## 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 xspy-smart-followers-list-d512c0b7
```

Example prompt: Who are the smart followers of @0xDamien on Twitter — show me the high-signal crypto accounts following that handle.

## When to prefer this

Use this endpoint when you need to identify which high-signal, on-chain-active crypto accounts follow a specific Twitter/X user — ideal for KOL vetting, influence mapping, or understanding the quality of an account's audience. Prefer this over raw follower count endpoints when signal quality (not volume) matters.

## Known failure modes

- Username not found or account does not exist — likely returns resolved:false or empty data array
- Private or suspended account — may return empty results or an error code
- Payment not received (x402 flow incomplete) — request blocked before data is returned
- Rate limiting or quota exceeded — HTTP 429 or equivalent
- Malformed username in path parameter — HTTP 400 or similar validation error

## How this service works

Real-time KOL intelligence, smart follower graphs, and on-chain token signals from tweets. Pay only for the calls you make in USDC on Base or Solana. Agent-ready, no API keys required.

## Output

A JSON object containing a list of smart followers for the queried Twitter username, including each follower's display name, Twitter handle, Twitter user ID, total follower count, and their own smart follower count, plus a total count of smart followers found and a resolution status flag.
