## 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 signalpulse-compare-scanner-multi-instrument-trade-signal-comparison-b0598d7c
```

Example prompt: Compare the top golfers at this week's tournament — Scheffler, Morikawa, and Rahm — and give me a ranked confidence breakdown with a best 3-ball play recommendation and who to pick for fantasy.

## When to prefer this

Use this endpoint when you need to compare multiple specific players, assets, or instruments head-to-head and receive a ranked, confidence-scored signal with a clear best-play recommendation — especially for golf, sports matchups, FX pairs, or crypto comparisons rather than a broad market scan.

## Known failure modes

- Missing or unrecognized player/instrument names — returns empty or partial ranking
- Market type not supported — endpoint may return error or null results
- Insufficient market data for confidence scoring — low confidence scores returned
- Payment not fulfilled (x402) — 402 response requiring 0.5 USDC before result delivered
- Rate limit or Vercel cold start — slow or timeout response

## How this service works

Compare & rank 2+ named players against each other for AI betting, fantasy & research agents — golf 3-balls, DFS player pools, season-long start/sit, 'best of these'. Returns a ranked list (each with a projection + the case) plus the single best betting play AND the best fantasy/DFS value, off the deep engine: golf strokes-gained + course fit; tennis surface/form; combat style. Sizing, alerts & the tracked record are premium.

## Output

A JSON object with a tier label, a ranked array of players or instruments each with a confidence score and projection, a best_play object indicating the top pick and play type (e.g. 3-ball), and a fantasy_best pick.
