How this service works
Each disposal split into short- and long-term portions by how long the consumed lots were held
Output
Returns each disposal split into discrete short-term and long-term sub-records, showing the realized gain or loss amount allocated to each portion, the holding period duration for each consumed lot, and the classification (short-term: held ≤1 year, long-term: held >1 year).
Example use cases
Crypto tax report preparation
“I have a list of ETH and USDC disposals from last year with lot-level detail — can you split each one into short-term and long-term portions so I know what to report on Schedule D?”
Real-time gain/loss dashboard
“For each trade my portfolio manager executes, I want to immediately see whether the realized gain is short-term or long-term — can you classify the holding period for each disposal as trades come in?”
Tax-loss harvesting strategy check
“I'm thinking of selling some positions — given my acquisition dates and current disposal prices, can you split the potential gains by holding period so I know which lots would generate short-term vs long-term gains?”
Technical details
Endpoint
POSThttps://evm-canon-base.onrender.com/lots/holding-periodWhen to prefer
Choose this endpoint when you need holding-period-aware tax lot splitting as a dedicated computation step, especially after running FIFO, HIFO, or average-cost matching on the same platform. Prefer it over general-purpose accounting APIs when you need EVM-native lot structures and exact short/long-term gain attribution per disposal rather than aggregate summaries.
Side effects
- Missing or malformed acquisition/disposal dates preventing holding period calculation
- Lots with zero or negative quantities causing division errors
- Disposal amount exceeding available lot inventory resulting in an error
- Unrecognized token identifiers or mismatched lot references
- Malformed JSON body returning a 400 Bad Request
- Service unavailable on free-tier Render cold start returning 503
