How this service works

List members

Output

A paginated list of Twitter user accounts that are members of the specified list, including user profile data and a cursor for fetching additional pages.

Example use cases

Build outreach campaign from curated list

“Pull everyone from that tech industry Twitter list I bookmarked and give me their handles so I can see who to pitch our product to next month.”

Audit corporate social media strategy

“Show me all the accounts in our company's official influencer list and flag anyone who hasn't posted in the last 30 days—I need to know if we should update the membership.”

Monitor competitor tracking list members

“Fetch all the users from the competitors list we maintain and check if any new accounts have been added since last week that we should be watching.”

When to prefer

Use this endpoint when you need to enumerate or audit the members of a specific Twitter/X list, build audience lists from curated Twitter lists, or monitor membership changes in a list over time. Prefer this over manually browsing Twitter or scraping, especially when you need programmatic, paginated access to list members.

Side effects

Invalid or non-existent list ID returns an error
Payment failure (402) if USDC balance is insufficient
List is private and not accessible returns authorization error
Invalid cursor causes pagination to fail
Rate limiting may return 429 errors
