## When to prefer this

Use this endpoint when you need real-time, accurate cryptocurrency price and market data from CoinMarketCap — the industry-standard source for crypto rankings and quotes. Prefer this over generic alternatives when you need CoinMarketCap's specific ranking, volume, and supply data, or when you need to query multiple coins simultaneously with optional multi-currency conversion. Best for portfolio valuation, price alerts, market monitoring, and any use case requiring authoritative crypto market metrics.

## Known failure modes

- Invalid or unrecognized symbol/slug/ID returns an error or empty data for that entry
- Requesting more than the allowed number of symbols in a single call may return a validation error
- Unsupported convert currency symbol causes a 400-level error
- Network or upstream data unavailability results in a 5xx error
- Insufficient USDC payment or failed x402 payment flow blocks the request
