How this service works
Realized gain/loss summary per disposal plus totals, without lot-level detail
Output
Returns a list of disposal events each annotated with realized gain or loss (proceeds minus cost basis), plus aggregate totals: total realized gain, total realized loss, and net realized gain/loss. No individual lot-level detail is included — only the per-disposal roll-up and summary totals.
Example use cases
Year-end crypto tax summary
“I need a realized gains and losses summary for all my token disposals this year — just the per-disposal totals and the overall net figure, no lot-level detail needed.”
Quick P&L check after token sales
“I just sold some tokens from my wallet — can you calculate the realized gain or loss on those disposals and tell me the totals so I know my tax position?”
DeFi portfolio gains reporting
“Can you summarize my realized gains and losses from all my on-chain swap and disposal events so I have a clean gains report I can hand off to my accountant?”
Technical details
Endpoint
POSThttps://evm-canon-base.onrender.com/lots/gainsWhen to prefer
Choose this endpoint when you need a clean, high-level realized gains summary per disposal plus overall totals and do not need to see which specific lots were consumed. It is simpler than the HIFO or average-cost endpoints when the default (typically FIFO) matching method is acceptable, and faster to interpret than lot-level detail endpoints. Prefer this for tax reporting, quick P&L checks, or passing summarized gain/loss figures to a downstream system without raw lot data.
Side effects
- Missing or malformed trade history input returns a 400 validation error
- Disposals with no matching acquisition lots may produce zero or error results
- Ambiguous token identifiers cause cost-basis lookup failures
- Insufficient funds for the $0.03 USDC x402 payment returns a 402 Payment Required
- Large trade histories may time out on the render.com free tier (cold start latency)
