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://whale-momentum.agentdiet.dev/v1/preflight)
Output
Returns a structured audit report covering JSON-RPC compliance status, latency SLA measurement, OpenAPI schema validation outcome, and HTTP 402 / x402 settlement header inspection for the supplied target URL.
Example use cases
Pre-deployment agent endpoint check
“Before I go live, audit https://staging.myagent.io/v1/agent and tell me if it passes JSON-RPC compliance, OpenAPI schema validation, and HTTP 402 header checks.”
x402 payment header verification
“I need to confirm that https://api.myservice.dev/tool is correctly returning x402 v2 settlement headers — can you run a compliance audit on it?”
SLA monitoring for third-party MCP tool
“Can you check the latency SLA and protocol compliance of the MCP server at https://tools.thirdparty.ai/mcp — I want to know if it meets acceptable response time thresholds.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled service URL correctly implements JSON-RPC, passes latency SLA thresholds, exposes a valid OpenAPI schema, and returns HTTP 402 payment settlement headers per the x402 v2 / IETF MPP spec — especially before deploying agents that will call those services or listing them in a registry.
Side effects
- Target URL is unreachable or times out — audit may return connectivity error
- URL does not expose a valid JSON-RPC or HTTP endpoint — compliance checks fail with no-response result
- Malformed or missing URL parameter returns a 400-level validation error
- Target service returns non-standard HTTP responses that prevent header inspection
- x402 settlement headers absent or malformed — reported as non-compliant without crashing the audit
