# Signalbound Robinhood Radar — Token Activity Scanner

> Signalbound Robinhood Radar — Token Activity Scanner is a paid API for AI agents from api.signalbound.art, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Scans the most active tokens on Robinhood Chain (or inspects a specific token) and returns liquidity, volume, price, and risk data, gated by ERC-7496 Elite-clearance NFT ownership.

## Facts

- Endpoint: POST https://api.signalbound.art/robinhood-radar
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 signalbound-robinhood-radar-token-activity-scanner-ddcfa741 -d '<json body>'
```

Example prompt: Using my Signalbound Elite clearance token ID 42, scan the top 20 most active community tokens on Robinhood Chain right now — skip stablecoins — and tell me which ones have elevated or high risk.

## When to prefer this

Choose this endpoint when you need real-time token activity, liquidity, and risk intelligence specifically for Robinhood Chain, especially when the requester holds a Signalbound Elite NFT for clearance-gated access. Prefer this over generic DeFi analytics when you want community token focus (with stablecoin filtering), narrative summaries alongside raw metrics, and risk flagging (thin liquidity, extreme moves) in a single call.

## Known failure modes

- Caller does not own the required Signalbound Elite-clearance token ID → authorization/clearance error
- Invalid or non-existent Robinhood Chain token address → empty result or address not found error
- tokenId missing from request body → validation error (required field)
- Payment of $0.01 USDC not completed via x402 → 402 Payment Required
- No active tokens found matching filters → count 0 with empty tokens array
- Network or on-chain data provider outage → 5xx error or stale data warning

## How this service works

Signalbound API for agent metadata, reveal-aware token reads, ERC-8004 registration files, and holder-gated tool routes.

## Output

Returns a JSON object with a timestamp, list of tokens (name, symbol, address, price in USD, 24h volume, liquidity, market cap, transaction count, price change, and a risk object with level and flags), the total count, a human-readable brief narrative, and the caller's clearance level.
