## 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 x402-trading-intelligence-api-924f8014 -d '<json body>'
```

Example prompt: Pull the aggregated trading signal for Ethereum right now — I want to see the weighted buy/sell score, whale activity, and the current Fear & Greed index reading.

## When to prefer this

Choose this endpoint when you need a holistic, multi-source crypto trading signal in a single call rather than hitting CoinGecko, Binance, and sentiment APIs separately. It is especially useful for agents that need whale detection and weighted opportunity scoring alongside raw price data, or when monitoring a broad universe of 13,000+ tokens for actionable signals. Prefer alternatives if you need raw tick-by-tick price feeds, order book depth, or execution capabilities.

## Known failure modes

- Token not found among 13,000+ supported assets — returns error or empty signal
- Upstream data source (CoinGecko, Binance, or Fear & Greed) temporarily unavailable, degrading signal quality
- Payment not processed via x402 protocol — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Invalid or malformed token symbol in request body — returns 400 Bad Request
