Profile & API Keys

The Profile page (/profile) shows your coin balance, spending history, model access, and your personal API keys.

At the top of the page, a card shows your identity and a summary of your account activity.

The left side displays your avatar (pulled from Gravatar based on your email), your display name, and email address.

The right side shows six stat tiles:

Tile	Description
Groups	The groups you belong to
Coins Used	Total coins spent across all models, all time
Tokens Used	All input + output tokens across all models, all time
Favorite Model	The model you have used most
Coins Available	Your current pool balance with a progress bar (when a limit is set)
Refill Rate	Auto-refill rate per hour and a countdown to the next refill

Coin Pool Values

Value	Meaning
A positive number	Coins remaining in your budget
Unlimited	No cap — you can always send requests
—	No budget has been set up for your account
0 or negative	Budget exhausted; further requests are blocked until a refill or an admin grants more coins

Web Chat Usage

Below the stat cards, a row summarizes your web chat activity:

Column	Description
Conversations	Number of conversations you have started
Requests	Total messages sent through the chat interface
Tokens	Total input + output tokens via web chat
Coins	Total coins spent on web chat
Last Used	When you most recently sent a message

API Keys

API keys let you access Lumen's AI models from your own code, scripts, or compatible tools — without opening a browser.

What an API Key Is

An API key is a secret token in the format sk_.... It identifies you to the API the same way your login session identifies you in the browser. Each key has its own usage counters, so you can track exactly how much each integration is using.

Important: The key is shown only once when you create it. Copy it immediately — it cannot be retrieved later.

Creating a Key

Click + New API Key at the top of the API Keys section.
A dialog opens and displays your new key in a read-only field.
Copy the key now.
Enter a descriptive name (e.g., my-research-script or jupyter-notebook).
Click Save Key. The key now appears in the table.

Viewing Your Keys

The API Keys table shows all your active keys and lets you sort by name, requests, tokens, cost, or last used. Enable Show deleted keys to see previously revoked keys (displayed with strikethrough).

Column	Description
Name	The label you chose
Hint	First 4 + last 4 characters of the key, for identification
Requests	Total API calls made with this key
Tokens	Total input + output tokens
Coins	Total coins spent
Last Used	Timestamp of the last API call
Actions	Revoke button for active keys

Revoking a Key

Click Delete on any active key. The key is deactivated immediately — any code using it will start receiving authentication errors. Usage history is preserved and visible with "Show deleted keys".

Model Access

The Model Access table lists every model available in Lumen and your access status for each.

Column	Description
Model	Clickable link to the model detail page
Requests / Tokens / Coins / Last Used	Your personal usage stats for that model
Access	Your current access level (see below)
Status	Health of the model's backend

Access Levels

Badge	Meaning
Need Consent (warning)	Model requires a one-time acknowledgment — click to enable it
Consented (green)	You have acknowledged this model and can use it
Allowed (green)	Model is fully available to you
Blocked (red)	Model is not available to you

Model Status

Badge	Meaning
ok (green)	All backends healthy
degraded (yellow)	Some backends are down but at least one is working
down (red)	No healthy backends
disabled (gray)	Model is currently turned off

Click any column header to sort the table. Use the search box to filter by model name. Check Show disabled to include currently disabled models.
