How this service works
Buy and sell amounts that bring a crypto portfolio to target weights, with optional new cash, drift band and fees, plus turnover and the biggest drift.
Output
Returns a JSON object with a per-asset breakdown (symbol, current USD value, target USD value, trade action, trade amount in USD, current weight, target weight, drift in percentage points), plus portfolio-level figures: total value, new cash added, total turnover, and the asset with the biggest drift. Includes a plain-language note explaining how to interpret the results.
Example use cases
Rebalancing after market drift
“My crypto portfolio has drifted — I have $8000 in BTC, $1500 in ETH, and $500 in SOL. Can you figure out the trades I need to make to get back to my targets of 50% BTC, 30% ETH, and 20% SOL?”
Deploying new cash into existing portfolio
“I want to add $5000 to my crypto portfolio which currently holds BTC:$10000, ETH:$4000, and SOL:$1000. Calculate how to deploy that cash so I end up at 60% BTC, 25% ETH, and 15% SOL.”
Checking portfolio drift before deciding to trade
“Can you tell me how far my crypto holdings have drifted from my targets? I hold BTC:$12000, ETH:$5000, MATIC:$3000 and my targets are 50% BTC, 35% ETH, 15% MATIC — show me the drift and what trades would fix it.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/crypto/rebalance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic calculation of crypto rebalancing trades — especially when you want per-asset buy/sell amounts, drift analysis, and turnover computed in one call without executing any actual trades. Prefer it over general financial APIs when you specifically need crypto portfolio weight normalization with optional cash injection.
Side effects
- Missing required 'holdings' parameter returns an error
- Missing required 'target_weights' parameter returns an error
- Target weights that don't sum to 100 may produce incorrect or error results
- Malformed symbol:value pairs (wrong delimiter or format) cause parse errors
- Negative new_cash_usd exceeding portfolio value may yield nonsensical results
