Choose this endpoint when you need cryptocurrency ranking and price data and want to pay per-request in USDC on Base chain without managing a Coinranking API subscription. Ideal for agents that need occasional crypto market lookups without upfront API key setup.

## Known failure modes

- Payment failure if USDC balance on Base chain is insufficient
- Upstream Coinranking API unavailability causing proxy error
- Malformed or missing input parameters returning error response
- Rate limiting or quota exhaustion on the upstream Coinranking service
- Network timeout from the Vercel-hosted proxy layer
