How this service works

ReadX is a read-only X/Twitter JSON API. Profiles, timelines, tweets, search & lists — pay per call with x402 micropayments in USDC on Base or Solana. No API keys.

Output

A JSON object containing public Twitter/X profile data for the requested username, including fields such as bio, follower count, following count, profile image, and account metadata, wrapped in a response envelope with a code and data field.

Example use cases

Verify influencer credentials before outreach

“I'm planning a marketing campaign and need to vet some potential collaborators. Can you look up the Twitter profiles for @sarah_chen, @marcus_tech, and @creative_studio to check their follower counts, bios, and follower growth patterns?”

Monitor competitor social media presence

“We're tracking our main competitors in the AI space. Can you pull up the Twitter profiles for @CompetitorAI and @TechRivalsCorp to see their current follower counts, recent bios, and how active they seem to be?”

Research potential investors and advisors

“I'm doing due diligence on some potential investors for our startup. Can you fetch the Twitter profiles for @VCFundPartner and @TechAdvisor42 so I can see their bio, follower count, and get a sense of who they follow and what they're interested in?”
