Common questions

You sign in through Clerk, the identity provider ModuleX uses. The first time you sign in, ModuleX creates your account and a personal starter organization for you automatically, so you always have somewhere to work right away. See the quickstart for the full first-run walkthrough.
Open your account’s API keys settings and create a key. It starts with mx_live_ and the full secret is shown only once, at creation time, so copy it immediately and store it somewhere safe. ModuleX keeps only a hashed copy and a short hint, so a lost key cannot be recovered — you delete it and make a new one. Step-by-step instructions are in the quickstart.
🎬 MEDIA PLACEHOLDER · MX-MEDIA-4500 · [SCREENSHOT] [SCREENSHOT_DESCRIPTION]: The API keys settings screen in the ModuleX app, showing the create-key flow and a newly generated key displayed once. [SCREENSHOT_DETAILS]: Capture the account API-keys settings page. Show the “Create API key” form (name field, optional organization scope, optional expiry, rate-limit field) and the success state where the full mx_live_* key appears once with a copy button. Redact the real secret. Light mode, 16:9, annotate the “copy now — shown once” callout and the masked hint (mx_live_2J9vK4xM********).
Two fast paths: run the quickstart to make your first authenticated request, or make your first API call to run a workflow and stream its result. If you would rather click than code, open the workflow builder in the app and run a sample workflow.
Use whichever fits the task — they all reach the same backend. Build visually in the web app, or do the same things from code with the REST API or the JavaScript and Python SDKs. Many people build in the app and then automate with the API.
Yes. The Free plan includes a one-time batch of 1,500 trial credits so you can try ModuleX before paying — no card required. Paid plans add a recurring monthly credit allowance: Pro includes 25,000 credits per month and Max includes 100,000 credits per month. Compare them on plans & pricing.
Pro and Max can also be billed annually. The annual amount shown in marketing may differ from the amount charged at checkout, so confirm the exact yearly price at checkout. See plans & pricing.
