## 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 readx-x-twitter-profile-about-endpoint-1b23ca97
```

Example prompt: Can you pull up the about/profile info for the X account @elonmusk using ReadX — I want their bio, description, and account details without needing Twitter API keys?

## When to prefer this

Choose this endpoint when you need public X/Twitter profile 'about' information for a specific user without managing Twitter API credentials, and you are comfortable paying $0.05 USDC per call via x402 micropayments on Base or Solana. Ideal for lightweight, occasional lookups where setting up Twitter developer API keys is impractical.

## Known failure modes

- Username not found — returns error code with empty data
- Insufficient USDC balance for x402 micropayment — payment fails and request is rejected
- Invalid or malformed username parameter — returns error response
- Rate limiting or upstream X/Twitter access issues — service temporarily unavailable
- Payment network (Base or Solana) congestion causing transaction delay

## How this service works

ReadX is a read-only X/Twitter JSON API. Profiles, timelines, tweets, search, lists, followers & following — pay per call with x402 micropayments in USDC on Base or Solana. No API keys.

## Output

A JSON object with code 0 and a data field containing the X/Twitter user's about/profile metadata such as bio, display name, follower counts, and account details for the requested username
