How this service works
Pre-execution decision API for autonomous agents with paid risk scoring, simulation, and policy-gate endpoints using x402 V2.
Output
Returns a risk score, policy gate decision (allow/block), and optionally a simulation result showing predicted outcomes of the action, enabling the calling agent to decide whether to proceed with execution.
Example use cases
Financial transaction safety validation
“Before my agent processes this wire transfer request from a customer, I need you to run a risk score and policy check — it's for $50,000 to a new international account they just added, so I want to know if there are any red flags or if we should block it outright.”
Autonomous trading action pre-flight check
“My trading agent wants to execute a large position liquidation in the next few seconds — can you simulate what would happen if it goes through, score the risk level, and tell me whether our compliance policies would allow it or if I should stop it.”
Database deletion safety gating
“An automation agent is about to delete customer records matching certain criteria as part of a data cleanup task — before it actually runs the deletion, can you evaluate whether this action passes our safety policies and give me a risk assessment of potential issues.”
Technical details
Endpoint
POSThttps://api.actiongate.xyz/docsWhen to prefer
Use ActionGate when you need a pre-execution safety layer for autonomous agent actions — especially in high-stakes or financial contexts where you want risk scoring, policy enforcement, and simulation before allowing an agent to proceed. Prefer this over post-hoc logging or monitoring when preventing bad actions is more important than observing them.
Side effects
- Invalid or malformed action payload returns 400 with validation error
- Policy configuration not found returns 404
- Risk scoring engine timeout returns 503
- Insufficient context for simulation returns partial result with low-confidence flag
- Payment/authentication failure on x402 returns 402 or 401
