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
Returns a JSON object with a status field ('ok'), a data object containing certificate transparency records for the queried domain, and an roi_proof field showing compression efficiency metadata (e.g. compression_ratio_pct: 91.4).
Example use cases
Audit unexpected certificate issuance
“Check the certificate transparency logs for mycompany.com — I want to see if any certificates have been issued that I didn't authorize.”
Security review before domain handover
“Before we transfer ownership of acme-corp.com, can you pull the certificate transparency records so we can audit all TLS certs ever issued for that domain?”
Investigate phishing domain certificates
“I think someone registered a lookalike domain for phishing. Can you look up certificate transparency logs for login-mybank.com to see what certs have been issued?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/cert-transparency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, agent-native certificate transparency lookup that settles in USDC on Base via the x402 protocol — especially in agentic or automated pipelines where micropayment-per-query is preferred over API key subscriptions. It is well-suited for one-off certificate audits where you don't want to maintain a standing subscription to a CT log service.
Side effects
- Missing or invalid domain parameter returns an error response
- Domain with no certificate transparency records returns empty data
- Payment failure (insufficient USDC balance) blocks the request with HTTP 402
- Malformed input schema (missing required 'type' or 'method' fields) causes a validation error
- Upstream certificate transparency log service unavailability may result in timeout or empty response
