## When to prefer this

Use this endpoint when you need ranked price or market data for NOFX assets without needing API key registration, and are comfortable paying $0.002 USDC per call via an x402-compatible wallet. Prefer this over traditional REST APIs when operating in a permissionless, wallet-based payment context.

## Known failure modes

- Empty data array returned when no rankings are available for the given duration
- Payment failure or 402 response if USDC wallet is not properly configured
- Invalid duration parameter causes a malformed or empty response
- Service unavailability from vergex.trade backend results in error
- Unknown or unsupported duration value returns no results

## How this service works

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