Example use cases

Technical details
Endpoint
GEThttps://pro-api.coingecko.com/api/v3/x402/onchain/simple/networks/polygon_pos/token_price/probeWhen to prefer
Use this endpoint when you need real-time onchain DEX-sourced price data for a specific token on the Polygon PoS network identified by its contract address. Prefer this over CoinGecko's off-chain endpoints when you need DEX liquidity-based pricing rather than CEX-aggregated prices. Best for DeFi tokens that may not be listed on centralized exchanges but trade on Polygon DEXes like QuickSwap or Uniswap v3.
Side effects
- Invalid or unrecognized contract address returns empty or null data
- Token not indexed on Polygon PoS DEX returns no price data
- Missing required contract address parameter causes 400 error
- Rate limit exceeded causes 429 error
- Inactive token with no recent trades may return stale or missing data
- Network identifier mismatch causes no results
