How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object containing the queried asset name, a note about data interpretation, and an array of prediction market events. Each event includes the event description (e.g. 'Bitcoin above ___ on October 3?'), a close timestamp, an array of price levels with their associated probability-of-being-above percentages, and an approximate implied median price derived from the market.
Example use cases
Bitcoin price target probability check
“What probability does Polymarket assign to Bitcoin being above $90,000 and $100,000 in the next major event? Give me the implied median too.”
Ethereum market sentiment gauge
“Pull the Polymarket prediction market odds for Ethereum price levels — I want to see which price targets are seen as likely and what the implied median is.”
Solana options strategy research
“I'm considering a Solana options play — can you get me the Polymarket implied probabilities for Solana being above various price levels across upcoming events so I can compare them to options pricing?”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/polymarket-crypto-odds?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need crowd-sourced, market-implied probability distributions for specific crypto asset price levels — particularly when you want Polymarket's event-based odds rather than traditional options-derived implied volatility. Ideal for gauging prediction market sentiment, comparing market-implied probabilities to model estimates, or research into crowd wisdom on crypto price targets. Not suitable for real-time price feeds or historical price data.
Side effects
- Unsupported asset name returns empty or error response
- Polymarket may have no active events for a given asset at query time, returning an empty events array
- Stale or illiquid markets may produce wide spreads and unreliable implied medians
- Network timeout if Polymarket data source is temporarily unavailable
