How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
A JSON object containing: trade side (long/short), risk in USD, reward in USD, position size in units, notional value, margin required, reward-to-risk ratio, estimated round-trip fees, risk after fees, estimated liquidation price, break-even win rate percentage, whether the stop is above the liquidation price, and a disclaimer note.
Example use cases
Leveraged crypto position sizing
“I want to open a leveraged ETH trade with a $5,000 account, risk 2%, entry at $3,200, stop at $3,050, and 5x leverage — what's my position size, margin needed, and liquidation price?”
Break-even win rate for a scalp trade
“For a $25,000 account risking 0.5% per trade with entry at $65,000, stop at $64,400, and target at $66,200 on Bitcoin, what win rate do I need to break even after fees?”
Risk check before placing a stop order
“Before I place this trade — $50,000 account, 1.5% risk, entry $180, stop $172, target $200, no leverage — can you confirm my dollar risk, reward-to-risk ratio, and estimated round-trip fees?”
Technical details
Endpoint
GEThttps://api.manylives.me/paid/trading/risk?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI trading agent needs to compute exact position sizing and risk metrics before placing a trade, especially for leveraged crypto or futures positions where liquidation price and margin requirements are critical. Prefer this over manual calculation when you need break-even win rate and fee-adjusted risk in a single call. It requires no account registration and charges only $0.005 USDC per call via x402.
Side effects
- Missing required parameters (account, risk_pct, entry, stop) return an error
- Stop price equal to or above entry for a long trade may produce nonsensical results
- Leverage outside 1-125 range may be rejected
- Non-numeric string values for price/account fields cause parsing errors
- Payment of 0.005 USDC not fulfilled results in HTTP 402 response
