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/paywall-scanner)
Output
Returns a structured compliance report covering JSON-RPC validity, measured latency against SLA thresholds, OpenAPI schema conformance, and HTTP 402 / x402 settlement header presence and correctness for the target URL.
Example use cases
Verify MCP server before deploying
“Before I add this MCP server at https://tools.mycompany.ai/mcp to my agent swarm, can you audit it for JSON-RPC compliance and check if its latency meets SLA standards?”
Check x402 paywall configuration
“I've set up a paywall at https://api.startup.io/v1/premium — can you scan it to confirm the HTTP 402 settlement headers are correctly configured for x402?”
Ongoing A2A endpoint compliance check
“Can you run a compliance audit on https://agent.partner.com/a2a and tell me if their OpenAPI schema is valid and if they're passing all the protocol checks?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/paywall-scanner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that a remote A2A agent, MCP server, or x402 paywall URL correctly implements JSON-RPC, meets latency SLAs, exposes a valid OpenAPI schema, and has proper HTTP 402 settlement headers — especially before onboarding a third-party agent into a swarm or before going live with a paid API endpoint.
Side effects
- Target URL is unreachable or times out — returns connectivity error
- Invalid or malformed URL input — returns validation error
- Target endpoint does not expose expected protocol headers — reports non-compliance
- Rate limiting or auth errors on the target endpoint prevent full audit
- Ambiguous or incomplete OpenAPI schema at target causes partial results
