> Genexxis Odds Market Detail is a paid API for AI agents from odds.genexxis.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-30).

## 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 genexxis-odds-market-detail-24b27e5b
```

Example prompt: Pull up the full market detail for the Kalshi contract KXFEDDECISION-26OCT-H0 on Kalshi — I want the current bid/ask, implied probabilities, open interest, and how the price has moved over the last 24 hours.

## When to prefer this

Use this endpoint when you need deep detail on a single known prediction market — particularly when you already have the market id, slug, or ticker from a prior search. Prefer this over the search endpoint when you want bid/ask spreads, open interest, or granular 24h price history rather than just top-level odds across many markets.

## Known failure modes

- Invalid or unknown market id/slug/ticker returns an error or empty response
- Wrong venue specified (e.g. passing a Kalshi ticker as polymarket) causes lookup failure
- Market may be closed or resolved, returning no active bid/ask
- Rate limit or payment failure returns a 402 error
- Stale or missing price history if the market has low activity

## How this service works

One Polymarket or Kalshi market in detail: implied probabilities, last price, best bid/ask, spread, volume, open interest, 1-day price change and hourly price history for the last 24 h.

## Output

A JSON object containing the market question, venue, outcome names with implied probabilities, best bid and ask prices, last trade price, 1-day price change, open interest in contracts, and an array of hourly price points covering the last 24 hours.
