How this service works
Search open Polymarket and Kalshi markets by keywords; each market with outcomes and implied probabilities, 24h volume, liquidity or open interest, end date and link, ranked by match then volume.
Output
A JSON object with a count, the original query, and an array of matching markets. Each market includes: unique ID, venue (polymarket or kalshi), question text, outcome names with implied probabilities, 24h USD volume, liquidity or open interest (depending on venue), end date, URL, and a matchScore indicating relevance. Results are sorted by matchScore then 24h volume descending.

Technical details
Endpoint
GEThttps://odds.genexxis.com/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or survey prediction markets across both Polymarket and Kalshi simultaneously using keyword search. Prefer this over the detail endpoint when you don't know a specific market ID yet and need to find relevant markets by topic. Prefer this over the trending endpoint when you have a specific topic in mind rather than wanting the globally most-traded markets.
Side effects
- No matching markets found returns an empty markets array with count 0
- Missing required 'q' parameter returns a 400 error

- Payment not included or insufficient returns a 402 Payment Required response
- External API downtime from Polymarket or Kalshi may result in partial results or errors array entries
- Very broad queries may return unrelated markets due to keyword matching
