## 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 agent402-linkedin-article-generator-6e87c0ec -d '<json body>'
```

Example prompt: Write a standard-length LinkedIn article titled around why AI agents need on-chain payment rails, targeting CTOs at fintech startups, written in a direct first-person tone with a strong thesis, include a cover image, one inline image, and a companion post with 4 hashtags.

## When to prefer this

Choose this endpoint when you need a complete, publication-ready LinkedIn article with AI-generated images, live web research, structured sources, and a companion post — all in a single call. Prefer it over generic text generation when the output must include cover art, sourced references, and a formatted social media caption ready to paste into LinkedIn. Ideal when the user wants a finished deliverable, not a draft to polish.

## Known failure modes

- Topic string exceeds 600 characters — truncate or shorten the topic
- Invalid length enum value — must be 'short', 'standard', or 'long'
- Hashtag count out of range 0–5 — clamp to valid range
- Image generation failure — cover or inline images may be missing from response
- Insufficient research results — sources_listed may be low for very niche topics
- Payment failure via x402 — $1.10 USDC not available in agent wallet

## How this service works

Hand over a topic and get a publish-ready LinkedIn article back: grounded web research with cited sources, three headline options, a hook-first body under subheads with facts linked to their sources, key takeaways, a companion post with hashtags, and generated images delivered at LinkedIn's own sizes (article cover 1920x1080, link-share 1200x627, feed square and portrait, in-article 16:9) as inline JPEG under 3 MB. Optional byline, angle, audience, tone and CTA.

## Output

Returns a JSON object containing: a fully formatted markdown article with headline, subtitle, body, key takeaways and sources; a companion LinkedIn post with hashtags and character count; base64-encoded cover and link-share JPEG images with alt text and prompts; metadata including word count, image count, synthesis model used, and number of sources; and structured source list with URLs, titles, and snippets.
