# api-tester-cn

API testing and debugging toolkit — check endpoint status codes, validate JSON responses, lint for best practices (HTTPS, CORS, caching), compare two API responses, manage request templates, and export test history.

Commands

`check`

Test an API endpoint — shows HTTP status code, response time, content type, and server header.

scripts/script.sh check "https://api.github.com"

`validate`

Fetch a URL and validate the JSON response. Shows structure info (keys, types, array lengths).

scripts/script.sh validate "https://jsonplaceholder.typicode.com/posts/1"

`lint`

Check an API endpoint for best practices — HTTPS, CORS headers, content-type, rate limiting, and caching.

scripts/script.sh lint "https://api.example.com/v1/users"

`diff`

Compare JSON responses from two API endpoints side by side.

scripts/script.sh diff "https://api.v1.example.com/data" "https://api.v2.example.com/data"

`format`

Pretty-print JSON from a file or stdin.

scripts/script.sh format response.json
cat data.json | scripts/script.sh format

`convert`

Convert between JSON and CSV formats.

scripts/script.sh convert json2csv data.json
scripts/script.sh convert csv2json data.csv

`template`

Manage reusable request templates — save, list, and run API calls.

scripts/script.sh template list
scripts/script.sh template save "github-user" GET "https://api.github.com/users/octocat"
scripts/script.sh template run "github-user"

`report`

Generate a summary report of all tests run — counts by type, recent activity.

scripts/script.sh report

`recent`

Show the most recent test entries from history.

scripts/script.sh recent 20

`search`

Search test history by URL or keyword.

scripts/script.sh search "github"

`stats`

Show usage statistics — total requests, template count, date range.

scripts/script.sh stats

`export`

Export test history in json, csv, or txt format.

scripts/script.sh export json

`status`

Show tool status — version, data directory, entry count.

scripts/script.sh status

`help`

scripts/script.sh help

`version`

scripts/script.sh version

# Quick API health check
scripts/script.sh check "https://api.github.com"
