ZeroEntropy
ZeroEntropy builds specialized, lightweight AI models for information retrieval and retrieval-augmented generation (RAG). Its zerank rerankers and zembed embedding models improve the accuracy of any search pipeline, and its hosted retrieval API lets developers create collections, index documents, and run relevance queries (top documents, pages, and snippets) with metadata filtering. The API is a versioned (/v1) HTTP JSON service with US and EU data-center endpoints, official Python and TypeScript SDKs, and API-key bearer authentication. ZeroEntropy is a portfolio company of Initialized Capital operating in the enterprise AI / search sector.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles ZeroEntropy the way a machine reads it — 10 machine-readable artifacts across 7 APIs, 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 — ZeroEntropy scores 49.1/100 (developing), with a separate agent-readiness read of 32/100 (agent aware). 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 ZeroEntropy
Each block below is one kind of artifact we hold for ZeroEntropy. 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.
APIs 7
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Security Posture 3
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.
