## When to prefer this

Use this endpoint when you specifically need to identify blue-checkmark/verified followers of a Twitter/X account — for influencer vetting, PR targeting, audience credibility analysis, or competitive intelligence. Prefer this over a generic followers endpoint when the verified status of followers is the key signal. Best suited for cases where follower quality matters more than raw follower count.

## Known failure modes

- Username not found or account suspended — returns empty result or 404-equivalent error
- Username has no verified followers — returns empty list
- Rate limit exceeded on underlying Twitter API — may return partial results or error
- Invalid or malformed username (too long, unsupported characters) — validation error
- Requested page count exceeds maximum of 20 — rejected with schema validation error
- Payment failure (insufficient USDC balance) — 402 Payment Required returned before data is fetched

## How this service works

Get the verified (blue checkmark) followers of a specific Twitter/X user.

## Output

A list of verified (blue checkmark) Twitter/X user accounts that follow the specified username. Each page contains a batch of follower records; multiple pages can be merged into one response. The response stops early if there are no more results before the requested page limit is reached.
