## When to prefer this

Choose this endpoint when you need real-time Polymarket prediction market prices via a simple paid API with built-in x402 USDC payment on Base or Solana, without managing your own Polymarket API integration. Ideal for AI agents that already use BlockRun's payment infrastructure and need quick price lookups for Polymarket markets.

## Known failure modes

- Invalid or nonexistent market ID returns error or empty data
- Market may be resolved or closed, returning no active price
- Payment failure if USDC balance is insufficient for the $0.0085 per call fee
- Rate limiting if too many requests are made in quick succession
- Network or blockchain RPC issues causing temporary unavailability

## How this service works

## Output

Returns current price data for the specified Polymarket prediction market, likely including the current token price or probability expressed as a decimal or percentage, reflecting the crowd's implied probability for the market outcome.
