## 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 sawgrass-signals-upside20-equity-signal-7fc83b7c
```

Example prompt: Pull the latest Sawgrass Signals upside20 equity signal in JSON format — I want to see which stocks are flagged for top upside potential and the methodology behind the ranking.

## When to prefer this

Choose this endpoint when you need a pre-computed, quantitative upside signal for equities delivered as a single API call with micropayment billing — ideal for AI agents that want actionable stock screening output without building their own quant model. Prefer this over general financial data APIs when you specifically want a ranked upside screen with an explicit methodology, and when per-call USDC micropayment (x402) fits your cost model.

## Known failure modes

- Payment not completed or USDC balance insufficient — 402 response, no data returned
- Invalid format parameter — may return error or fall back to default format
- Signal data not yet refreshed for the current date — asOf timestamp may lag
- Endpoint temporarily unavailable — network or server error
- Rate limiting if called excessively in a short window
