## When to prefer this

Choose this endpoint when you need per-call, micropayment-gated top market data for a specific cryptocurrency token and are already operating in an x402/USDC payment environment on Base. Best for agents that need lightweight, on-demand crypto market lookups without a subscription.

## Known failure modes

- Invalid or unrecognized token ID returns an error or empty result
- Payment not settled via x402 returns HTTP 402 Payment Required
- Network/service unavailability on Render hosting returns 503
- Missing required 'id' query param may default to 'ethereum' or return an error
- Response schema is sparse (example: {}), so actual field structure may vary
