Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/coinmarketcapWhen to prefer
Choose this endpoint when you need real-time or near-real-time CoinMarketCap data within an x402-enabled, crypto-native agent workflow paying with USDC on Base. It's ideal for agents that already operate on-chain and want a single metered API gateway to CoinMarketCap without managing a separate API key.
Side effects
- Payment failure via x402 if wallet has insufficient USDC on Base mainnet
- Invalid or unsupported operation name returns an error
- Malformed input parameters cause provider-level errors
- CoinMarketCap API rate limits or downtime propagate as upstream errors
- Unsupported cryptocurrency symbol returns empty or error data
