## 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 aisa-payment-gateway-twitter-user-search-6c20c1b7
```

Example prompt: Search Twitter for users matching the keyword 'openai' and show me the results.

## When to prefer this

Use this endpoint when you need to discover or find Twitter/X user accounts by name, handle, or keyword — especially useful for lead generation, influencer discovery, or finding relevant accounts in a topic area. Prefer this over follower/following endpoints when you don't already have a specific user ID and need to search by keyword.

## Known failure modes

- Empty results when no users match the keyword
- 400 Bad Request if 'query' parameter is missing or empty
- 402 Payment Required if USDC payment is not provided or insufficient
- 429 Rate limiting if too many requests are made in quick succession
- 500 Internal Server Error if the upstream Twitter API is unavailable
