## 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 wafermap-xyz-x-post-writer-60e9e32f -d '<json body>'
```

Example prompt: Write me three X post drafts about the launch of my new DeFi analytics dashboard — use a confident tone and keep each one under 280 characters.

## When to prefer this

Choose this endpoint when you need multiple ready-to-post X drafts quickly with a specific voice — confident, playful, technical, or minimal — without manually iterating on a general LLM. Ideal for agents automating social media workflows or helping users batch-create tweet content on a topic in a consistent tone.

## Known failure modes

- Topic too vague — drafts may be generic or off-target
- Invalid tone enum value causes a validation error
- Topic exceeds 1500 character limit — request rejected
- Model occasionally produces drafts slightly over 280 characters requiring manual trimming
- Payment failure via x402 protocol results in 402 response before content is generated
