How this service works
Continuously check whether AI agents can discover, call and pay your API, MCP server or x402 service. Free live checks and GitHub Action monitoring.
Output
Returns a JSON object indicating the health status of the monitored endpoints across agent discoverability, callability, and payment readiness dimensions, covering the configured API origin, MCP server, and x402 endpoint over a 30-day monitoring window.
Example use cases
Monitoring a new x402-enabled SaaS API
“I just launched my x402-enabled API at https://api.myproduct.com and my x402 payment endpoint at https://api.myproduct.com/pay — can you set up a 30-day monitor called 'MyProduct API Health' so I get continuous checks that AI agents can discover and pay it?”
Keeping an MCP server agent-accessible
“Can you start a 30-day health monitor labeled 'Dev MCP Server' for my MCP server at https://mcp.devtools.io to make sure AI agents can always connect and call it?”
Pre-launch agent-commerce readiness check
“Before I announce my new agent marketplace listing, can you set up a managed 30-day monitor called 'Marketplace Launch Check' on my API origin https://launch.agentapp.xyz and x402 endpoint https://launch.agentapp.xyz/x402 to confirm everything stays healthy for agents?”
Technical details
Endpoint
POSThttps://agentresolver.vercel.app/api/managed-monitor-30d?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ongoing, automated 30-day health monitoring of an AI agent-facing API, MCP server, or x402 payment endpoint — particularly when you want continuous assurance that agents can discover, call, and pay your service rather than a single one-off check. Prefer the x402 Payment Preflight endpoint for a one-time pre-payment verification of a single x402 endpoint.
Side effects
- Invalid or unreachable origin/MCP/x402 URL returns an error indicating the endpoint could not be reached
- Malformed URL (not matching https:// pattern) causes a validation error
- Missing all optional endpoint fields may result in an empty or partial health report
- Service unavailability on the monitored endpoint may cause check failures reported in the result
- Label exceeding 120 characters is rejected by schema validation
