## 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 payweave-twitter-lookup-user-profile-by-username-c4c1968b
```

Example prompt: Can you look up the Twitter profile for the username 'paulg' and tell me their bio, follower count, and whether they're verified?

## When to prefer this

Choose this endpoint when you need to resolve a single Twitter/X screen name to a full public profile object in real time, especially when you want pay-per-call billing with no subscription commitment. Prefer it over scraping or official Twitter API v2 when you need instant per-query micropayment pricing via x402/USDC and don't want to manage API keys or rate-limit tiers.

## Known failure modes

- Username not found: returns an error or empty result if the handle does not exist or the account is suspended
- Rate or quota limits from the underlying twitterapi.io provider causing transient failures
- Malformed or missing username input (minLength:1 not met) causes schema validation rejection
- Network or payment settlement failure under x402 protocol resulting in no response
- Private or deactivated accounts may return limited or no data

## How this service works

X/Twitter data — tweets, users, communities, lists, articles, and trends.

## Output

A user-profile JSON object forwarded verbatim from twitterapi.io, typically containing fields such as display name, screen name, bio/description, follower count, following count, tweet count, account creation date, profile image URL, and verification status.
