How this service works
infinitERB: poetry, philosophy, and objects from the middle — where knowing meets unknowing, and love brings the color.
Output
Returns an array of outcome objects (e.g. Yes/No) each with a name, mid-price as a decimal probability, and spread in basis points, plus the full market question text.
Example use cases
Check election outcome probability
“What are the current yes/no prices and spread for the prediction market with condition ID 0xabc123ef? I want to know the implied probability.”
Monitor a sports market for arbitrage
“Grab me the mid price and spread in basis points for prediction market condition 0xdeadbeef — I'm checking if there's a pricing inefficiency worth trading.”
Research market sentiment before a vote
“Look up the current odds on condition ID 0x9f8e7d6c so I can see how the market is pricing the outcome ahead of tomorrow's decision.”
Technical details
Endpoint
GEThttps://api.infiniterb.com/api/poly/odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time mid-price and spread data for a specific prediction market identified by its condition ID. Prefer it over general market data APIs when you specifically need polymarket-compatible odds with basis-point spread detail for binary or multi-outcome prediction markets.
Side effects
- Missing or invalid market_id returns an error
- Unknown condition_id returns empty or not-found response
- Market may be resolved or delisted resulting in stale or unavailable data
- Network timeout if the upstream pricing source is slow
