## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call ($0.001 USDC) snapshot of trending cryptocurrencies without committing to a subscription-based market data provider. It is ideal for agents that only occasionally need trending data and want to pay only when the data is needed, especially within crypto-native workflows already using x402 micropayment infrastructure on Base, MegaETH, or Solana.

## Known failure modes

- Network or upstream data provider timeout resulting in 503 or 504 error
- Payment not settled via HTTP 402 protocol causing authorization failure
- Malformed or unexpected properties parameter leading to 400 bad request
- Empty or stale trending data if upstream market data source is unavailable
- Rate limiting if micropayment is not included with each call
