## 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 twitter-surf-cascade-fyi-ce9ba64b -d '<json body>'
```

Example prompt: Can you pull up the list of Twitter accounts that naval is following? Page through with a cursor if there are more results.

## When to prefer this

Use this endpoint when you need to retrieve the outbound social connections (following list) for a specific Twitter/X user by their username. Prefer this over general Twitter search when you specifically want to map who a user is following, build social graphs, or research someone's interests based on their follows.

## Known failure modes

- User not found - returns empty data array
- Private/protected account - following list may be inaccessible or empty
- Invalid cursor - pagination cursor expired or malformed
- Rate limiting - too many requests in a short period
- Empty result set - user follows nobody or API returned zero results

## How this service works

Returns the list of accounts followed by a given user reference.

## Output

Returns a paginated list of Twitter accounts the specified user follows, along with metadata including result_count, has_next_page boolean, and an optional cursor for fetching subsequent pages.

## Example request

```json
{
 "input": {
  "type": "http",
  "method": "GET",
  "pathParams": {
   "ref": "elonmusk"
  },
  "queryParams": {
   "cursor": ""
