How this service works
Pay-per-use Twitter/X data API with x402 micropayments.
Output
A JSON object containing an array of verified follower objects (each with name, username, and is_blue_verified=true) plus pagination metadata including result_count and has_next_page, allowing the agent to iterate through all pages.
Example use cases
Identify credible brand advocates
“I need to find which verified accounts are following our brand on X so we can reach out to potential ambassadors—can you pull that list for us?”
Audit influencer audience quality
“Help me check how many blue-checkmark followers this tech influencer actually has—I want to know if their audience is genuinely credible before we consider a partnership.”
Monitor competitive follower base
“Can you get me the verified followers for our main competitor's Twitter account? I want to see what kind of credible audience they've built compared to ours.”
Technical details
Endpoint
GEThttps://twitter.surf.cascade.fyi/users/%7Bref%7D/verified_followersWhen to prefer
Use this endpoint when you need specifically the verified (blue-checkmark) subset of a Twitter/X user's followers, and want pay-per-call pricing via x402 micropayments rather than a subscription. Ideal for lightweight, one-off lookups or when you want to audit the credibility profile of an account's audience without paying for full follower data.
Side effects
- Invalid or non-existent user reference returns 404 or empty data array
- Insufficient USDC balance / failed x402 micropayment returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Private/suspended account returns 403 or empty result
- Malformed {ref} path parameter causes 400 Bad Request
