## 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-token-pulse-live-x-chatter-caller-signal-for-robinhood-chain-8513cee1
```

Example prompt: Pull the RobinX pulse for token 0xABC123 on Robinhood Chain — I want to know the current X sentiment, what callers are saying, and whether any historically accurate callers are in the conversation.

## When to prefer this

Choose this endpoint when you need to assess the credibility-weighted social signal around a specific Robinhood Chain token — not just raw sentiment volume, but whether the people talking are historically accurate callers. Prefer this over generic sentiment APIs when operating specifically on Robinhood Chain (chain 4663) and when caller track-record grading matters.

## Known failure modes

- Token not found on Robinhood Chain — returns empty or error if the token address/ticker is invalid or not indexed
- No X chatter data available — token may be too new or have insufficient social activity
- Payment failure — x402 micropayment not processed, request rejected
- Rate limiting or API unavailability — service may return 429 or 503 under load
- Stale data — pulse may lag real-time X activity by some minutes

## 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 narrative string synthesizing live X chatter, a sentiment label (e.g. 'mixed', 'bullish', 'bearish'), and a count of measured (historically accurate) callers currently present in the conversation, plus a signal field identifying the result type as 'pulse'.
