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.

LinkAGI Model API publishes 5 APIs on the APIs.io network, including Anthropic-style route API, Discovery API, Gemini-style route API, and 2 more. Tagged areas include Artificial Intelligence, LLM, AI API Gateway, Relay, and OpenAI-Compatible.

LinkAGI Model API’s developer surface includes authentication, documentation, getting-started guide, support, engineering blog, GitHub presence, pricing, and 20 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/linkagi-model-api: open an issue to ask a question, or submit a pull request to add artifacts.
