## When to prefer this

Use this endpoint when you need to investigate an account's identity history on Twitter/X, such as during due diligence, tracking rebrandings, verifying account continuity, or detecting impersonation. It is the only endpoint here focused specifically on historical handle/username changes rather than followers or token activity.

## Known failure modes

- Username not found — account does not exist or has been suspended
- Insufficient credits — fewer than 40 credits available on the account
- Rate limiting — too many requests in a short period
- No username history available — account has never changed its handle
- Invalid username format — @ symbol included or special characters used

## How this service works

Historical Twitter/X handle changes for an account, with change timestamps.

## Output

Returns a historical list of usernames that the specified Twitter/X account has used, including the handle at each point in time, allowing you to trace how the account's identity has changed over time.

## Example request

```json
{
 "input": {
  "type": "http",
