Kimi (Moonshot AI)
Moonshot AI (moonshot.ai) is a Chinese foundation model company whose stated mission is "to seek the optimal conversion from energy to intelligence", best known for Kimi, a family of large language models with long-context capabilities (Kimi K3.1 Pro advertises a 1M-token context window) and the consumer Kimi assistant at kimi.com. The Kimi API Platform (platform.kimi.ai, formerly platform.moonshot.ai; platform.kimi.com in China) exposes OpenAI-compatible chat completion, Anthropic Messages-compatible, files, batch, models, balance, and token-estimation APIs, and the company publishes open-weight Kimi models on GitHub.
Reference-quality API operations across every facet — a rich contract, published governance, transparent operations, and machine-readable commercial terms.
API Evangelist profiles Kimi (Moonshot AI) the way a machine reads it — 51 machine-readable artifacts across 2 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 — Kimi (Moonshot AI) scores 66.9/100 (exemplar), with a separate agent-readiness read of 35/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.
Put this on your own site. The badge is drawn live from Kimi (Moonshot AI)'s current Kin Score — paste it once and it updates itself every time the score is recomputed. It follows your visitor's light or dark setting, and it links back here so anyone who sees it can read the full breakdown.

How we profile Kimi (Moonshot AI)
Each block below is one kind of artifact we hold for Kimi (Moonshot AI). 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 14
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.
Moonshot AI Batch API
The Batch API from Moonshot AI — 4 operation(s) for batch.
Moonshot AI Billing API
The Billing API from Moonshot AI — 1 operation(s) for billing.
Moonshot AI Files API
The Files API from Moonshot AI — 3 operation(s) for files.
Moonshot AI Models API
The Models API from Moonshot AI — 1 operation(s) for models.
Moonshot AI Utilities API
The Utilities API from Moonshot AI — 2 operation(s) for utilities.
Kimi Embeddings API
OpenAI-compatible embeddings endpoint that returns vector representations of input text for semantic search, clustering, and retrieval-augmented generation workflows.
Kimi Fine-Tuning API
Fine-tuning jobs endpoint for customizing Moonshot base models on customer-supplied training data. Mirrors the OpenAI fine-tuning surface.
Kimi Tokenizer API
Helper endpoint exposed by the Moonshot platform for counting tokens against a given model's tokenizer prior to submission, useful for managing long-context budgets.
Kimi Assistant (kimi.com)
Consumer-facing AI assistant at kimi.com (also kimi.ai) powered by the Kimi models. Supports long-document upload, web search grounding, and tool use through a chat UI.
Moonshot Open-Weights Releases
Open-weight Kimi model releases (for example prior Kimi K1 / K2 checkpoints) published under the MoonshotAI GitHub organization for research and self-hosted use.
Moonshot AI Responses API
POST /v1/responses — "Create a model response", an OpenAI Responses-compatible endpoint with function, custom and web-search tools and streaming events, as published in https://...

Agent Skills 5
An agent skill packages the how-to for driving these APIs from an assistant — the prompts, the sequence, the guardrails — so the knowledge to use the API travels with it.

AGENT SKILLPricing 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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate 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.

RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.

FINOPSEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Moonshot AI Chat Completions Streaming API
AsyncAPI 2.6 description of the Moonshot AI streaming chat completions surface. Moonshot's `/v1/chat/completions` endpoint is OpenAI-compatible and, when invoked with `stream: t...
ASYNCAPISemantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

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.
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.

This is an independent, third-party profile of Kimi (Moonshot AI), 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.
