RouterPlex

RouterPlex is an OpenAI- and Anthropic-compatible AI gateway that fronts 39 chat and image models from 14 vendors — OpenAI, Anthropic, Google, DeepSeek, Moonshot, Alibaba, MiniMax, Zhipu, xAI and others — behind one API key and one prepaid balance, at vendor list prices with no markup and no top-up fee. It exposes OpenAI Chat Completions, the OpenAI Responses route for Codex, Anthropic Messages, image generation and a model catalog on a single v1 REST surface, so the official OpenAI and Anthropic SDKs work unmodified with only a base URL change. Per-key hard spend budgets, model allowlists and optional RPM/TPM limits are the containment model for autonomous agents. RouterPlex also runs an anonymous read-only MCP server for model discovery and publishes an RFC 9727 API catalog, an OpenAPI 3.1 description, llms.txt and Markdown pricing and benchmark companions.

RouterPlex publishes 5 APIs on the APIs.io network, including Chat API, Images API, Messages API, and 2 more. Tagged areas include LLM, Artificial Intelligence, AI Gateway, Inference, and Model Router.

RouterPlex’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 30 more developer resources.

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.

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/routerplex: open an issue to ask a question, or submit a pull request to add artifacts.
