How this service works
Prompt Styles — a curated FLUX prompt-engineering cheat sheet: 12 proven style recipes, an aspect-ratio guide, and a tier picker for the paid /generate endpoints. Static JSON, answers in milliseconds. Spend $0.001 here before spending $0.25-$0.75 on a generation.
Output
A static JSON object containing: a list of 12 named prompt style recipes (with style name, description, and example prompt fragments), an aspect ratio guide mapping common ratios to ideal use cases, and a tier guide explaining when to use each of the paid generation endpoints. Also includes a count field indicating the total number of styles returned.
Example use cases
Choosing style before paid generation
“I want to generate a product photo but don't want to waste money on bad prompts — can you fetch the FLUX style guide from CoinopAI so I can pick the best recipe and aspect ratio first?”
Picking the right generation tier
“I'm not sure whether to use FLUX Schnell or FLUX 1.1 Pro for my artwork — pull up the tier picker guide so I can figure out which plan makes sense for my quality needs.”
Building a prompt template library
“I'm building an image generation pipeline and need all 12 proven FLUX prompt style recipes from CoinopAI's cheat sheet so I can let users pick a style when submitting requests.”
Technical details
Endpoint
GEThttps://imagegen.coinopai.com/prompt-stylesWhen to prefer
Use this endpoint before calling any paid FLUX generation endpoint on imagegen.coinopai.com. At $0.001 per call it is orders of magnitude cheaper than a generation call ($0.25–$0.75), making it ideal for agents that need to programmatically select a style, aspect ratio, or tier before committing to a generation. Prefer this over hardcoding style names or guessing aspect ratios.
Side effects
- Network timeout if the static endpoint is temporarily unavailable
- Unexpected schema change if the style list is updated — agents should not hard-code style indices
- Non-200 response if the x402 payment header is missing or malformed
