How this service works
Generate YouTube thumbnails with AI image models (GPT Image, Nano Banana, FLUX, Seedream, Ideogram, Grok) side by side. Optional query: models (comma-separated ids from https://thumbnailcreator.ai/llms.txt), n (1-4 per model), format (16:9, 1:1, 9:16, 4:5). Body: {"prompt": "3-2000 characters"}. Charged only when every image succeeds.
Output
Returns a JSON object with a generation ID, aspect ratio, status, total cost in micros, and an array of images — one per AI model — each with its own URL, model name, format, status, and individual price in micros (e.g. 167000 micros = $0.167).
Example use cases
YouTube video thumbnail creation
“Create a thumbnail for my YouTube video titled 'How to Build a PC in 2025' — make it look techy and exciting with a 16:9 format, and show me what different AI models like GPT Image 2 and FLUX come up with so I can choose the best one.”
Podcast episode cover art
“I need a square thumbnail for my podcast episode about mindfulness and stress relief — something calming with soft colors and a meditating figure. Give me several AI-generated options from different models so I can compare them.”
Online course promo thumbnail
“Generate a thumbnail for an online course called 'Master Python in 30 Days' — make it look professional and eye-catching, 16:9 format, with a coding aesthetic. I want to see what GPT Image 2, FLUX, and the other models each produce so I can pick my favorite.”

Endpoint
POSThttps://thumbnailcreator.ai/api/x402/generations?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare multiple AI image models for thumbnail generation in a single API call, want pay-per-image pricing with no subscription, need x402/agent-native payment support, or want to give a user a side-by-side choice of AI-generated thumbnails rather than committing to one model upfront.
Side effects
- Invalid or missing prompt returns an error response
- Unsupported format/aspect ratio value causes request rejection
- Payment failure via x402 protocol blocks generation
- One or more individual models may fail while others succeed, reflected per-image status
- Network timeout on long-running generations returns partial or empty image array
