## 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-verdict-on-chain-caller-deployer-grader-for-robinhood-chain-8cfd8760
```

Example prompt: Check the RobinX verdict for token 0xABC123 on Robinhood Chain — I want to know the deployer score, their launch track record, and whether the signal is buy or avoid before I ape in.

## When to prefer this

Use this endpoint when you need on-chain, data-driven accountability for token callers and deployers specifically on Robinhood Chain (chain 4663), rather than relying on follower counts or social hype. Prefer this over generic on-chain scanners when you want a graded verdict with signal and confidence, not raw transaction data.

## Known failure modes

- Token not found on Robinhood Chain (chain 4663) — returns error or empty data
- Invalid token address format — malformed request
- Token too new to have meaningful price history — low confidence score returned
- Payment not included or x402 payment rejected — 402 response requiring USDC payment
- Rate limiting or API unavailability — 5xx error

## 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

Returns a JSON object with a deployer_score (numeric reputation score), deployer_record (how many real vs launched tokens), a signal string (e.g. 'avoid' or 'buy'), and a confidence float (0-1) indicating how strong the verdict is based on on-chain price history since genesis.
