Endpoint
POSThttps://agenttoll.dev/paid/kalshi/marketsWhen to prefer
Use this endpoint when an AI agent needs structured, programmatic access to Kalshi prediction market listings — especially when filtering by category or controlling result count. Prefer this over scraping Kalshi's website directly, or when you need pay-per-call access without a long-term Kalshi API subscription. Ideal for agents doing market research, financial forecasting analysis, or monitoring prediction market availability across specific event domains.
Side effects
- Empty markets array returned if no markets match the specified category
- Payment failure if USDC balance on Base is insufficient for the $0.02 per-call fee
- Invalid category string returns empty or error response
- Limit value outside 5–100 range rejected with validation error
- Kalshi API downtime may result in upstream timeout or empty response
