Baicai
Baicai (白菜二手车, "Baicai Used Cars") is a Chinese used-vehicle trading platform operating a new-retail model that pairs online used-car marketplaces with offline chain "used-car supermarket" stores. Vehicles listed on the platform are inspected by third-party agencies (100+ point checks that exclude major accident, water-damaged, and fire-damaged cars) and carry a return guarantee plus a warranty on major components. The business was spun out of and operates under 58.com (via Tianjin 58 Cloud Car / 天津五八云车) and became independently operated in 2021. It received early seed backing from Ribbit Capital. Baicai is a consumer-facing marketplace and does not publish a public developer platform, API, SDKs, or API documentation; this profile captures its identity and public web presence for the API Evangelist network.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Baicai the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Baicai scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Each block below is one kind of artifact we hold for Baicai. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
