## 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-twitter-banner-image-updater-42a521eb -d '<json body>'
```

Example prompt: Update the banner image on my X account to this image URL: https://example.com/my-new-banner.png — use my connected @MyBrandAccount credentials.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically update the banner/header image of an X (Twitter) account it controls, especially within autonomous workflows paid via USDC over x402. Prefer over direct X API integration when you want a simple paid API abstraction with async operation handling built in.

## Known failure modes

- Invalid or expired X account credentials — authentication failure
- Image URL unreachable or unsupported format — returns error on operation poll
- Image dimensions or file size exceed X platform limits — operation fails
- Rate limit exceeded by underlying X API — operation queued or rejected
- Polling operation ID not found or expired — returns not-found error

## How this service works

Update the banner image of an X account you control. Async: returns an operation to poll.

## Output

Returns an asynchronous operation object with an operation ID that the agent can poll to check completion status of the banner image update on the X account.
