x402
X402-BROKER Audit Endpoint (agentdiet.dev) is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).
Audits an HTTP endpoint URL to verify its x402/MCP/A2A compliance, returning structured audit data and compression ratio proof-of-work metadata.

How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a 'status' field ('ok' on success), a nested 'data' object containing audit findings, and a 'roi_proof' object including a 'compression_ratio_pct' value (e.g. 91.4%) representing the efficiency metric of the audited endpoint.
Example use cases
Pre-integration x402 compliance check
“Before I integrate this new MCP server into my agent pipeline, can you audit https://mcp.example.com/tools via GET to confirm it's properly x402-compliant and show me the audit results?”
Verify A2A agent endpoint before payment
“I want to make sure the agent at https://agentapi.example.com/a2a supports x402 before sending it USDC — can you run an audit on that GET endpoint and tell me if it passes?”
Compression proof validation for a broker API
“Can you check the compression ratio proof for https://broker.example.com/v1/query using a GET request and tell me what the audit data shows?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/x402-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, proof-of-work-backed audit of whether a specific HTTP endpoint conforms to x402, MCP, or A2A protocols, especially when you need a compression ratio ROI proof as part of the verification. Prefer this over manual inspection or generic HTTP checkers when integrating paid agent-to-agent pipelines settling in USDC on Base.
Side effects
- Target URL is unreachable or returns non-200 — audit may fail or return incomplete data
- Missing required 'type' or 'method' fields in input — returns schema validation error
- URL not x402-compliant — audit completes but findings indicate non-conformance
- Payment not settled in USDC on Base — request rejected before audit executes
- Invalid HTTP method enum value — request rejected with input validation error
