## When to prefer this

Use this endpoint when an AI agent needs a quick, pay-per-call crypto price lookup without requiring a subscription to a traditional price feed API. Ideal for low-frequency queries where per-call micropayment via x402 is preferable to managing API keys or monthly plans. Best suited for agents operating in crypto-native or Web3 environments.

- Payment not processed results in 402 Payment Required response
