GPTZZZ

GPTZZZ (gptzzz.ai, subtitle "AI API 中转服务 中转站") is an independent third-party AI API relay (中转站) and multi-model gateway for Chinese-speaking developers. It exposes an OpenAI-compatible interface at https://gptzzz.ai/v1 (chat completions, Responses, embeddings, images), a Claude Messages route at https://gptzzz.ai/v1/messages and a Gemini-style v1beta surface, authenticated with a GPTZZZ API key via Authorization Bearer, x-api-key or x-goog-api-key. Public prices are listed at https://gptzzz.ai/pricing/ (48 models from 7 vendors in 10 billing groups, also served as JSON at /api/v1/model-plaza), billed from a prepaid balance (a ¥1 top-up gives $1 of balance); each API key belongs to one billing group. It also ships a desktop client (macOS, Windows x64 and ARM64) that adds GPTZZZ as a provider in Claude Code, Codex, 小龙虾, 爱马仕 and Grok, and a Chinese knowledge base on relay selection, security and compliance. The same team runs kaigpt.ai, a separate product with separate billing. GPTZZZ states it is not affiliated with the model vendors it routes to; it resells access to other providers' model APIs rather than training models itself.

GPTZZZ is listed with 2 APIs on the APIs.io network. Tagged areas include Artificial Intelligence, LLM Gateway, API Relay, OpenAI-Compatible, and Claude.

GPTZZZ’s developer surface includes pricing, authentication, documentation, getting-started guide, support, engineering blog, signup flow, and 13 more developer resources.

scored 2026-11-02 · rubric v0.26.0
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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
  • Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
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 the provider profile at artifacts.apis.io/gptzzz/apis.yml: open an issue on github.com/api-evangelist/gptzzz to ask a question or point us at an artifact you publish.
