## When to prefer this

Use this endpoint when you need a single scalar metric — the count of smart (high-signal crypto) followers — for a Twitter/X account, without needing the full list or individual follower identities. Ideal for quickly ranking or scoring KOLs by crypto audience quality, comparing multiple accounts, or setting thresholds for alerts. Cheaper and faster than fetching the full smart follower graph.

## Known failure modes

- Username not found or invalid — may return resolved:false or a 404-style error
- Account has no smart followers indexed yet — returns totalCount of 0
- Rate limit or payment failure via x402 protocol — returns 402 Payment Required
- Network timeout or xspy crawler unavailability — may return a 5xx error
- Malformed username parameter — may return a 400 Bad Request

## 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 response with a totalCount integer representing the number of smart followers (high-signal crypto accounts) following the specified Twitter/X account, along with a resolved status flag, HTTP code, and success message.
