How this service works
TLS certificate inspection API for agents: inspect issuer, subject, SANs, and expiry for one HTTPS host for $0.01 USDC before an agent trusts the channel.
Output
Returns structured TLS certificate data including the issuer organization and CA, subject common name, list of Subject Alternative Names (SANs), certificate validity period with expiry date, and an assessment of renewal risk — e.g. days remaining and whether renewal action is recommended.
Example use cases
Audit certificates before partnership outreach
“Before we reach out to potential partners, can you check the TLS certificates for all these domains and flag any that are issued by untrusted CAs or expiring within the next 60 days?”
Monitor infrastructure for expiring certs
“I need to monitor our production domains for certificate expiry risk. Can you check the TLS status for api.prod.company.com, app.prod.company.com, and cdn.prod.company.com, and let me know which ones need renewal soon?”
Verify domain security during intake
“When we onboard new client domains, I want to verify their certificate setup is trustworthy. Can you inspect the TLS certificate for their domain and confirm the issuer, covered SANs, and whether renewal is imminent?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/tls-inspectWhen to prefer
Use this endpoint when you need to programmatically audit TLS certificate health for a specific domain — especially for pre-outreach trust checks, compliance validation, infrastructure monitoring, or flagging certificates nearing expiry. Prefer this over manual browser inspection when you need structured, machine-readable certificate metadata in an agentic workflow.
Side effects
- Domain does not have a reachable HTTPS endpoint — connection timeout or refused
- Invalid or malformed hostname input — validation error returned
- Self-signed or untrusted certificate — may return partial data with trust warning
- Certificate already expired — returned with zero or negative days remaining
- Domain resolves but TLS handshake fails — handshake error response
