# CoinopAI ImageGen Prompt Styles Guide

> CoinopAI ImageGen Prompt Styles Guide is a paid API for AI agents from imagegen.coinopai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns a curated JSON cheat sheet of 12 proven FLUX prompt-engineering style recipes, an aspect-ratio guide, and a tier picker to optimize image generation requests before calling paid generation endpoints.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability coinopai-imagegen-prompt-styles-guide-f6c56cf2
```

Example prompt: Before I generate any images, pull up the CoinopAI prompt style cheat sheet so I can see which of the 12 FLUX style recipes and aspect ratios fit my project best.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
