## 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 n0brains-real-time-crypto-trading-signals-ed4e04b7
```

Example prompt: Show me the top 20 long signals right now across all Coinbase-listed coins — I want whale flow and funding signals only, proven track record preferred, scored by confidence.

## When to prefer this

Use this endpoint when an agent needs real-time, pre-scored, multi-type crypto trading signals across a broad universe of coins — especially when the user wants to filter by direction (long/short), signal type (whale, funding, on-chain, etc.), or restrict to coins with a verified historical track record. Prefer over generic news or price feeds when actionable signal classification and conviction scoring are required.

## Known failure modes

- Invalid asset symbol returns empty signals array or 400 error
- Unsupported signal_type value may return no results
- Payment not confirmed results in 402 Payment Required response
- limit out of range (below 1 or above 200) returns validation error
- Network timeout if signal feed is momentarily unavailable

## How this service works

Real-time crypto trading signals for BTC, ETH, SOL and 400+ coins — classified by type (whale flows, funding, liquidations, listings, news, on-chain), scored, with direction, confidence and conviction. Emitted signals' forward-return record is public at n0brains.com/proof. Not financial advice.

## Output

A JSON array of trading signals, each including the asset symbol, signal type (whale flows, funding, liquidations, listings, news, on-chain), direction (long/short), confidence score, and conviction rating. Also returns a total count of signals matched and the amount paid per call.
