"YOUR_CERT_ID"}

With vehicle fitment

{"query":"brake pads","make":"Honda","model":"Accord","year":"2020","clientId":"YOUR_APP_ID","clientSecret":"YOUR_CERT_ID"}

New only, cheapest first

{"query":"oil filter","filter":"conditions:{NEW}","sort":"price","clientId":"YOUR_APP_ID","clientSecret":"YOUR_CERT_ID"}

Output

Clean JSON, one row per listing — including brandTier and (if a vehicle was given) compatibility.

Important: fitment is a signal, not a guarantee

A COMPATIBLE verdict comes from eBay's compatibility check, which relies on seller-supplied fitment data — it can be missing or wrong. UNDETERMINED means the listing has no fitment catalog. Always verify the exact part number against your vehicle before buying. The brandTier is a convenience heuristic, not an endorsement.

Pricing

Pay per result — $3.00 per 1,000 results. BYO eBay key, so you use your own eBay rate limits; you only pay Apify for the results returned.
