Mistral Le Chat API key setup

Get your key

1. Open the Mistral Le Chat API keys page: console.mistral.ai/api-keys
2. Create an account and generate an API key.
3. Paste it into the Dracon BYOK provider keys, stored encrypted (AES-256-GCM), used browser-direct, works in every Dracon tool.

Get the key and test it

1. Open the Mistral Le Chat API keys page: console.mistral.ai/api-keys Create a key and copy the secret straight away.
2. Point your client at this provider's base URL: https://api.mistral.ai/v1 It speaks the OpenAI-compatible shape, so an OpenAI SDK client works against it with no adapter: only the base URL and the key change.
3. Prove the endpoint answers before you trust it. Send one call with no Authorization header: a live endpoint answers 401 Unauthorized, because it is waiting for a bearer key. The wording of that error differs by provider (some say invalid_api_key, others incorrect_api_key or Token is invalid), so read the 401 as the signal, not the error text.
4. Paste the key into the Dracon BYOK provider keys ; stored encrypted, used browser-direct, no relay.
5. Compare other provider plans when this subscription does not match your usage or budget.

Test the key

Both examples read the key from the MISTRAL_API_KEY environment variable, so the key stays out of the command line.

export MISTRAL_API_KEY="<YOUR_API_KEY>"

curl https://api.mistral.ai/v1/chat/completions \
  -H "Authorization: Bearer $MISTRAL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"mistral-large-latest","messages":[{"role":"user","content":"hi"}]}'

import os
from openai import OpenAI

# export MISTRAL_API_KEY="<YOUR_API_KEY>" first
client = OpenAI(
    api_key=os.environ["MISTRAL_API_KEY"],
    base_url="https://api.mistral.ai/v1",
)
resp = client.chat.completions.create(
    model="mistral-large-latest",
    messages=[{"role": "user", "content": "hi"}],
)
print(resp.choices[0].message.content)
