How this service works
Verify an autonomous decision before execution
Output
Returns a verification result indicating whether the proposed autonomous decision is approved or rejected for execution, potentially including a confidence score, risk level, or reasoning about why the action is or is not safe to proceed.
Example use cases
Safe autonomous file deletion gate
“Before my agent deletes those old log files, run the decision through the verifier to confirm it's a safe and approved action.”
Financial transaction pre-approval
“My agent is about to transfer funds — can you verify that decision first and make sure it passes the safety check before executing?”
Agentic API call guardrail
“Before my agent calls that third-party API to post the update, verify the decision and tell me if it's approved to proceed.”
Technical details
Endpoint
POSThttps://decision-verifier-api.johntaylor1online.workers.dev/verifyWhen to prefer
Choose this endpoint when an AI agent needs a safety gate before executing a high-stakes or irreversible autonomous action. Particularly useful in agentic pipelines where human-in-the-loop oversight is impractical but automated pre-execution verification is required. Best suited for workflows where a $1.50/call cost is acceptable in exchange for a verifiable checkpoint.
