How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
Returns a JSON object containing an array of prediction market listings sourced from Polymarket, Kalshi, or both. Each market entry includes the source platform and market-level data such as the event, current odds/probabilities, and metadata. The number of results is bounded by the requested limit (5–100).
Example use cases
Political event probability tracker
“What are the current prediction market odds on Polymarket for the top 20 political events? I want to see what probabilities the market is pricing in right now.”
Cross-platform odds comparison
“Grab the latest markets from both Polymarket and Kalshi — up to 100 results — so I can compare odds across the two platforms and spot any discrepancies.”
AI agent market sentiment monitor
“Fetch the top 30 prediction markets from Kalshi right now so I can monitor overall market sentiment and see which upcoming events traders are most focused on.”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/odds/feedWhen to prefer
Use this endpoint when you need a broad feed of current prediction market odds from Polymarket, Kalshi, or both simultaneously. It's ideal for market surveillance, sentiment analysis, and cross-platform comparison. Prefer this over single-platform SDKs when you want a unified, pay-per-call interface without managing API keys for each exchange, or when operating within an x402/MCP agent environment that handles micropayments natively.
Side effects
- Invalid platform enum value returns a validation error
- Limit outside 5-100 range causes schema rejection
- Upstream Polymarket or Kalshi API downtime results in empty or partial markets array
- Payment failure (insufficient USDC balance or x402 rejection) blocks access
- Malformed bodyType field causes request rejection
