# A2A, MCP & HTTP 402 Endpoint SLA Compliance Auditor

> A2A, MCP & HTTP 402 Endpoint SLA Compliance Auditor is a paid API for AI agents from sec-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Audits a remote agent, MCP, or x402 URL for JSON-RPC compliance, latency SLA, OpenAPI schema validity, and HTTP 402 payment settlement headers

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sec-intel-agentdiet-dev-a2a-mcp-http-402-endpoint-sla-compliance-f629a728
```

Example prompt: Can you audit https://my-agent.example.com/mcp for JSON-RPC compliance, latency SLA, and HTTP 402 payment header correctness so I know if it meets MCP and x402 standards?

## When to prefer this

Choose this endpoint when you need to programmatically verify that a remote A2A agent, MCP server, or x402-enabled service meets protocol compliance standards — specifically JSON-RPC spec adherence, latency SLAs, OpenAPI schema correctness, and HTTP 402 payment headers. Prefer it over general uptime monitors or health-check tools when protocol-level compliance (not just availability) is required, especially in x402/MCP/A2A ecosystems.

## Known failure modes

- Target URL is unreachable or returns a network error — audit fails with connectivity error
- Target URL is not a valid A2A/MCP/x402 endpoint — may return partial or empty compliance results
- Malformed or missing URL parameter — returns 400 bad request
- Target endpoint has auth requirements that block the probe — audit results may be incomplete
- Timeout if target service is slow beyond SLA threshold — latency failure is itself a finding

## 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://sec-intel.agentdiet.dev/v1/mcp-security-scan)

## Output

Returns a structured audit report covering: JSON-RPC protocol compliance status, latency SLA measurements, OpenAPI schema validity findings, and HTTP 402/x402 settlement header compliance — all for the submitted target URL.
