Endpoint

GEThttps://www.surplusintelligence.ai/x402/api/twitter/v2/users/:userId/followers

When to prefer

Use this endpoint when you need to programmatically retrieve the follower list of a specific Twitter/X account by numeric user ID and want to pay per-call in USDC without managing your own Twitter API credentials. Prefer this over self-hosted Twitter API access when you need a lightweight, pay-as-you-go solution for follower graph analysis or social intelligence tasks.

Side effects

Invalid or non-numeric userId returns a 404 or Twitter API error
userId does not exist — returns Twitter API not found error
max_results out of range (less than 1 or more than 100) — schema validation error
Insufficient USDC balance for payment — 402 payment required failure
Rate limits from Twitter API upstream — may return 429 or error object
Private/protected account — followers list may be unavailable or empty
