Buying & Credits
A prompt is a text instruction that guides an AI image generator to produce a specific style or subject. On prompt-market.jp, you can buy handcrafted prompts tuned for Japanese-style generation with SDXL, FLUX, Pony, Illustrious, and more. After purchase, the full prompt text is unlocked instantly.
Credits are the on-site currency. 1 credit = ¥1 (about $0.007 USD). You spend credits on trial generations (20–50 cr) and on-site generations with prompts you own. Top up on the Credits page.
You can test any prompt before buying. The result has a visible watermark and the prompt text stays hidden. Credit cost varies by model — GPT-image-2: 80cr, Nano Banana Pro: 60cr, Nano Banana: 40cr, others: 20–50cr.
Yes. As soon as Stripe processes your payment, the full prompt text is unlocked. Find your purchases under Account → Purchased Prompts.
We carry prompts for GPT-image-2 (OpenAI), Nano Banana Pro / Nano Banana (Google DeepMind), Grok Imagine (xAI), FLUX, SDXL, Pony Diffusion, Illustrious, Animagine, NovelAI V4, and SD 1.5. GPT-image-2, Nano Banana, and Grok Imagine can be run on-site instantly. Each prompt card shows the target model.
Due to the digital nature of prompts, we generally do not offer refunds after purchase. If the prompt content is materially different from its description, please contact support and we will review your case.
Credits have no expiration date at this time. They are forfeited if you delete your account.
Selling & Creators
Three steps: create an account → connect Stripe Express (identity verification) → submit your first prompt. Stripe Express supports Japanese bank accounts and most international banks.
We take 25% of each sale. You keep 75%. Example: a ¥1,000 prompt sale nets you ¥750, transferred directly to your Stripe Connect account.
Each sale triggers an immediate transfer to your Stripe Connect account. Stripe then automatically pays out to your bank account every Friday. Need it sooner? Use "Request Early Payout" in your Creator Dashboard — available when your balance is ¥5,000 or more, with a 1% fee. Funds arrive within 1–3 business days of the request.
Every time a buyer uses your prompt for an on-site generation, you earn 5 credits automatically — on top of the initial sale. The more popular your prompt, the more royalties accumulate.
Typically 24–72 hours. Prompts flagged clean by our automated scanner can be approved within a few hours. Prompts involving real people, minors, or suspicious copyright content will be rejected.
Japanese traditional clothing (kimono, miko, hakama), school uniforms, anime/cel-shading styles, and scenic settings (shrine, nature) perform especially well. Prompts with detailed descriptions and 4+ high-quality sample images convert best. GPT-image-2, Nano Banana Pro, and Grok Imagine are trending hard on X right now — prompts for these models have strong demand.
Yes. Even after submitting a draft, you can open the prompt detail page and generate additional sample images using credits (up to 8 total). We recommend adding at least 4 images before requesting review — listings with more images convert significantly better.
Currently each listing targets one model. If you have a prompt that works well with multiple models, we recommend listing them separately for maximum discoverability.
