Runs a list of HTTP checks against a base URL from a JSON file and reports status codes, response time and body assertions. Use when the user asks whether an API is up, wants a smoke test after a deploy, or needs to verify that endpoints return what the docs promise.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API endpoint tester
A tiny smoke test runner with no dependencies. It sends real HTTP requests, so only point it at services
the user owns or has permission to test.
## When to use
- After a deploy, to confirm the main endpoints respond.
- When the user suspects an endpoint changed shape or status code.
- To turn a list of curl commands into a repeatable check.
## How to run
```bash
python scripts/check_api.py checks.json --base-url https://staging.example.com
```
The checks file is a JSON list:
```json
[
{"name": "health", "method": "GET", "path": "/health", "expect_status": 200, "expect_body_contains": "ok"},
{"name": "create", "method": "POST", "path": "/items", "json": {"name": "demo"}, "expect_status": 201}
]
```
Optional fields: `headers` (object), `json` (request body), `expect_status` (default 200),
`expect_body_contains` (string) and `timeout` (seconds, default 10).
## Output
JSON with `base_url`, `passed`, `failed` and `results`. Each result has `name`, `ok`, `status`,
`elapsed_ms` and, when it failed, a `reason`. The exit code is 1 when any check fails.
## After running
…Read the whole file at its exact version.
How to install
mdr add lethe044/agentskill-kit/api-endpoint-tester@sha256:12c706ae50587be2The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
