How this service works
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. (Live x402 v2, IETF MPP & MCP endpoint at https://workflows.agentdiet.dev/v1/preflight)
Output
Returns a structured compliance report covering JSON-RPC protocol validity, measured latency against SLA thresholds, OpenAPI schema detection, and HTTP 402 / x402 v2 settlement header presence and correctness for the target URL.
Example use cases
Preflight check before swarm integration
“Before I wire this MCP server at https://tools.myplatform.ai/mcp into my agent swarm, can you audit it for JSON-RPC compliance, latency SLA, and x402 HTTP 402 payment header support?”
Validating x402 payment headers on a monetized API
“I'm building a monetized agent endpoint at https://api.agentservice.io/v1/run — can you check if it correctly exposes HTTP 402 settlement headers and passes the x402 v2 compliance checks?”
SLA and schema audit for a third-party A2A agent
“We're evaluating a third-party A2A agent at https://partner.agentco.dev/a2a before signing an SLA — can you audit it for JSON-RPC validity, OpenAPI schema presence, and latency compliance?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a rapid, single-call compliance preflight on any A2A agent, MCP server, or x402-monetized URL before connecting it to an agent swarm or signing an SLA. It is specifically designed for agent-to-agent and machine-to-machine protocol validation (JSON-RPC, IETF MPP, x402 v2) rather than generic HTTP health checks or uptime monitors.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Target URL does not respond to expected protocol probes — returns non-compliant status
- Invalid or missing URL parameter — returns 400 bad request
- Target service returns unexpected content type — schema check fails
- x402 headers absent or malformed — flagged as non-compliant in report
