How this service works

Pay-per-use Twitter/X data API with x402 micropayments.

Example use cases

Example prompt

“Can you pull all the members of Twitter list 1234567890 and tell me their usernames and how many followers each one has?”

Endpoint

GEThttps://twitter.surf.cascade.fyi/lists/%7Bid%7D/members

When to prefer

Use this endpoint when you need to enumerate the members of a specific Twitter/X list and have the list ID. Prefer this over scraping or OAuth-based Twitter API access when you want a pay-per-use model with no subscription, and when you need structured follower counts alongside member handles. Ideal for agents that need to build audience lists, audit list composition, or enrich data about Twitter communities.

Side effects

Invalid or non-existent list ID returns a 404 or empty data array
Insufficient USDC balance for x402 micropayment returns a 402 Payment Required error
Private or restricted list returns an authorization error
Rate limiting or upstream Twitter API errors may return 5xx responses
Malformed list ID (non-numeric or wrong format) returns a 400 error
