Sidecar
Sidecar (side.cr) was added to the API Evangelist network as a Union Square Ventures portfolio lead. The side.cr domain today hosts a transportation news and information content platform (self-described as "building the largest transportation news source powered by everyday people"), covering ridesharing, driving, delivery, safety, and automotive topics for riders and drivers. It is a reader-facing editorial site, not a developer platform: as of this enrichment pass it publishes no API, developer portal, documentation, SDKs, OpenAPI, or any /.well-known discovery surface. The name echoes the pioneering peer-to-peer Sidecar ridesharing company that Union Square Ventures backed and that wound down in 2015, but the current content site states no operational or corporate ties to that defunct service. This profile is retained as a company/lead record with no active API surface to enrich.
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 Sidecar 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 — Sidecar scores 9.3/100 (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.

How we profile Sidecar
Each block below is one kind of artifact we hold for Sidecar. 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.
