AgentResolver

Know when AI agents can no longer discover, call, or pay your service.

AgentResolver continuously checks the machine-facing parts of a public API, MCP server, x402 service, or agent product. Capture a free snapshot now, then use managed monitoring to detect compatibility, tool-contract, and payment-contract drift after launch.

Run a free monitoring snapshot $19 / 30-day managed monitoring

Catch compatibility drift

Re-check the public origin, discovery files, OpenAPI surface, security signals, and optional live MCP handshake instead of assuming yesterday's integration still works.

Fingerprint the MCP contract

AgentResolver can initialize the real MCP endpoint, list its tools, and fingerprint the exposed tool contracts so tool/schema changes become measurable drift.

Watch x402 payment terms

For GET-safe paid routes, monitor HTTP 402 behavior, network, asset, payTo recipient, amount, resource binding, and TLS without holding wallet keys or authorizing spend.

The monitoring contract

POST /api/service-monitor
Content-Type: application/json

{
  "label": "Example API",
  "origin": "https://api.example.com",
  "mcpEndpoint": "https://api.example.com/mcp",
  "x402Endpoint": "https://api.example.com/paid"
}

Need to make the service agent-readable first?

The existing Agent Distribution Pack remains available to diagnose discovery gaps and generate launch artifacts. It is now supporting the monitoring product rather than being the company's only commercial bet.

POST /api/agent-distribution-pack
Content-Type: application/json

{
  "providerName": "Example API",
  "description": "Current structured data for autonomous agents.",
  "origin": "https://api.example.com",
  "mcpEndpoint": "https://api.example.com/mcp"
}

Agent Distribution

Route existing x402 verify + settle traffic through AgentResolver.

Existing sellers can point their facilitator client at https://agentresolver.vercel.app. AgentResolver exposes the standard /supported, /verify, and /settle surface, measures real routed settlement volume, and fails closed when settlement state is ambiguous instead of blindly retrying.

Use the reliability router

Verify-before-pay remains available for autonomous buyers.

Buyer agents can still live-check payTo, quoted price, network, asset, resource binding, TLS, and reachability before signing.

POST /api/x402-payment-preflight
Content-Type: application/json

{
  "url": "https://merchant.example/api",
  "method": "GET",
  "maxPriceUsd": 0.01
}

AgentResolver itself is callable over MCP.

Hosted endpoint: https://agentresolver.vercel.app/mcp. Free monitoring/discovery surfaces stay free; priced tools disclose their x402 USDC price before execution and require caller-controlled payment authorization.
