## 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 coinbase-usdc-pairs-ranked-crypto-signal-scores-34d809de
```

Example prompt: Pull the latest ranked signal scores for all 20 Coinbase USDC pairs and tell me which ones have the strongest buy or sell signals right now, including their prices and ATR%.

## When to prefer this

Choose this endpoint when you need a comprehensive, pre-ranked view of signal strength across all 20 Coinbase USDC pairs in a single call, rather than looking up a single pair or only the top-5 candidates. It is ideal for agents that need to scan the full market landscape, build watchlists, or identify outliers at both extremes of the signal spectrum.

## Known failure modes

- Payment not included or insufficient (x402 payment required, 0.001 USDC per call)
- Cloudflare tunnel unavailable or endpoint temporarily offline
- Stale data if update cycle has not completed within the expected 10-minute window
- Empty or partial results if fewer than 20 pairs are currently tracked
- Rate limiting or request throttling by the Cloudflare layer
