How this service works
One-shot health probe for any endpoint: HTTP status and latency, TLS certificate issuer and days-to-expiry, response size, security-header audit (HSTS, CSP, X-Content-Type-Options, X-Frame-Options) and named issues (SLOW_RESPONSE, CERTIFICATE_EXPIRING, SERVER_ERROR_STATUS). Call it on a schedule and you have uptime monitoring for a fraction of a cent.
Output
Returns a JSON object containing: `up` (boolean), `http_status` (integer), `latency_ms` (integer), `response_bytes` (integer), `checked_at` (ISO-8601 timestamp), `tls` object with `issuer`, `subject`, `valid_to`, `days_to_expiry`, and `sans`, `security_headers` object with boolean flags for `hsts`, `csp`, `x_frame_options`, and `x_content_type_options`, and an `issues` map listing any named problems such as SLOW_RESPONSE, CERTIFICATE_EXPIRING, or SERVER_ERROR_STATUS.
Example use cases
Pre-deployment endpoint sanity check
“Before I push this release, can you probe https://staging.myapp.com/api/v2/status and tell me the HTTP status, response time, and whether the TLS cert is going to expire soon?”
Security header audit for compliance
“I need to audit https://shop.example.com for missing security headers — can you check if it has HSTS, CSP, X-Frame-Options, and X-Content-Type-Options set?”
Scheduled uptime alert trigger
“Check https://payments.acme.io/health right now and flag it if the response is slow, the server returns an error status, or the certificate is about to expire.”
Technical details
Endpoint
POSThttps://agentbit.app/v1/monitor/endpointWhen to prefer
Use this endpoint when you need a single, instant health snapshot of a URL including TLS, latency, and security headers in one call. Prefer it over building custom monitoring logic when you want a cheap ($0.005/call), agent-friendly check you can schedule. It is especially valuable when you need TLS expiry and security-header auditing combined with basic uptime in a single round-trip rather than calling separate tools.
Side effects
- URL is unreachable or DNS fails — endpoint may return up:false with no latency data
- Invalid or non-HTTP/HTTPS URL — likely a 400-level error or validation failure
- Target URL returns no TLS (plain HTTP) — TLS fields will be absent or null
- Very slow target may cause a probe timeout — may surface as SLOW_RESPONSE issue
- Rate limiting or firewall on the target blocks the probe — may appear as a server error status
