## When to prefer this

Choose this endpoint when you need a pay-per-call, crypto-native hex conversion utility that settles in USDC on Base via x402 protocol, especially in agentic pipelines already integrated with x402 payment flows and needing lightweight numeric/hex transformation without standing up your own service.

## Known failure modes

- Invalid or malformed hex string returns an error
- Missing required properties parameter returns 400 or empty response
- Payment not settled in USDC on Base causes 402 payment required error
- Endpoint on Render free tier may experience cold-start latency or downtime
- Empty or null input may return an empty example object with no useful data

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output
