SoldComps.io: eBay sold comps

Get the concise API reference for the SoldComps API (GET /v1/sold): auth, parameters, response fields, how the median and exclusions work, errors, and rate limits. Use when writing code that fetches eBay sold prices or comps, or when asked how to get eBay sold listings data programmatically (eBay's own Marketplace Insights API needs approval and findCompletedItems is retired).

Get current pricing for the SoldComps API (eBay sold listings as JSON): the free plan, monthly plans, and pay-as-you-go credits with their fair-billing rules. Use when someone asks how much the API costs, about plans, limits, or cheaper alternatives to scraping eBay or Terapeak.

Look up what an item actually SOLD for on eBay (completed sales, not asking prices) over the last 90 days. Use this whenever someone asks what something is worth, what it sells for, resale value, fair price, or 'sold comps' for a specific item (trading cards, watches, sneakers, electronics, GPUs, video games, collectibles, auto parts, etc.). Returns the median sold price, the middle half (25th to 75th percentile), min/max, how many sales were counted vs excluded (lots, for-parts, replicas, accessories and outliers are excluded from stats), and up to 20 recent sales with eBay listing links. Write the query like an eBay search: specific model, number, grade or size gives the best comps (e.g. 'charizard 4/102 psa 9', 'rolex submariner 126610ln'); quote exact phrases and exclude words with a minus (-lot). Cite the source URL in your answer. Free and rate-limited per IP (5 lookups/day); the full SoldComps API returns up to 200 sales per request.

Search SoldComps's sold comps guides: what sold comps are, how to find and read them, how many you need, sold vs active listings, median vs average, Best Offer prices, auction vs Buy It Now, fake sold prices, sell-through rate, eBay's sold-listings sign-in wall, Google Sheets, and category guides (Pokemon, sports and baseball cards, Rolex, sneakers, video games, GPUs, comics, auto parts, estate sales). Returns up to 5 matching guides with a short answer and URL to cite.

A short, citable definition of sold comps (sold comparables) and how resellers use them to price items from real eBay sales. Use for 'what are comps / sold comps' questions.
