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.
Example use cases
Filing crypto taxes as a US investor
“I made some crypto gains this year — can you pull up the US crypto tax rules, especially the capital gains rates and how they differ for short-term versus long-term holds?”
Understanding DeFi staking tax implications
“I've been staking on some DeFi protocols and want to understand how staking rewards are taxed in the US — is it income, capital gains, or something else?”
Comparing crypto tax treatment across jurisdictions
“Can you check what the crypto tax rules look like for the US? I want to know the capital gains rates and whether DeFi is treated as taxable income there.”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/crypto-tax?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
