Back Market

Back Market is a French-founded global online marketplace dedicated exclusively to refurbished consumer electronics — smartphones, laptops, tablets, consoles, watches, audio and home appliances — operating across 17 countries on three regional platforms (EU via backmarket.fr, North America via backmarket.com, Asia-Pacific via backmarket.co.jp). For the ~1,800 professional refurbishers selling on the platform, Back Market publishes a seller-facing REST API (the "Back Market API Guidelines") covering the marketplace taxonomy, product and listing management, order and orderline workflows, BuyBack (trade-in) orders and listings, Backship deliveries and returns, the Care after-sales platform (claims, messages, refunds, item transfers), and Backbox competitive pricing data. The API is documented as an OpenAPI 3.0.3 contract rendered with Stoplight Elements at api.backmarket.dev, authenticated with a Basic token issued from the seller Back Office, and mirrored by preprod environments on every regional platform.

Back Market publishes 9 API contracts indexed on the APIs.io network, including Backbox API, Backship API, Care API, and 6 more. Tagged areas include Company, E-Commerce, Marketplace, Retail, and Refurbished Electronics.

The Back Market catalog on APIs.io includes 1 Spectral governance ruleset.

Back Market’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 33 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Carbon Markets and Environmental Services (carbon removal, waste, mining)	undeclared	-	-	-
Electronics Recycling & Circular Economy (e-waste, battery value chain, circularity networks)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
