Technical details
Endpoint
GEThttps://api.verigrace.com:4450/api/tax-report?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, accountant-ready FIFO tax cost-basis report specifically for a Base chain wallet. It is ideal when you need taxable event granularity, event-time price interpolation, and mark-to-market USD values in a single JSON payload. Prefer this over manual on-chain data aggregation or generic portfolio trackers when the output must be suitable for tax filing purposes.
Side effects
- Invalid or non-existent Base wallet address returns an error
- Payment failure via x402 (insufficient USDC or wrong network) blocks report generation
- Wallet with no transaction history may return empty ledger
- Rate limits or upstream Blockscout/CoinGecko data unavailability may cause partial or failed reports
- Non-Base chain addresses (e.g. Ethereum mainnet) are not supported
