## When to prefer this

Choose this endpoint when you need to rank cryptocurrency markets or trading pairs specifically by trade count (number of transactions), especially when you want to filter by product type (spot, futures, etc.) and need wallet-based micro-payment access without API key registration.

## Known failure modes

- Empty data array returned if no results match filters
- Non-zero code on invalid parameter values
- Payment failure (402) if USDC wallet balance is insufficient
- Request rejected if invalid sortType or productType enum value is provided
- Timeout if upstream CoinAnk data is unavailable

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.
