## 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 aizamon-bot-fuel-polymarket-kalshi-arbitrage-signal-49be3ae3
```

Example prompt: Pull the top Polymarket vs Kalshi gap and net-edge signal right now so my trading bot can act on the best arbitrage opportunity available today.

## When to prefer this

Choose this endpoint when your agent or bot needs a ready-made, pre-ranked arbitrage signal across Polymarket and Kalshi without building your own cross-exchange gap scanner. Ideal for spend-capable wallets already set up for x402 micropayments that want a low-friction $0.25-per-call signal feed rather than integrating directly with both exchange APIs.

## Known failure modes

- Payment not processed or wallet not spend-capable — returns 402 Payment Required
- No significant gap found between markets — returns empty or low-confidence result
- Market data temporarily unavailable — returns 503 or stale signal
- Rate limit exceeded for pack/day quota — returns 429 Too Many Requests
