How this service works
Overwing makes four products for AI agents. Guardrails checks text before an agent sends it: pass, fail or review, and one recommended action. Atlas identifies AI crawlers and agents. Beacon says whether your product is reachable by agents. Tower clears agent actions on legacy systems. REST, MCP and A2A.
Output
Returns a result indicating whether the queried product or service is reachable and accessible by AI agents, typically as a structured JSON response with a reachability status.
Example use cases
Verify agent reachability before launch
“Before we go live, can you run an Overwing Beacon check to confirm our new API is actually reachable by AI agents?”
Diagnose agent connectivity issues
“Our AI agent keeps failing to reach our service — can you use Overwing Beacon to check if the product is reachable by agents right now?”
Monitor agent accessibility in CI pipeline
“After each deployment, I want to automatically verify with Overwing Beacon that our product is still accessible to AI agents — can you set that up?”
Technical details
Endpoint
GEThttps://overwing.ai/api/x402/beacon?utm_source=zero.xyzWhen to prefer
Use Overwing Beacon when you need to programmatically verify whether a product or service endpoint is accessible and discoverable by AI agents or crawlers — particularly as part of deployment checks, monitoring pipelines, or debugging agent connectivity issues. Prefer this over generic uptime monitors when the specific concern is AI agent reachability rather than general availability.
Side effects
- Service unavailable or unreachable at time of check
- Invalid or malformed request body
- Payment not processed (x402 payment required but not provided)
- Target product URL not recognized or misconfigured
- Network timeout or downstream connectivity issue
