About This Tool

Zepto API Tester provides a programmatic way to validate endpoints and performance. It supports HTTP methods, headers, query params, and optional bodies, enabling deterministic checks for defined environments. It is aimed at developers and QA engineers who need reliable, repeatable results during API development and integration. The tool emphasizes clear pass/fail signals, latency measurement, and optional schema validation to enforce contract accuracy.
With configurable inputs and reusable test patterns, teams can embed checks into CI pipelines or local workflows to catch regressions early.
It benefits backend teams, frontend teams consuming APIs, and DevOps engineers responsible for API reliability by providing concise, structured feedback and exportable results for dashboards and audits.

Frequently Asked Questions

Find Quick Answers

What can Zepto API Tester validate?

Zepto API Tester validates endpoints by checking the HTTP status, analyzing the response body, and optionally validating it against a provided JSON schema. It also reports latency and supports environment-specific checks to ensure consistent behavior across stages.

Can I use it in CI pipelines?

Yes. Results export as JSON and can be integrated with CI tooling. You can parameterize inputs, run in headless mode, and publish pass/fail status to dashboards.

Where is data stored?

Test inputs and results are stored transiently in memory during a session; you can export to JSON for archival or downstream processing; no automatic retention is performed without explicit export.

Does it handle authentication?

It accepts authentication tokens or credentials via headers or environment variables provided by the user. It does not perform OAuth flows or manage credentials by itself.
