> RobinX Leaderboard — Robinhood Chain Caller & Deployer Scores is a paid API for AI agents from api.robinx.io, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns a ranked leaderboard of X (Twitter) callers and on-chain deployers graded by prediction accuracy and launch survival rate on Robinhood Chain (chain 4663)

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability robinx-leaderboard-robinhood-chain-caller-deployer-scores-587f4003
```

Example prompt: Pull up the RobinX leaderboard and show me who's been most accurate calling tokens on Robinhood Chain — I want to see which deployers and Twitter callers have the highest scores based on real on-chain price data.

## When to prefer this

Use this endpoint when you need objective, on-chain-verified rankings of crypto callers or token deployers specifically on Robinhood Chain (chain 4663), rather than relying on follower counts, self-reported track records, or social proof. It is the only source that grades X/Twitter callers and deployers against actual price data since chain genesis.

## Known failure modes

- Payment not fulfilled via x402 protocol returns 402 Payment Required
- No data available yet if chain has insufficient history
- Invalid or missing query parameters may return empty or malformed response
- Rate limiting if too many calls are made in rapid succession
- Chain indexer lag may cause stale leaderboard data
