Mercari US product data API

The ShopAPIS Mercari US product data API returns listing price, item condition, brand, size, seller info, photos and sold/active status for any mercari.com listing — as clean JSON in USD. Mercari is a general C2C resale marketplace where asking prices and sold listings are the core signal, and parsing is the only way to track that long-tail used-goods pricing at scale.

Mercari US is a major consumer-to-consumer marketplace with ~100 million monthly visits to its .com domain (SEMrush 2025, global estimate). Its catalog is fragmented, listing-level used inventory across apparel, electronics, toys and collectibles — high in volume, weaker in structure than a 1P catalog, and valuable for resale and recommerce pricing.

Why Mercari US data is hard to get

Mercari’s only legacy API is limited and not an open catalog source, and listings are unstructured C2C inventory where condition, brand and size are buried in free-text fields. Pages are protected by a medium bot-scoring stack, and asking prices are far noisier than sold prices as a market signal — so distinguishing active from sold listings matters. ShopAPIS parses the listing detail, extracts condition and brand from semi-structured fields, and flags sold status so you can build a reliable resale price picture.

Data fields returned

• Identifiers — Mercari listing ID, brand, inferred model where present.
• Pricing — asking price, currency, original price if shown, shipping cost.
• Condition — new / like-new / good / fair, seller-stated.
• Status — active vs sold/completed listing.
• Attributes — brand, size, color, category, free-text description highlights.
• Seller — seller name, rating, number of sales.
• Media — listing photo gallery.
• Shipping — who pays, estimated delivery, ship-from region.
