How this service works
HostDeFi is a non-custodial Solana DEX. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, no accounts, no custody.
Output
A JSON object with a boolean ok flag, a count of returned markets, the source name (e.g. 'polymarket'), and an array of market objects each containing: slug, title, yesUsd price, noUsd price, vol24h (24-hour dollar volume), endDate, firstTs, lastTs, points score, and marketId (condition ID).
Example use cases
Monitor high-volume political markets
“Show me the 100 most-traded prediction markets right now with their current YES/NO prices and closing dates so I can track which political events are getting the most action.”
Scan for expiring markets to trade
“Get me up to 200 active prediction markets — I want to find ones ending soon so I can look for mispriced odds before settlement.”
Build a live odds dashboard
“Fetch the latest 50 prediction market listings including their slugs, YES/NO prices, and 24h volume so I can display a live odds board for my trading group.”
Technical details
Endpoint
GEThttps://hostdefi.com/api/v1/x402/predict/marketsWhen to prefer
Choose this endpoint when you need a live, paginated feed of prediction market listings with current YES/NO prices and volume data sourced from Polymarket, especially via an x402 micropayment-compatible API. Prefer this over scraping Polymarket directly when you need a clean JSON API with risk scoring context from HostDeFi's broader DeFi platform.
Side effects
- Invalid limit parameter (outside 1–500 range) returns a validation error
- Payment not included or insufficient USDC results in HTTP 402 Payment Required
- Upstream Polymarket data unavailable causes empty or error response
- Rate limiting if too many requests are made in quick succession
