## 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 bluesky-author-style-profile-api-644a4804 -d '<json body>'
```

Example prompt: Can you pull the writing style profile for the Bluesky account @pfrazee.com — I want to see their style summary, top keywords, and how many posts they've made?

## When to prefer this

Use this endpoint when you need a structured, vectorized style profile of a specific Bluesky author — especially for downstream tasks like persona similarity search, content personalization, or autonomous agent social modeling. Prefer this over generic social scraping when you need both a human-readable style summary AND a machine-usable embedding in a single call. Ideal for agents operating on the AT Protocol / Bluesky ecosystem.

## Known failure modes

- Author handle not found or invalid — may return empty or error response
- Author has no posts — postCount zero and null arrays for keywords and embedding
- Rate limiting or payment failure if x402 payment header is missing or malformed
- Bluesky API downtime causing upstream fetch failure
- Handles with private or restricted accounts may return incomplete data

## How this service works
