## 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 palmyr-x-account-username-changer-383952d8 -d '<json body>'
```

Example prompt: Change the @handle of my X account to @newcoolhandle using Palmyr.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically rename an X (Twitter) account that is registered and controlled via the calling wallet on Palmyr's infrastructure. It is ideal for automated social media management workflows where identity rebranding or handle rotation is required without manual intervention.

## Known failure modes

- Username already taken — 409 conflict returned
- Wallet does not own or have shared access to the specified X account — 403 forbidden
- Invalid username format (too long, special characters, etc.) — 400 bad request
- X API rate limit exceeded — 429 too many requests
- Payment not processed or insufficient USDC balance — 402 payment required
- X account not registered with Palmyr — 404 not found

## How this service works

Change the @handle of an X account you control.

## Output

Confirmation that the X account's username has been successfully updated to the new handle, or an error if the handle is unavailable or the wallet lacks access to the account.
