How this service works
Pre-trade risk check for AI agents trading crypto: live orderbook slippage at YOUR size, side-aware funding carry, open-interest crowding, and optional contract security — composed into a single ok/caution/avoid verdict with per-factor reasons and raw data embedded. Answers 'is this trade sane?' before trading, not after. Replaces four API integrations plus the judgment layer.
Output
Returns a structured verdict (ok, caution, or warning) plus four factor assessments: carry (annualized funding rate, risk level), crowding (long/short ratio, 24h OI change), liquidity (estimated slippage % for the intended size), and an optional GoPlus security scan if a token address was provided.
Example use cases
Example prompt
“Before I open a $50,000 long ETH position, run a pre-trade check — I want to see the funding carry, crowding levels, and slippage estimate.”
Technical details
Endpoint
POSThttps://agentpay.tools/tools/pre_trade_check/callWhen to prefer
Use this endpoint when an AI agent needs to autonomously evaluate trade risk before executing a crypto position — specifically when you want a combined funding carry + crowding + liquidity + optional token security assessment in a single call rather than querying multiple data sources manually. Especially valuable for agents managing real capital that need a quick go/no-go signal before entering perpetual or spot positions.
Side effects
- Unknown or unsupported symbol returns an error or empty factors
- Invalid ERC-20 address causes security scan to fail or be skipped
- Funding rate data temporarily unavailable causes carry factor to be skipped
- Very large position sizes may lack liquidity data for accurate slippage
- Payment not received (x402) results in 402 response and no data returned
