Kimi K3 API from Russia: Two Working Ways to Connect (2026)

Kimi K3 is Moonshot AI's new flagship model, launched in July 2026. From Russia there are two practical routes: directly through the official Moonshot platform (you will need a non-Russian payment method), or through the OpenAI-compatible EvoLink gateway, where the same key also unlocks US models such as Claude Fable 5 and GPT-5.6. Already hold a foreign card and only need Kimi K3: take route 1. Want a working key in minutes and side-by-side comparisons with US models: start with route 2.

What Kimi K3 is

Kimi K3 is a model with a 1,048,576-token context window and always-on reasoning: alongside the final answer, the API returns the model's reasoning in a separate reasoning_content field. It targets software engineering, agentic workloads, and large-document work.

Official Moonshot platform pricing, per the official pricing page as of July 16, 2026:

Item	Price
Input tokens (cache miss)	$3.00 per 1M tokens
Input tokens (cache hit)	$0.30 per 1M tokens
Output tokens	$15.00 per 1M tokens

Prompt caching cuts input cost by 10x, so with a long system prompt or repeated context the effective price is well below the sticker price. Budget your own scenario with the K3 cost calculator.

Why you cannot simply sign up from Russia

There are two separate obstacles.

First, payment. Russian-issued Visa, Mastercard, and Mir cards are declined by the international payment processing Moonshot uses. Russian-language Kimi API guides on vc.ru confirm that a direct payment with a Russian card does not go through.

Second, registration. According to the same guides (as of spring 2026), the Moonshot platform restricts registration by geography. We do not recommend tricking the regional check: it violates the terms of service and risks an account ban. If registration is unavailable in your region, go straight to route 2.

Both obstacles have legitimate solutions. The difference between the two routes below is how many steps you have to take.

Route 1: Directly through the Moonshot platform

Connecting directly gives you official pricing and no intermediaries. The steps:

Register at platform.kimi.ai. If the platform rejects registration in your region, this route is not for you; skip to route 2.
Create an API key in the platform console.
Top up your balance. This is the critical step for Russian users; options below.
Point any OpenAI-compatible SDK at base_url https://api.moonshot.ai/v1 with model kimi-k3.

How to pay from Russia

The working options described in the vc.ru Kimi API guides, from easiest to most self-sufficient:

A payment intermediary (Oplatym.ru and similar). You pay in rubles, the service completes the payment for you. Fastest, but budget for the intermediary's fee.
A foreign bank card. Kazakhstan, Armenia, and Turkey are the typical jurisdictions where Russians open accounts. A one-time trip or remote onboarding solves payments long-term with no per-payment fee.
A virtual card with a foreign BIN. A middle path: quicker than opening a foreign account, but virtual-card services charge top-up fees.
A friend abroad. Free of fees, but depends on having such a friend and is inconvenient for regular top-ups.

For step-by-step instructions on each option, including service addresses and the exact order of actions, see the detailed vc.ru guide; this article gives you the decision map rather than duplicating their walkthrough.

What to avoid: purchased ready-made accounts and "we pay for anything" Telegram bots. In both cases you hand your account and keys to a third party, and the account risks a ban.

Route 1 suits developers who have already solved foreign payments and want Moonshot with no extra layer.

Route 2: Through the EvoLink gateway

EvoLink is an API gateway that serves Kimi K3 over an OpenAI-compatible interface. Registration and key issuance do not require a Moonshot account, and the same key works with models from other providers, including US ones.

Sign up at EvoLink.
Create a key in the dashboard and store it in an environment variable.
Connect with the same OpenAI SDK, changing only the base_url and the key:

python · openai sdk

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["EVOLINK_API_KEY"],
    base_url="https://direct.evolink.ai/v1",
)

response = client.chat.completions.create(
    model="kimi-k3",
    messages=[
        {"role": "user", "content": "Explain prompt caching in three sentences."}
    ],
    max_completion_tokens=1024,
)

print(response.choices[0].message.reasoning_content)  # reasoning trace
print(response.choices[0].message.content)            # final answer

Per the EvoLink kimi-k3 documentation, three parameters are worth knowing.

reasoning_effort currently accepts only max: K3 always reasons at full depth and this cannot be turned off.
max_completion_tokens ranges from 1 to 1,048,576 and defaults to 131,072.
Besides the OpenAI-compatible interface there is an Anthropic-compatible one (Messages API format). If your code is written against the Claude SDK, migrating to K3 comes down to swapping the key and the endpoint.

Which route to choose

Criterion	Moonshot platform	EvoLink gateway
Registration from Russia	Regional restrictions reported by vc.ru guides	No Moonshot account needed
Payment from Russia	Via an intermediary or a foreign bank card	International payment processing; the same options apply
Available models	Moonshot models only	Kimi K3 plus other providers' models, including Claude Fable 5 and GPT-5.6
API interface	OpenAI-compatible	OpenAI-compatible and Anthropic-compatible
Best for	You already hold a foreign card and only need Kimi	You want a fast start or several models behind one key

In fairness: the Russian market also has local AI API aggregators that accept ruble payments, and vc.ru regularly reviews them. If paying in rubles is your deciding factor, look at those too. Compare on three points: whether the catalog lists kimi-k3 itself (not just K2), the markup over official per-token prices, and whether the compatibility interface you need is offered.

Bonus: US models with the same key

One practical advantage of the gateway deserves its own section: EvoLink's catalog lists US flagship models next to the Chinese ones. We verified this against EvoLink's official documentation: Claude Fable 5 (claude-fable-5) is listed among the Messages API models, and GPT-5.6 has its own documentation section.

Why this matters in practice: before moving a production project to K3, run the same prompts through kimi-k3 and, say, claude-fable-5 by changing only the model parameter in the code above. A comparison on your own tasks tells you more than anyone else's benchmarks, with no second account and no second payment setup.

FAQ

Can I pay for Kimi K3 with a Russian card directly?

No. Russian-issued cards are declined by international payment processing at Moonshot and at foreign gateways alike. The working options are a payment intermediary, a foreign bank card, or a virtual card with a foreign BIN.

Why does K3's reasoning_effort only accept max?

It is a current limitation of the model's API: K3 always runs full-depth reasoning. The reasoning trace is returned in the reasoning_content field and the final answer in content.

What context size does Kimi K3 support?

1,048,576 tokens. The response limit max_completion_tokens is configurable from 1 to 1,048,576 tokens and defaults to 131,072.

How do I quickly check that access works from my network?

Run the minimal request from the code sample above. If nothing comes back, check your balance and key first, and only then look for network causes. We collected the typical API errors and fixes in the Kimi K3 error guide.
