Example use cases

Influencer vetting for brand deals

“Can you look up the X profile for mkbhd and tell me their follower count, how many people they're following, and what their bio says? I need to vet them for a potential sponsorship.”

Competitor social media monitoring

“What are the current follower and post counts for the Twitter account openai? I want to track how their X presence compares to ours.”

Technical details

Endpoint

GEThttps://api.fastaf.co/x402/v1/x?utm_source=zero.xyz

When to prefer

Use this endpoint when you need structured profile metadata (follower count, bio, post count) for a specific public X/Twitter account by username. It is faster and cheaper than scraping X directly, requires no Twitter API credentials, and charges only on success. Prefer this over general web scraping endpoints when the specific output fields (name, bio, follower/following/post counts) are exactly what you need.

Side effects

Username not found or account doesn't exist — returns error response, no charge
Account is private or suspended — request may fail without charge
Missing or invalid profileId parameter — validation error
Username with @ prefix or full URL passed instead of bare handle — may fail to resolve
Rate limiting or upstream X API unavailability — request fails, no charge per policy
