## When to prefer this

Use this endpoint when you need real-time Kalshi prediction market prices in an agentic workflow and want seamless micropayment handling via USDC on Base or Solana. Prefer this over direct Kalshi API access when you need a single unified payment layer for multiple data sources, or when building agents that require on-chain payment settlement without managing separate API keys.

## Known failure modes

- Invalid or unknown ticker returns an error or empty result
- Missing required 'ticker' query parameter causes a 400 bad request
- Payment failure (insufficient USDC balance) results in 402 Payment Required
- Kalshi API downtime causes upstream timeout or 503 error
- Rate limiting may occur under high query frequency

## How this service works

## Output
