Can I test authenticated API endpoints?

Yes. Add Authorization headers (Bearer token, API key, Basic auth) in the request headers field. Credentials are encrypted in transit and never stored.

What is the difference between API Deep-Scan and a regular health check?

A health check only verifies the endpoint returns 200 OK. API Deep-Scan validates the full response: correct status code, response body structure, header values, CORS configuration, authentication, and performance from multiple regions.

Can I test GraphQL APIs?

Yes. Set method to POST, Content-Type to application/json, and include your GraphQL query in the request body.

Free Tool — No Signup Required

Free API Deep-Scan

Go beyond status codes. Test your API endpoint for correct response body, headers, authentication, rate limits, and performance from global locations.

This API health check tool evaluates endpoint reliability beyond status codes by inspecting timing, response behavior, and protocol-level consistency. It helps teams identify fragile API behavior before downstream integrations fail in production. The output is structured for engineering triage and release validation, making it useful during deploy checks and post-incident analysis. For critical services supporting checkout, login, and automation workflows, this provides practical reliability signal where basic ping checks are insufficient.

What this tool detects

Slow or unstable API response behavior
Header and protocol-level misconfigurations
Inconsistent endpoint responses under normal load

Q: How is this different from a basic API ping?

A: A ping confirms reachability. Deep-scan evaluates response quality and reliability behavior that determines whether integrations keep working.
