x402
AION Agent Assurance Gateway – Endpoint Verify is a paid API for AI agents from agents.aiserviceco.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).
Verifies that a given MCP, A2A, or API endpoint is correctly implemented and publicly reachable, returning a structured JSON verification report with pass/fail checks and signed evidence.

How this service works
x402-paid read-only MCP/A2A/API endpoint verification and robots.txt-respecting web page reading, returning JSON. Paid with x402 (exact scheme, USDC on Base). Release status: production acceptance of this build is not asserted, and a historical review of 6f14c11d does not accept this candidate. Page-read: one owner-funded test payment settled on Base; verify: settlement unproven; organic demand remains unproven; no independent-buyer acceptance, paid-use, or revenue claim.
Output
A JSON object containing: a top-level verdict (PASS/FAIL), a list of individual named checks each with status and detail, an array of evidence records (URL, step, HTTP method, status code, request/response SHA-256 hashes, byte counts), the protocol checked, a checkedAt ISO timestamp, and an evidenceDigest for tamper-evident audit trail. Schema version is aion.verify.v1.
Example use cases
Pre-launch MCP server readiness check
“Before I list my MCP server in a marketplace, can you verify that https://myagent.example.com/mcp is passing all MCP protocol checks — initialize, tools/list, and public reachability?”
Third-party A2A endpoint audit
“I'm about to integrate a vendor's A2A endpoint at https://partner.example/a2a into my pipeline — can you run a verification check on it using the a2a protocol and show me the detailed results?”
CI/CD API endpoint conformance gate
“After my latest deployment, please verify that https://api.myservice.io/v2 is up and conformant using the api protocol, and give me the verdict and evidence digest so I can log it.”
Technical details
Endpoint
POSThttps://agents.aiserviceco.com/paid/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, evidence-backed compliance report for an MCP, A2A, or REST API endpoint — especially before listing an agent service in a marketplace, integrating a third-party agent, or running automated conformance gates in CI/CD. Prefer this over generic uptime monitors when you need protocol-level checks (e.g. MCP initialize + tools/list) and cryptographically signed evidence records rather than just HTTP reachability.
Side effects
- Target URL is unreachable or returns non-200 — checks will FAIL with detail explaining the HTTP error
- Invalid protocol enum value — request rejected with validation error
- URL does not match the required http/https pattern — schema validation error
- Target endpoint violates robots.txt — verification may be skipped or partial
- Payment via x402/USDC on Base not settled — request not processed
- Endpoint responds but does not conform to protocol (e.g. missing protocolVersion) — individual checks FAIL with specific detail
