How this service works
Pre-execution safety verification for on-chain agent actions. Returns a proceed, wait, or block verdict with a confidence score and per-check breakdown, before your agent executes.
Output
Returns a verdict of 'proceed', 'wait', or 'block', along with a confidence score (0-1) and a per-check breakdown showing which individual safety checks passed, failed, or raised concerns for the proposed on-chain agent action.
Example use cases
Guard autonomous DeFi trade execution
“My DeFi agent is about to execute a swap on-chain — before it fires, run a safety verification on the action and tell me if it should proceed, wait, or be blocked, with a confidence score and what checks passed or failed.”
Policy gate for multi-agent blockchain workflow
“I'm running a multi-agent workflow where agents can trigger on-chain transactions — can you verify each proposed action through the safety guard before any of them execute, so only the ones with a clear 'proceed' verdict go through?”
Pre-execution check for NFT contract call
“My agent wants to call a smart contract to mint an NFT — run a pre-execution safety check on that action right now and give me the proceed/wait/block verdict with the full per-check breakdown before I let it go ahead.”
Technical details
Endpoint
POSThttps://api.verifyproceed.com/v1/x402/guard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs a real-time, pre-execution safety gate before committing any on-chain action — especially in autonomous or low-oversight workflows where you want a structured proceed/wait/block verdict with explainable per-check breakdowns rather than a simple pass/fail. It is particularly valuable when operating under custom safety policies, when transactions are irreversible, or when regulatory or risk considerations require an auditable pre-execution decision log.
Side effects
- Invalid or malformed action payload returns a 400 error
- Missing required action fields causes check failure or indeterminate verdict
- Payment not included or insufficient USDC results in 402 payment required
- Unrecognized on-chain action type may result in low-confidence or inconclusive verdict
- Network timeout or service unavailability returns 5xx error with no verdict issued
