How this service works
Notional exposure from margin and leverage multiplier. Call when sizing futures/perps from account equity slices. Returns notional from margin×leverage as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
A deterministic JSON object containing the computed notional value derived from the product of the provided margin and leverage multiplier, with no external data sources or market feeds involved.
Example use cases
Pre-trade futures position sizing
“I'm planning to open a BTC perp position with 500 USDC margin at 20x leverage — calculate the total notional exposure so I can check if it fits within my risk limits.”
Equity slice allocation check
“I'm allocating 1500 USDC from my account equity as margin for an ETH futures trade at 5x leverage — what's the notional I'd be controlling?”
Leverage scenario comparison
“If I use 1000 USDC margin with 3x leverage versus 1000 USDC with 15x leverage, what are the two different notional exposures so I can compare the risk?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/leverage-notionalWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, local-math calculation of notional exposure from margin and leverage with no external dependencies, API keys, or live market data — ideal for pre-trade sizing checks, risk limit validation, and agent workflows on Base where a $0.001 USDC micropayment via x402 is acceptable.
Side effects
- Missing margin or leverage fields returns a validation error
- Non-integer values for margin or leverage may be rejected
- Zero leverage would produce zero or invalid notional result
- Payment failure via x402 prevents endpoint access
- Extremely large integers may cause overflow or unexpected results
