Example prompt: Can you convert the hex string 0x1A3F to its decimal equivalent using the hex convert endpoint?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call hex conversion utility without setting up your own conversion logic, especially in blockchain or crypto contexts where USDC micropayment settlement via x402 on Base is already in use.

## Known failure modes

- Invalid or malformed hex string returns an error response
- Missing required input properties returns a 400 or empty example object
- Payment failure via x402 results in 402 Payment Required before any conversion is attempted
- Ambiguous input format (missing 0x prefix) may produce unexpected results

## 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

Returns the converted or decoded representation of the provided hexadecimal input, such as a decimal integer, ASCII string, or other formatted output depending on the conversion type requested.
