How this service works
Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.
Output
A JSON response containing the TLS/SSL certificate details for the queried host, including fields such as issuer, subject, subject alternative names, validity period (not-before/not-after), certificate chain, and fingerprint. The envelope also includes ok (boolean), utility name, requestId, and chargedCredits.
Example use cases
Check certificate expiry before deployment
“Before we push to production, can you check when the TLS certificate for checkout.mystore.com expires and who issued it?”
Audit third-party domain SSL health
“I need to verify the SSL certificate on partner-api.acmecorp.com — grab the cert details so I can confirm it's valid, not self-signed, and see all the SANs it covers.”
Security review of internal service
“Can you fetch the TLS certificate info for internal-auth.company.net and tell me the full chain, expiry, and fingerprint so I can log it for our security audit?”
Technical details
Endpoint
POSThttps://util.beauty/v1/net/certsWhen to prefer
Choose this endpoint when you need programmatic, pay-per-use TLS certificate inspection without managing your own OpenSSL tooling or a dedicated certificate monitoring service. Ideal for AI agents doing one-off security checks, pre-deployment audits, or enriching domain records with live certificate data. Prefer this over browser-based SSL checkers when you need structured JSON output suitable for downstream automation.
Side effects
- Host unreachable or connection refused — certificate cannot be fetched
- Domain does not exist (NXDOMAIN) — returns error or empty cert data
- Self-signed or untrusted certificate may return partial data or an error
- Invalid input hostname format — returns validation error
- Payment failure (insufficient USDC or API key balance) — 402 response, request not executed
- Timeout if remote host is slow to respond on port 443
