```

Example prompt: Can you pull me a snapshot of the top 100 cryptocurrencies right now — I need their current prices and market caps in JSON format?

## When to prefer this

Choose this endpoint when you need a quick, broad overview of the entire top-100 crypto market in a single call, especially when you want structured JSON output suitable for downstream analysis, portfolio valuation, or automated monitoring workflows. It is particularly useful for agents that need market-wide context rather than deep data on a single token.

## Known failure modes

- Payment not authorized or insufficient USDC balance — 402 Payment Required response
- Downstream market data provider outage causing stale or missing data
- Rate limiting if called too frequently in a short window
- Malformed response if the upstream data feed is temporarily unavailable
