How the price column is worked out. One search returning 50 sales, one request per search, at each product's published prices. eBay Finding API (findCompletedItems): Retired; no price. eBay Browse API: The Browse API returns items for sale, not sold prices, so a price per sold-data search doesn't apply. eBay Marketplace Insights API: Marketplace Insights is not open to new users, so there is no price to compute. SoldComps.io: A 50-sale search costs 20 + 50 × 1 = 70 credits; Starter: 50,000 credits ÷ 70 = 714 searches for $5, so $7.00 per 1,000 searches; Growth: 300,000 credits ÷ 70 = 4,285 searches for $29, so $6.77 per 1,000 searches; Scale: 850,000 credits ÷ 70 = 12,142 searches for $79, so $6.51 per 1,000 searches; Pay as you go: 50,000 credits ÷ 70 = 714 searches for $6, so $8.40 per 1,000 searches; Fewer sales cost less: a 20-sale search is 40 credits, $4.00 per 1,000 on Starter. sold-comps.com: Starter: $9 ÷ 2,000 requests × 1,000 = $4.50; Growth: $29 ÷ 10,000 requests × 1,000 = $2.90; Scale: $79 ÷ 50,000 requests × 1,000 = $1.58; high-volume plans as listed: $1.29 at 100,000 down to $0.499 at 2,000,000; credits: $3 per 1,000 requests CompSniper: Starter: $9 ÷ 2,000 requests × 1,000 = $4.50; Growth: $29 ÷ 10,000 requests × 1,000 = $2.90; Scale: $79 ÷ 50,000 requests × 1,000 = $1.58; 500K: $549 ÷ 500,000 requests × 1,000 = $1.10; credits: $5.00 per 1,000 requests CompsAPI: Starter: $9 ÷ 5,000 requests × 1,000 = $1.80; Growth: $29 ÷ 25,000 requests × 1,000 = $1.16; Pro: $79 ÷ 100,000 requests × 1,000 = $0.79; annual billing lists Starter at $7.50/mo, so lower still Soldgraph: Lite: $9 ÷ 2,000 requests × 1,000 = $4.50; Starter: $19 ÷ 5,000 requests × 1,000 = $3.80; Pro: $49 ÷ 20,000 requests × 1,000 = $2.45; Business: $149 ÷ 100,000 requests × 1,000 = $1.49; pay as you go: $10 per 1,000 with no plan, $3 per 1,000 on any paid plan

Where eBay's own APIs are better

• eBay's Browse API is open to developers and is the right tool for active listings: if you don't need sold prices, use it.
• Marketplace Insights is eBay's own sold-data API, if you are one of the approved developers.

Where SoldComps.io is different

• SoldComps.io maps closely to a findCompletedItems keyword search: one GET with q, condition, price range, buying format and days, returning sold items with price, date, condition, shipping and link.
• SoldComps.io returns the median and middle half (p25 to p75) with lots, for-parts units, replicas, accessories and outliers flagged and left out of the stats.
• SoldComps.io has a remote MCP server at https://www.soldcomps.io/mcp that Claude, ChatGPT and Cursor can use with no key; add a Bearer key to bill your own credits.
• Errors are never billed, and every response reports what it cost.

When to pick which

• Use the Browse API for active listings only.
• Pick SoldComps.io for a drop-in sold search on eBay US, UK or Germany with the median worked out, or for AI agents through MCP.
• Pick sold-comps.com or Soldgraph for more eBay sites and other marketplaces.
• Pick CompsAPI or CompSniper for sold history beyond 90 days or accepted Best Offer prices.
