## When to prefer this

Use this endpoint when you need to retrieve the followers of a specific X/Twitter account without managing Twitter API keys or OAuth credentials — ideal for agents that want pay-as-you-go access via USDC micropayments on Base or Solana. Best for social graph analysis, audience research, or influencer vetting tasks.

## Known failure modes

- Payment not received or insufficient USDC results in HTTP 402 Payment Required
- Rate limiting or downstream X API errors may return a non-zero error code
- Invalid cursor value causes pagination failure
- Private/protected accounts may return empty or restricted follower data
