How to Use a Free AI API Without an API Key

In short: Two services answer AI requests with no account and no API key. Kilo AI Gateway has free models, up to 200 requests an hour from one IP address. OVHcloud AI Endpoints runs open models such as gpt-oss-120b, Llama 3.3 70B, Qwen and Mistral, up to 2 requests a minute per model. Both use OpenAI's chat format, so most apps and OpenAI's libraries work with them.

The two services that need no key

Every model named above answered a request with no key on 27 October 2026. OVHcloud serves its models from data centres in the EU. Its docs give the anonymous limit; with a paid OVHcloud key the limit is 400 requests a minute, billed per token.

Send a request with no key

Open a command window. On Windows, press the Start key, type PowerShell and open it. On a Mac, open Terminal.

Kilo AI Gateway, Windows (PowerShell):

$body = '{"model":"kilo-auto/free","messages":[{"role":"user","content":"Explain how AI works in a few words"}]}'
$r = Invoke-RestMethod -Method Post -Uri "https://ai-gateway.kilo.ai/api/v1/chat/completions" -ContentType "application/json" -Body $body
$r.choices[0].message.content

OVHcloud, Mac or Linux (Terminal):

curl https://oai.endpoints.kepler.ai.cloud.ovh.net/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-oss-120b",
    "messages": [{"role": "user", "content": "Explain how AI works in a few words"}]
  }'

The current model lists are at https://api.kilo.ai/api/gateway/models and https://oai.endpoints.kepler.ai.cloud.ovh.net/v1/models; both open without a key.

Use it in an app or in Python

Apps made for OpenAI usually ask for an API key even when the service does not need one. Enter any text as the key, the base URL from the table, and a model name. OpenAI's Python library works the same way:

from openai import OpenAI

client = OpenAI(base_url="https://oai.endpoints.kepler.ai.cloud.ovh.net/v1", api_key="no-key")
reply = client.chat.completions.create(
    model="Meta-Llama-3_3-70B-Instruct",
    messages=[{"role": "user", "content": "Explain how AI works in a few words"}],
)
print(reply.choices[0].message.content)

Free AI in apps, with no key

The OpenCode coding app includes its own free models, such as DeepSeek V4.1 Flash, with nothing to sign up for; they work only inside OpenCode. See how to install OpenCode.

When something goes wrong

Words to know

• API key: the password most AI services require. See what is an API key.
• Anonymous use: calling an API with no account and no key; the limit is counted per IP address.
• IP address: the internet address your requests come from; everyone on one network often shares it.
• Base URL: the address an app sends its requests to.

Free AI API keys

For higher limits, many services give free keys with a daily allowance: see how to get AI API keys for free, which lists each one with its limit and source.
