Bulk-generate images from a list of prompts with one API call (FLUX, no API key)

Description and use

The recipe enables bulk image generation from a list of prompts with a single API call, removing per‑image key handling and retries.

Problem

Generating hundreds of images from a list of prompts in a pipeline is cumbersome when each prompt requires a separate API call, key management, and bookkeeping.

Outcome

The recipe enables bulk image generation with a single API call, eliminating per-image key management, retry logic, and manual storage, while returning a structured dataset with URLs and status for each image.

Workflow

• 1. Create a free Apify account and copy the API token from Settings → Integrations.
• 2. Prepare a JSON input with fields such as prompts, imageSize, quality, imagesPerPrompt, seed, maxPrompts.
• 3. Call the Actor via curl, Python, or JavaScript to run the batch generation synchronously.
• 4. Retrieve the dataset items directly from the API response or via the Apify client.
• 5. Process each item: if status is "ok" use outputUrl; otherwise handle error.

Evidence

The pattern that removes all of this: one call that takes the whole list, runs the model, stores the files, and returns one record per image with its URL.
