## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability company-enrich-agentdiet-dev-a2a-mcp-http-402-endpoint-sla-compliance-7db6caf2
```

Example prompt: Can you audit https://myagent.example.com/mcp for JSON-RPC compliance, latency SLA, and HTTP 402 payment header support?

## When to prefer this

Use this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled service meets protocol compliance standards before integration, deployment, or marketplace listing. Prefer this over manual inspection when you need structured, machine-readable audit results covering JSON-RPC, OpenAPI, latency SLA, and HTTP 402 header compliance in a single call.

## Known failure modes

- Target URL is unreachable or returns a network error — audit fails with connectivity error
- Target URL is not an A2A/MCP/x402 endpoint — compliance checks may all fail or return not-applicable
- Invalid or malformed URL input — returns validation error
- Target endpoint has slow response causing latency SLA timeout — latency check fails
- Target endpoint returns unexpected content type — JSON-RPC and OpenAPI checks cannot complete

## 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://company-enrich.agentdiet.dev/v1/bazaar-verifier)

## Output

Returns a structured compliance report including JSON-RPC protocol conformance status, measured latency against SLA thresholds, OpenAPI schema validation results, and HTTP 402 / x402 settlement header presence and correctness for the target URL.
