## When to prefer this

Choose this endpoint when you need a real-time ranked list of trending or hot sports cards with market comparables, especially for resale research, collection management, or market monitoring. It is pay-per-call via x402 on Base network (USDC), making it ideal for agents that need on-demand sports card market intelligence without a subscription. Prefer this over general sports data APIs when the specific focus is collectible card market movement and pricing comps.

## Known failure modes

- Payment failure on Base network — USDC payment not confirmed, request rejected
- Invalid `limit` parameter — value outside 1-40 range may cause error or fallback to default of 20
- Empty items array — no hot cards data available at query time
- Network timeout — endpoint at ephemeral hostname may be temporarily unreachable
- Rate limiting — rapid successive calls may be throttled

## How this service works

A pay per call service providing sports card market research data on the Base network.

## Output

A JSON object containing a `paid` boolean confirming successful payment, an `items` array of hot sports card records with market comparables data, and a `returned` integer indicating how many items were returned (up to 40).
