## 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 x-twitter-bulk-user-profile-lookup-c926ae34 -d '<json body>'
```

Example prompt: Can you look up the public profiles for these Twitter accounts — @elonmusk, @OpenAI, and @sama — and give me their follower counts, bios, and whether they're verified?

## When to prefer this

Choose this endpoint when you need to bulk-fetch public profile metadata (follower counts, bios, verification, account age) for one or more X/Twitter accounts by username or ID in a single call. It is ideal for influencer research, social graph enrichment, username-to-ID resolution, and any read-only social analytics workflow. Prefer it over scraping or direct X API integration when you need a simple, USDC-settled, agent-callable interface without managing OAuth or X developer credentials.

## Known failure modes

- Invalid or non-existent username/user ID returns an error or empty result for that entry
- Missing or invalid X_BEARER_TOKEN causes authentication failure
- Rate limits from the underlying X API v2 may throttle bulk requests
- Suspended or deactivated accounts may return partial or no data
- Exceeding batch size limits may cause request rejection
