🆓 Mnexium Free Tier — Easy API, No Signup

Quick update — we just launched a free tier that requires zero signup.

You can now use Mnexium without creating an account.

Just make an API call with your own OpenAI or Anthropic key, and we auto-provision a trial key for you on the spot.

await client.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "My name is Sam." }],
  mnx: {
    subject_id: "user_ID_123",
  }
});

No x-mnexium-key needed. We create one for you and return it in the response:

X-Mnx-Key-Provisioned: mnx_trial.abc123...

Save that key, use it going forward. Next time you ask "What do you know about me?" — it remembers.

What you get for free:

• 10,000 API calls/month

• 1,000 memory actions/month

• No expiry

Full feature access — memory, recall, profiles, claims, history, all of it

When you're ready to claim your key:

1. Go to mnexium.com/claim

2. Paste your trial key

3. Create an account (or use existing)

4. All your data transfers over — nothing lost

Lost your key? Pass "regenerate_key": true in the request and we'll issue a new one. Data stays intact.

We wanted to remove every barrier to trying Mnexium. No forms, no waitlists, no credit card. Just curl and go.
