How this service works
Pure quant math for AI trading agents: percent change, position sizing, rough liquidation price, DCA schedule, APR/APY. No market data feeds, no API keys. Pay-per-request USDC via x402 on Base and Solana.
Output
Returns a JSON object with the computed position size in units, the dollar amount at risk, and potentially the notional value of the position — derived purely from the mathematical relationship between account size, risk percentage, entry, and stop-loss price.
Example use cases
Crypto trade position sizing
“I want to buy Bitcoin at $65,000 with a stop loss at $63,000. My account is $25,000 and I never risk more than 1.5% on any single trade — how large should my position be?”
Forex lot sizing for risk management
“Size my EUR/USD position: account is $5,000, I'm risking 1% per trade, entry at 1.0850, stop loss at 1.0800. How many units or lots should I trade?”
Automated agent trade sizing pipeline
“Before I execute this ETH long, calculate the right position size — account is $50,000, risk per trade is 2%, entry $3,200, stop at $3,050. Give me the exact unit count to send to the exchange.”

Endpoint
POSThttps://agent-quant.annushka1190.workers.dev/v1/position-sizeWhen to prefer
Choose this endpoint when you need fast, pure-math position sizing with no external data dependencies or API key setup. Ideal for AI trading agents that already have market prices and need deterministic risk calculations on-demand, billed per-use in USDC. Prefer over spreadsheet tools or broker APIs when you need a lightweight, composable computation step in an automated pipeline.
Side effects
- Missing required fields (entry price, stop loss, account balance) returns a validation error
- Stop loss equal to or above entry price for a long (or below for a short) may cause a divide-by-zero or invalid result
- Malformed JSON body returns a 400-level error
- Payment failure via x402 (insufficient USDC balance) returns a 402 Payment Required
- Extreme input values (zero account balance, negative prices) may return an error or nonsensical result
