Example prompt: What cryptocurrencies are trending the most right now? Give me the top coins ranked by search interest along with their prices, market caps, and 24-hour changes.

## When to prefer this

Choose this endpoint when you need a pre-ranked list of currently trending cryptocurrencies by search interest without specifying individual coin IDs. It is ideal for discovery use cases, trend monitoring dashboards, newsletter content, and surfacing momentum plays. For historical prices, detailed OHLC data, or data on a specific coin, prefer the Crypto Market Data or Crypto Price Lookup sibling endpoints instead.

## Known failure modes

- Upstream data provider outage may return 503 or empty coin list
- Micropayment failure (402) if USDC balance is insufficient or x402 facilitator is unavailable
- Rate limiting may occur with excessive rapid polling
- Trending data may lag by a few minutes during high-traffic periods
