How the price column is worked out. One search returning 50 sales, one request per search, at each product's published prices. 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. 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 Soldgraph is better

• Far more marketplaces: eBay in 8 countries, Poshmark and Mercari sold data, and active listings from Depop, Whatnot, OfferUp, Facebook Marketplace and Vinted.
• Cheaper per search on paid plans: $4.50 per 1,000 on Lite down to $1.49 on Business, and $3 per 1,000 extra on a paid plan.
• Batches: up to 100 searches in one call on Business (10 on Free), with every row downloadable as one CSV.
• Up to 200 rows a request at one price.

Where SoldComps.io is different

• 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. Soldgraph's median, low and high are plain maths over the page, with no rows removed.
• 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.
• A free tier that refills: 2,000 credits a month. Soldgraph's 100 free requests don't refill.
• Synchronous: one GET returns the answer. Soldgraph often returns 202 and a job to poll.

When to pick which

• Pick Soldgraph if you need Poshmark, Mercari, Vinted or local-marketplace data, batch CSV exports, or the lowest price per search.
• Pick SoldComps.io if you want a cleaned eBay median in one synchronous call, a free tier that refills each month, or an MCP server that works without a key.
