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.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles RouterPlex the way a machine reads it — 17 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 — RouterPlex scores 58.1/100 (strong), with a separate agent-readiness read of 49/100 (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 RouterPlex
Each block below is one kind of artifact we hold for RouterPlex. 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.
RouterPlex Chat API
The Chat API from RouterPlex — 1 operation(s) for chat.
RouterPlex Images API
The Images API from RouterPlex — 1 operation(s) for images.
RouterPlex Messages API
The Messages API from RouterPlex — 1 operation(s) for messages.
RouterPlex Models API
The Models API from RouterPlex — 1 operation(s) for models.
RouterPlex Responses API
The Responses API from RouterPlex — 1 operation(s) for responses.
Open Collections 6
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

OPEN COLLECTIONMCP 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.

MCP SERVERPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Routerplex Plans
PLANSRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Routerplex Rate Limits
RATE LIMITSSecurity 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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of RouterPlex, 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.
