API testing & monitoring

Catch API problems
before your users do.

arrested.cloud is where you send ad hoc requests, watch service status on a schedule, turn requests into regression tests, and load-test your endpoints — all in one place, with every run recorded.

No credit card. No agent to install to get started.

Built for teams who'd rather find out from arrested.cloud than from a customer.

Everything in one place

Four ways to know your API works.

Start with a single request. Grow into scheduled monitoring, regression suites, and load tests — without switching tools.

Ad hoc REST calls

Build and fire off requests with a builder that handles headers, query params, environments, and {{templated}} variables. No bloat — just what it takes to move fast.

Service status, on schedule

Put any request or collection on a cadence — minutes, hours, or days — and get a live status feed the moment a response drifts out of the 2xx range, with email alerts you control.

Product testing

Attach validations to any request and group them into test collections. Run them on demand or on a schedule — every run's request, response, and pass/fail is recorded.

Performance evaluations

Run performance collections against your endpoints to see how they hold up under load — before a traffic spike finds out for you.

From zero to signal

How it works.

  1. 1

    Build a request

    Point at any endpoint, set headers, params, and payload, then save it to a locker so your team can find it.

  2. 2

    Organize into collections

    Group requests into request, test, or performance collections — whichever matches what you're trying to learn.

  3. 3

    Run it, or schedule it

    Fire it manually, put it on a recurring schedule, or wire it into your own automation.

  4. 4

    Get the report

    Every run is recorded — request, response, every validation, every processor — rolled up into a report you can read or email.

Full visibility

A record of every run — not just the last one.

Interactive runs and scheduled runs land in the same reports: full request/response snapshots, every validation with actual vs. expected, and an aggregate pass/warning/fail/error verdict per run and per collection over time.

  • Pass / warning / fail / error, ranked and rolled up automatically
  • Every validation's actual vs. expected value, kept — not just pass/fail
  • Email a report the moment a scheduled run finishes
