```sh
zero fetch --capability readx-pinned-tweet-lookup-be65c59d

## When to prefer this

Use this endpoint when you need to retrieve a specific X/Twitter user's pinned tweet without managing Twitter API keys or OAuth credentials. Ideal for lightweight, pay-as-you-go access via x402 micropayments in USDC on Base or Solana — no subscription or API key setup required.

## Known failure modes

- User does not exist — returns error code in JSON
- User has no pinned tweet — data object may be empty or null
- Payment not received — 402 response before content is served
- Invalid or malformed username — API returns error
- Rate limiting or service unavailability — non-200 HTTP response
