Example use cases
Stock trade sizing with risk cap
“I'm buying a stock at $150 with a stop loss at $140, I have $25000 in my account and never want to risk more than 2% on a single trade — how many shares should I buy?”
Crypto position sizing for day trader
“I'm entering Bitcoin at $60000 with a stop at $58000, my trading account has $5000 in equity and I want to risk 1.5% — what's the right position size?”
Options or futures risk check before entry
“My entry is $200, stop is $190, account equity is $50000, and my max risk per trade is 0.5% — can you calculate how many units I should trade?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/position-size-risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or trading workflow needs to programmatically compute position size based on fixed fractional risk management rules. It is ideal for agents managing trade execution pipelines, backtesting harnesses, or advisory bots that need per-trade risk sizing without building the math internally. It pays per result in USDC with no signup, making it suitable for lightweight or serverless agent workflows.
Side effects
- Missing required fields (entry, stop, equity, risk_pct) returns an error
- Stop price equal to or greater than entry price may produce undefined or negative results
- Extremely small risk_pct or very wide stop-to-entry spread may produce a position size of zero or fractional unit
- Non-numeric or malformed input values cause validation errors
- Payment failure via x402 protocol results in 402 Payment Required response
