API monitoring that catches a broken endpoint before your app does
Uptura calls your REST and GraphQL endpoints on a schedule, asserts the status code, latency, and response body are right, and alerts your team the instant one fails — no more finding out from a support ticket.

Why it matters
Your app is only as reliable as its APIs
Modern products are held together by API calls, and when one breaks the failure is invisible from the outside. API monitoring watches each endpoint's status, speed, and response so you catch the problem before it cascades through your app.
Silent
is how APIs fail
A broken API rarely shows a down homepage. The app just stops working — logins hang, data won't load — and nobody sees a red light.
200 OK
can still be wrong
An endpoint can return a healthy status code with an empty or malformed body. Only asserting on the response catches that kind of failure.
Latency
breaks UX first
APIs rarely go from fast to down. They get slow first — and slow endpoints degrade every screen that depends on them long before they error.
What we monitor
Everything an API monitoring tool should do
Uptura goes past a simple ping — checking that each endpoint is up, fast, and returning exactly the response your integrations expect, with alerts the moment it doesn't.
Endpoint status & uptime
Call every REST or GraphQL endpoint on a schedule as tight as 60 seconds and confirm it's reachable — so a broken API is caught before your app or your customers hit it.
Response-time & latency tracking
Track latency for each endpoint over time, so you can see an API getting slower and fix it long before slow responses turn into timeouts and errors.
Status code & body assertions
Assert on status codes, response time, headers, and JSON body values — so a 200 that returns the wrong payload still counts as a failure, not a pass.
Authenticated & multi-step calls
Send custom headers, tokens, and request bodies, and chain calls together — so you can monitor endpoints behind auth and whole API workflows, not just public health checks.
Schema & payload validation
Validate that responses still match the shape your integrations expect, so a breaking change upstream is caught the moment the contract shifts.
Instant multi-channel alerts
The moment an endpoint fails a check or breaches a latency threshold — and again when it recovers — your team is notified over email, Slack, or Discord.
How it works
Add an endpoint, watch it around the clock
API monitoring should take a minute to set up. Give Uptura the endpoint and what a good response looks like, and it handles the checking from there.
- 1
Add your endpoints
Point Uptura at the REST or GraphQL endpoints you depend on, with any headers, tokens, or request bodies they need. No agents to install.
- 2
We call and verify them
Uptura hits each endpoint on a schedule from multiple regions, measuring response time and asserting the status code and payload are actually correct.
- 3
You get alerted the second it breaks
When an endpoint errors, returns the wrong response, or slows past your threshold, your team is notified — with the failing assertion and a recovery notice when it clears.
One platform
APIs are just one signal Uptura watches
A healthy API doesn't help if the site is down, the certificate expired, or the checkout is broken. Uptura pairs API monitoring with uptime, SSL, DNS, SEO, performance, and more — so every part of a website's health lives in one dashboard and one alert stream.
Uptime Monitoring
Minute-by-minute checks from multiple regions catch outages the instant they happen — before your customers do.
SSL & Domain
Track SSL certificate, issuer, and domain expiry across every site, with alerts well before anything lapses.
DNS Monitoring
Watch DNS records for unexpected changes, misconfigurations, and propagation issues in real time.
SEO Monitoring
Catch metadata, canonical, robots.txt, and sitemap regressions that quietly tank rankings — the moment they ship.
Core Web Vitals
Track LCP, CLS, and INP over time with Lighthouse scans, and get alerted when performance regresses.
Synthetic & Forms
Run scripted checks on logins, checkouts, and contact forms so broken user journeys never go unnoticed.
Visual RegressionSoon
Capture daily screenshots and highlight visual differences between deployments before anyone else spots them.
Accessibility
Continuous WCAG and Axe scans with historical reports, so accessibility regressions get caught — not shipped.

FAQ
API monitoring, answered
What is API monitoring?
API monitoring is the practice of continuously calling your API endpoints to confirm they're available, fast, and returning the correct response. A monitoring tool sends requests on a schedule, checks the status code, latency, and body against your expectations, and alerts you the moment an endpoint fails — so you catch API problems before they break the apps that depend on them.
How is API monitoring different from uptime monitoring?
Uptime monitoring confirms a URL responds. API monitoring goes deeper: it sends real requests — often with authentication and request bodies — and asserts on the status code, response time, and JSON payload. A homepage can be up while a critical API returns errors or the wrong data, which is exactly what API monitoring catches. Uptura offers both from the same dashboard.
Can you monitor REST and GraphQL APIs?
Yes. Uptura can call REST and GraphQL endpoints with custom methods, headers, tokens, and request bodies, then assert on the response. That means you can monitor public health checks and authenticated, parameterized endpoints alike.
What API metrics can I track?
Uptura tracks availability, response time and latency, status codes, and whether the response body matches what you expect. Over time you get uptime percentages and latency trends per endpoint, so you can spot degradation early and prove reliability to the teams that depend on your API.
Can I monitor endpoints that require authentication?
Yes. You can attach headers, bearer tokens, API keys, and request bodies to each check, and chain calls so one response feeds the next. That lets Uptura monitor endpoints behind auth and multi-step API flows, not just open health endpoints.
Is there a free API monitoring tool?
Several tools offer limited free API monitoring for a handful of checks. Uptura is launching API monitoring as part of a complete website operations platform — join the waitlist for early access and founding-user pricing when it goes live.
