Text-to-image, plus editing from a single input image (the input image is free). Billing: per image, quality × resolution — low 1K = 50, low 2K = 80, medium 1K = 80, medium 2K = 100 credits. Use POST /v1/cost for an exact quote. **Asynchronous.** Returns a job `id` (the image is not in this response). Poll [`GET /v1/images/{id}`](/api-reference/images/get-image-job-status) until `status` is `succeeded` — the generated image URLs are in that response's `images` array (each `{ url, position }`). ## OpenAPI ````yaml /openapi.yaml post /images/grok-imagine-image-2 openapi: 3.1.0 info: contact: email: support@budgetpixel.com name: BudgetPixel Support description: > The BudgetPixel developer API for programmatic image and video generation. Generation is **asynchronous**: you create a job, then poll its status until it reaches a terminal state (`succeeded` / `failed`). You are charged in credits only on success — never for failures, timeouts, or content blocked before generation. **Authentication.** All requests require an API key sent as a bearer token: Authorization: Bearer bpx_live_xxx Create and manage keys from your BudgetPixel account dashboard. The developer API is available on the **Premium** plan and above. **Pricing.** API usage is metered in credits at each model's published price (see `GET /v1/models`), and your plan's model discounts and active promotions apply to API charges exactly as they do on the web — `POST /v1/cost` quotes your discounted price. Pro and Ultra plans include a daily free-models allowance (a shared pool of free generations per day across qualified image models such as FLUX 2 Klein and the Qwen Image series) that covers API requests too — the standard price applies once the day's pool is used. Other promotional free daily generations remain web/app-only. Failed generations are never charged. **Rate limits.** Requests are limited per minute: **600 requests/min per API key** and **1200 requests/min per source IP** (defaults; subject to tuning). Every response carries `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` (seconds until the window resets). Exceeding a limit returns HTTP `429` with a `Retry-After` header — wait that long before retrying. Rejected requests still count against the window, so a tight retry loop keeps you limited; back off instead. Generation jobs additionally have a per-plan concurrency cap (the same one as the web workshop), independent of these request limits. `POST /v1/uploads` also has a dedicated **60 uploads/min per account** cap (it's free/unmetered) on top of these limits. title: BudgetPixel API version: '2026-06-20' servers: - description: Production url: https://api.budgetpixel.com/v1 security: - ApiKeyAuth: [] tags: - description: Account and credit balance name: Account - description: Discover available models and pricing name: Models - description: Upload input media for image/video generation name: Uploads - description: Image job status name: Images - description: FLUX image models name: Black Forest Labs - description: SeeDream image models name: Bytedance - description: Video job status name: Videos - description: Kuaishou Kling video models name: Kling - description: SeeDance video models name: ByteDance (SeeDance) - description: Music job status name: Audios - description: Music generation models name: Music - description: Format conversion for images, video, and audio name: Conversions - description: Publish posts to your BudgetPixel feed name: Social - description: Content moderation — NSFW rating and CSAM detection name: Moderation - description: Content classification — music genre detection name: Classification paths: /images/grok-imagine-image-2: post: tags: - xAI summary: Generate image with Grok Imagine 2.0 description: >- xAI Grok Imagine 2.0 — the latest Grok image model: precise editing, infographics, ads, game assets, UI/UX mockups and storyboards.
