## 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 fomoscan-user-theses-feed-0ed725b0
```

Example prompt: Show me the latest trade theses from the FOMO trader with user ID aefe2ddd-c580-5245-a2f5-e4ed62f7ef10 — grab the newest page from FomoScan.

## When to prefer this

Use this endpoint when you have a trader's stable user ID (from a prior resolve call or from an authorId field in another response) and want their full thesis history, newest first. Prefer the /token/{tokenAddress}/user sibling if you also have a specific token address to narrow results. If you only have a handle, resolve it to a user ID first with the handle-resolution endpoint.

## Known failure modes

- Invalid or non-existent user ID returns an empty list or 404 error
- Passing a handle instead of a stable user ID yields no results — must resolve handle to ID first using the handle-resolution sibling endpoint
- Stale or invalid before cursor causes a 400 or empty response
- Rate limiting or payment failure (x402) if the $0.01 USDC per call is not satisfied
- Network timeout on large thesis histories

## How this service works

Theses written by one FOMO trader, newest first. {id} is the stable user id (User.id / authorId), not a handle — resolve handle→id first if needed. Page with ?before= from nextBefore. Use the /token/{tokenAddress} sibling when you also know the token.

## Output

A paginated array of trade theses authored by the specified FOMO trader, ordered newest first. Each thesis includes the token referenced, the author's details, PnL/holdings data, and the thesis write-up text. The response also includes a nextBefore cursor for fetching older pages and a hasMore flag indicating whether additional pages exist.
