Getting started with the CruxAI Developers API

CruxAI Developers is our public API platform — use CruxAI models in your own applications via API tokens, separate from the chat app. The dashboard is at ai.cruxinteractive.com/developers and requires a Crux ID sign-in.

API basics

• Base URL: https://ai.cruxinteractive.com/api/v1
• Endpoints follow a standard Messages-style request/response format, so most existing tooling works by changing the base URL, the API key, and the model name.

Endpoints

• POST /api/v1/messages — chat & completions (JSON or SSE streaming)
• POST /api/v1/images — text-to-image generation
• GET /api/v1/models — list available models, capabilities, and pricing

API keys

• Create keys in the dashboard; they look like crux_sk_live_...
• The full key is shown only once, at creation. Only a hash is stored, so if you lose it, revoke it and create a new one.
• Authenticate with Authorization: Bearer crux_sk_live_... (preferred) or x-api-key: crux_sk_live_...
• Up to 25 active keys per account; revoking takes effect immediately.
• Optional workspaces let you label and organize keys.

Keep keys server-side. Never expose them in client-side code, mobile binaries, or public repositories.

Not the same as CruxAI+

CruxAI Developers (API) and CruxAI+ (consumer subscription) are separate products with separate billing. CruxAI+ doesn't add API credits, and API credits don't affect the chat app.
