The CentML platform lets you create API tokens for both Serverless endpoints and other CentML solutions. The CentML platform also allows you to generate other Vault It is worth noting that Serverless API Keys do not work on general CentML solutions and Bearer Tokens do not work on serverless endpoints. You will need to create one of each if you’d like to use CentML LLM endpoints as well as CentML serverless endpoints. This guide will walk you through creating both Bearer Tokens, Serverless API Keys, and other Vault objects you can use to configure or access CentML services.

​

Step 1: Login to the CentML Platform

Regardless of if you are creating Serverless API Keys, Bearer Tokens,or other Vault objects you will need to login to the CentML platform. If you do not know how to login or do not have an account, please follow the Creating an Account documentation before proceeding.

Once logged in, you will need to select Account from sidebar menu, and then click on the Vault tab from the Your Account window.

Once completed, move onto the second step below based on the type of Vault objects you are creating.

​

Step 2A: Creating Serverless API Keys

Serverless API Keys are used for accessing the CentML serverless endpoints either via the UI or API calls directly. To create a key, click on the green Generate button on the Your Account screen.

Your newly generated key should appear above your vault.

You can now use your Serverless API Key, to make progrmmatic requests or access the serverless chat UI.

​

Step 2B: Creating Bearer Tokens

Bearer tokens can be used to access CentML services except for serverless endpoints.

To generate a bearer token, select green Add Vault Item. A dropdown menu will appear. From that menu, select the Bearer Tokens option.

A windows will pop up name Add Bearer Token to Your Vault. From there, you can either name and automatically generate a token with the Generate new Bearer Token option or you can enter a previous token using the Use an existing Bearer Token option.

Once you either enter your token in the text box or opt into generating your token, click the green Add to Vault option and your Bearer Token should appear in your vault.

​

Step 2C: Adding Certificates to Your Vault

CentML uses client certificates for mutual TLS (mTLS) You can generate or add public certificates for mTLS just like you can with Bearer Tokens. Once you generate the certificate, it will appear in the vault.

When generated,Vault Certificates generate a .pem file that is downloaded to your local browser. That .pem file is named after the generated cert. You can then use that .pem file to access one of CentML’s private endpoints as long as they are associated with the appropriate certificate and .pem pair.

Example usage

curl -X POST 'https://centml-private-2.fe178792.c-09.centml.com/openai/v1/chat/completions' \
  --cert gen-cert.pem \
  -H 'Accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
    "messages": [
      {
        "role": "user",
        "content": "what is the meaning of life?"
      }
    ],
    "model": "meta-llama/Llama-3.2-3B-Instruct",
    "max_tokens": 512,
    "n": 1,
    "presence_penalty": 0,
    "stream": true,
    "stream_options": {
      "include_usage": true
    },
    "temperature": 0.7,
    "top_p": 1
  }'
