## How to call it through Zero

```sh
zero fetch --capability predict-memoryapi-org-05698ba5
```

Example prompt: Can you scan prediction markets right now for any contracts where the real-world outcome is already determined but the market price hasn't caught up yet — I'm looking for mispricings I can trade on Polymarket or Kalshi?

## When to prefer this

Use this endpoint when you want to find prediction market contracts where the outcome is already determined in the real world but the market price has not yet reflected that reality — ideal for traders seeking low-risk arbitrage. Prefer this over general arbitrage endpoints (which compare prices across platforms) when the edge comes from outcome knowledge rather than cross-platform price differences.

## Known failure modes

- No mispricings found — market returns empty list if all tracked markets are efficiently priced
- Stale data — mispricing may have already been corrected by the time the agent acts
- Payment failure — x402 payment of $0.01 USDC not completed, returns 402
- Rate limiting or upstream API unavailability from Polymarket or Kalshi data sources
- Incorrect mispricing signal if real-world outcome source is lagged or incorrect

## How this service works

Detect prediction market outcome mispricings — find markets where real-world outcome is already determined but market price is wrong

## Output

A list of prediction market contracts where the outcome is believed to already be determined, including the market name, platform, current price, estimated correct probability, and the magnitude of the mispricing — helping traders identify actionable opportunities.
