eBay Aftermarket Parts — Price, Brand Tier & Fitment

Search eBay aftermarket auto parts by part and vehicle, and get price, condition, brand, seller — plus two things nobody else surfaces: a hand-authored brand-quality tier (OE/Premium / Mid / Budget) and real fitment via eBay's own compatibility check. Bring your own free eBay developer key.

For parts resellers, repricing tools, garages and auto lead-gen.

What you get

Per listing:

• Listing — itemId, title, price, currency, condition, conditionId, buyingOptions[], itemUrl, image, itemLocation
• Seller — seller, sellerFeedbackPct, sellerFeedbackScore
• Brand + tier — brand from eBay's aspect, and brandTier = OE/Premium, Mid or Budget from a curated brand map (the differentiator)
• Fitment (when a vehicle is passed) — compatibility = COMPATIBLE / NOT_COMPATIBLE / UNDETERMINED, plus compatibilityNote

Bring your own key (free, required)

Create a free application at developer.ebay.com, get your Production keys, and pass clientId (App ID) and clientSecret (Cert ID) — both stored as secret inputs. The actor authenticates via OAuth client-credentials. Without both keys the actor exits cleanly with no results (it uses your own eBay rate limits, keeping cost low).

Why this actor

• brandTier — a quality signal nobody else has — eBay exposes the brand but not whether it's OE/Premium, Mid or Budget; this actor attaches it from a hand-curated map.
• Real fitment — eBay's own check_compatibility per listing, not a guess.
• BYO-key — you get your own eBay quota; you only pay Apify for the rows returned.

Pricing

Pay per result — $3.00 per 1,000 results (one result = one listing row). BYO eBay key means you use your own eBay rate limits; you only pay Apify for the results returned.

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. Prices change constantly; not affiliated with eBay.
