## 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 memestack-ai-meme-generator-50e0f1c4 -d '<json body>'
```

Example prompt: Generate a meme using MemeStack — the prompt is 'a cat wearing sunglasses at a board meeting saying nothing personal kid' — use standard quality mode.

## When to prefer this

Choose this endpoint when you need to generate a meme image from text and want it automatically captioned, tagged, and hosted on a shareable gallery URL without any account or API key setup. It is ideal for agents that need pay-per-use meme creation with instant hosting, especially when building social media automation or viral content workflows. Prefer quality mode for marketing or polished content; standard mode for rapid or high-volume generation.

## Known failure modes

- Payment insufficient or rejected — generation not triggered if x402/L402 payment fails
- Prompt violates content policy — generation refused with an error
- Grok Imagine service unavailable — upstream image generation failure
- Invalid mode parameter — falls back or returns an error if mode is not recognized
- Network timeout — long-running generation may not return in time

## How this service works

Generate an image from a text prompt with Grok Imagine; the result is hosted on MemeStack, AI-captioned and tagged, and returned as gallery and image URLs. 60 sats standard or 150 sats quality (USDC equivalent) per generation, chosen by the request's mode. No account or API key: the x402 (USDC on Base) or L402 (Lightning) payment is the auth.

## Output

Returns a gallery URL (the MemeStack page hosting the meme with caption and tags) and a direct image URL for the generated image, along with AI-generated caption and tags applied automatically.
