LinkAGI Model API

LinkAGI is a Chinese third-party AI API relay (中转站) that fronts a pool of upstream model accounts behind a single host, api.linktoagi.com, and re-exposes them on three imitated vendor protocols: OpenAI-compatible Chat Completions and Responses, an Anthropic Messages-shaped route, and a Gemini generateContent-shaped route. It is sold to developers running Codex, Claude Code, Gemini CLI and desktop chat clients who want a CNY, prepaid, pay-as-you-go base-URL swap instead of a foreign card and a vendor account. A token belongs to a group (号池) that decides which models it can address and at what billing ratio; the live model and price table is published unauthenticated at /api/pricing. The service runs the open-source New API gateway and publishes a first-party OpenAPI 3.1, APIs.json, llms.txt and Postman collection, plus an unusually candid evidence boundary that marks its Anthropic and Gemini compatibility as advertised but unverified.

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 LinkAGI Model API the way a machine reads it — 14 machine-readable artifacts across 5 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 — LinkAGI Model API scores 51.1/100 (developing), with a separate agent-readiness read of 43/100 (agent ready). 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 LinkAGI Model API

Each block below is one kind of artifact we hold for LinkAGI Model API. 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 5

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.

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Security Posture 2

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.

Where this information came from

This is an independent, third-party profile of LinkAGI Model API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
