## 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-player-comparison-ranking-engine-c21510c6
```

Example prompt: Compare Scottie Scheffler, Rory McIlroy, and Xander Schauffele for a 3-ball bet this Sunday at Augusta — rank them by strokes-gained and course fit, and tell me the single best betting play and best DFS value among them.

## When to prefer this

Use this endpoint when you need a head-to-head or small-pool comparison of named players rather than a whole-field scan. Ideal for golf 3-balls, DFS player pool decisions, start/sit fantasy choices, or 'best of these' betting questions where you already have a shortlist of players and want ranked projections with a concrete recommendation.

## Known failure modes

- Fewer than 2 player names provided — endpoint requires at least 2 named players to compare
- Unrecognized player names or misspellings cause lookup failures
- Unsupported sport type returns an error or empty projection
- Stale data window if called during an active live event with incomplete stats
- Payment failure (x402) if USDC balance is insufficient — call is not executed

## 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.

## Output

A ranked list of the submitted players, each with a projection value and the analytical case supporting their ranking, plus a highlighted single best betting play and the best fantasy/DFS value pick, powered by sport-specific deep signals (strokes-gained + course fit for golf, surface/form for tennis, combat style for MMA/boxing).
