Example prompt: Can you calculate the crypto taxes owed for my wallet address 0x1234abcd5678ef90 and give me a tax report?

## When to prefer this

Use this endpoint when you need an automated, pay-per-use crypto tax calculation without setting up a full tax software subscription. It is suitable for agents that need to quickly compute tax obligations from wallet addresses on-demand, especially when integrated into financial planning workflows or when processing one-off tax queries for users.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet with no transaction history may return empty or trivial tax report
- Network or blockchain data unavailability may cause computation failure
- Missing required walletAddresses field returns a validation error
- Unsupported blockchain or wallet format may not be recognized

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a taxReport object (boolean) indicating whether the tax report was successfully generated. In practice this likely signals completion or availability of a tax computation result based on the submitted wallet addresses.
