How this service works
RobinX grades every X (Twitter) caller and every deployer on Robinhood Chain (chain 4663) against real on-chain price since genesis — who called it early, who chased, whose launches survive. Receipts, not follower counts. Per call over x402, or one line of MCP.
Output
A JSON object containing the caller's X handle, an array of their individual token calls (each with token address, symbol, tweet timestamp, and outcome data including FDV in USD and whether the token is real), plus aggregated metrics: total call count, early call rate (0–1), and median 1-hour price move.
Example use cases
Vetting a crypto influencer before following
“Look up the RobinX track record for the X account 'cryptowizard' — how many Robinhood Chain calls have they made, what's their early call rate, and do their token picks actually survive?”
Comparing callers for a trading bot
“Pull the RobinX performance data for 'alphahunter99' on X — I need their call count, early rate, and median 1-hour price move on Robinhood Chain so I can decide whether to feed their calls into my strategy.”
Due diligence on a new follow recommendation
“Someone told me to follow 'moonshot_king' on X for Robinhood Chain plays — can you check their RobinX score and see if they actually call tokens early or just chase pumps?”
Technical details
Endpoint
GEThttps://api.robinx.io/caller/%7Bhandle%7D/callsWhen to prefer
Choose this endpoint when you need objective, on-chain-verified performance data for a specific X/Twitter crypto caller on Robinhood Chain (chain 4663), rather than relying on follower counts or self-reported track records. Ideal for agent workflows that vet signal sources, score influencer credibility, or filter caller feeds by proven accuracy.
Side effects
- Unknown or invalid X handle returns empty call array
- Handle with no Robinhood Chain calls returns zero metrics
- Rate limiting or payment failure over x402 returns 402 Payment Required
- Chain data unavailability may result in incomplete token outcomes
- Newly created X accounts may have insufficient history for meaningful scoring
