Cinder

Cinder is a Trust & Safety platform — an operating system for online Trust & Safety and content moderation teams. It unifies policy management, content review and moderation queues, investigations, automated detection, and reporting into a single workflow so platforms can enforce their rules consistently and at scale. The company (originally at cinder.co, now cinder.ai) was founded by operators with backgrounds at Meta, Palantir, and US national-security teams, and applies AI and agentic automation to content classification, case management, and enforcement. Cinder is venture-backed (Accel, and additional investors) and sits in the security / trust & safety sector. This API Evangelist profile was surfaced as a portfolio company and enriched by the pipeline; the company's public surface is behind bot protection, so API artifacts remain to be confirmed.

human only

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.

Kin Score

API Evangelist profiles Cinder 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 — Cinder 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.

How we profile Cinder

Each block below is one kind of artifact we hold for Cinder. 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.
