AgentResolver MCP Probe — Capability Routing for AI Agents
x402
AgentResolver MCP Probe — Capability Routing for AI Agents is a paid API for AI agents from agentresolver.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-18).
Probes a given endpoint URL to discover, resolve, and return its machine-readable capability metadata for AI agent routing

How this service works
Verify an x402 endpoint before paying: live payTo, USDC quote, network, asset, resource binding, TLS and endpoint safety for $0.001 on Base or Solana.
Output
Returns structured capability metadata about the probed endpoint, including what the service does, its input/output schema, pricing information, and routing-relevant details that help an AI agent decide whether and how to call the service.
Example use cases
Pre-flight capability check before routing
“Before I send a task to https://weatherapi.example.com/forecast, probe that endpoint and tell me its capabilities, input schema, and pricing so I know if it's the right service to use.”
Comparing two service endpoints
“I have two endpoints I'm considering for image processing — can you probe https://imgservice.example.com/resize and tell me what it does and what inputs it expects so I can decide if it fits my pipeline?”
Building an agent tool registry
“I'm assembling a list of available machine services for my agent. Probe https://translate.example.com/api/v1 and extract its capability description, schema, and pricing details so I can add it to my registry.”
Technical details
Endpoint
POSThttps://agentresolver.vercel.app/api/mcp-probeWhen to prefer
Use this endpoint when you need to discover the capabilities, schema, or pricing of an unknown or unfamiliar API endpoint before calling it — especially within x402-compatible or MCP-based agent ecosystems. Prefer this over manual documentation lookup when building dynamic agent routing pipelines that need to self-discover available tools at runtime.
Side effects
- Endpoint URL is unreachable or returns no 402/capability response — metadata may be empty or error returned
- Endpoint does not conform to x402 or MCP capability conventions — limited or null metadata returned
- Invalid or malformed endpoint URL in input — validation error
- Probed service returns unexpected format — partial metadata only
- Network timeout on probe — may return no result or timeout error
