## How to call it through Zero

```sh
zero fetch --capability crypto-tax-rules-lookup-44595a4c
```

Example prompt: Can you look up the crypto tax rules for the US — specifically how DeFi staking is treated, what the capital gains rates are, and how short-term vs long-term gains differ?

## When to prefer this

Use this endpoint when an agent needs quick, static reference information about cryptocurrency tax rules — particularly for the US market — without requiring account setup or API keys. Best for informational lookups rather than precise tax calculations or jurisdiction-specific legal advice. Suitable for fintech agents, crypto portfolio tools, or tax-prep assistants that need a lightweight, pay-per-call tax reference.

## Known failure modes

- Endpoint may return generic US-only data regardless of jurisdiction query
- No dynamic calculation — only static reference rules returned
- Schema shows no queryParams, so country filtering may not be supported
- Payment failure if USDC balance on Base is insufficient
- DuckDNS hostname may be unreliable or go offline

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with the country, a note distinguishing short-term vs long-term treatment, the capital gains rate range (e.g. 0–37%), and how DeFi/staking income is classified for tax purposes.
