How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
Returns an array of prediction market objects from Polymarket, each containing the market question, a URL, outcome names with implied probabilities (0–1 scale where 0.55 = 55% chance), lifetime and 24-hour USD trading volumes, liquidity, resolution date, category, and active/closed status. Also includes the effective query echo, count, source, and any findings flags (e.g. no_results, limit_clamped).
Example use cases
Track election outcome odds
“Search prediction markets for anything related to the US election — show me the top 20 active markets sorted by volume with their current implied probabilities.”
Crypto price bet research
“Find active prediction markets about Bitcoin price targets — I want to see the current odds and 24-hour trading volume for each one.”
Monitor macro event forecasts
“What are the top prediction markets about Federal Reserve interest rate decisions right now? Show me up to 15 active ones with their outcome probabilities.”
Technical details
Endpoint
GEThttps://netintel-production-440c.up.railway.app/prediction/marketsWhen to prefer
Use this endpoint when you need real-time crowd-sourced probability estimates for future events, especially crypto, politics, or macroeconomic outcomes. It is ideal for agents that need to surface implied market odds rather than compute them. Prefer this over general web search when you want structured, quantified probability data with volume signals from Polymarket's order book.
Side effects
- Invalid status value — returns finding 'invalid_status' and falls back to default
- No markets found for keyword — returns empty markets array with 'no_results' finding
- Limit out of range — clamped to 1–50 with 'limit_clamped' finding
- Upstream Polymarket API failure — no charge applied per NetIntel policy
- Network timeout from upstream data source
