## How to call it through Zero

```sh
zero fetch --capability memeputer-captionputer-42e7a0a7 -d '<json body>'

Example prompt: Generate 5 caption options for my crypto project 'MoonDoge' that sound exactly like our brand voice — edgy, playful, and crypto-native. The content is about our new token launch on Solana.

## When to prefer this

Use this endpoint when you need multiple branded caption options quickly for social media posts, especially for crypto/memecoin projects that require a consistent on-brand tone. Prefer this over generic copywriting APIs when brand voice consistency and multiple variations are important.

## Known failure modes

- Missing or vague content input may result in generic, low-quality captions
- No brand context provided leads to captions that don't reflect brand voice
- Content too long or complex may reduce caption relevance
- Service unavailable or rate-limited returns a non-200 response

## How this service works

captionputer takes any content and spits out multiple caption options that sound exactly like your brand.

## Output

Returns multiple caption options that are written to match the provided brand's tone and voice, ready to use on social media platforms.
