The 2 AM Slack Message That Started Everything

“Hey, does anyone have that curl command for creating a Stripe customer? The one that actually works?”

If you’ve ever sent or received this message, you know the pain. This was our team six months ago, frantically searching through Slack history, bash history, and three different Postman collections to find a working API call that we had definitely used last week.

That night, after finally finding the command buried in a colleague’s DM from two months prior, we realized: we’re all solving the same problem, badly, over and over again.

The Reality of Modern API Development

Let me paint you a picture of what API integration actually looks like in 2025:

Monday Morning: The Onboarding

New Developer: "How do I test our payment integration?"
Senior Dev: "Oh, check the Postman collection... wait, that's outdated.
            Let me send you my curl commands... actually, check this
            Slack thread from March. No wait, the API changed since then..."

Tuesday Afternoon: The Parameter Hunt

# Terminal history from actual debugging session
curl -X POST https://api.stripe.com/v1/customers -d email="test@test.com"
# Error: missing required field

curl -X POST https://api.stripe.com/v1/customers -d email="test@test.com" -d description="Test"
# Error: invalid authentication

curl -X POST https://api.stripe.com/v1/customers -H "Authorization: Bearer sk_test_..." \
  -d email="test@test.com" -d name="Test User"
# Error: 'name' should be 'full_name'

# 20 minutes later...
curl -X POST https://api.stripe.com/v1/customers -H "Authorization: Bearer sk_test_..." \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "email=test@test.com&description=Test"
# Finally works!

Wednesday Crisis: The Production Incident

Team Lead: "Why is the integration failing in production?"
Developer: "It works on my machine with my test keys..."
DevOps: "The staging environment uses different headers..."
Team Lead: "Does anyone have the production curl command?"
Everyone: *nervous silence*

Thursday Code Review: The Security Nightmare

// Found in git history
API_KEY = "sk_live_4aGh9..."  // TODO: move to env vars

Friday Retrospective: The Same Problems, Again

  • “We need better API documentation” (we have a 5000-line OpenAPI spec)
  • “We should standardize our testing approach” (we’ve tried three times)
  • “Let’s update the Postman collection” (last updated: 8 months ago)

The OpenAPI Paradox

Here’s the irony that kills me: we already have everything we need.

Every modern API comes with an OpenAPI specification - a complete, machine-readable description of every endpoint, parameter, and response. Stripe’s OpenAPI spec? 300+ operations, perfectly documented. GitHub’s? 600+ endpoints, all specified.

But what do we do with these specs? We upload them to documentation generators that create pretty, non-executable web pages. We have the blueprint, but we’re still building with sticks and stones.

The Breakthrough Moment

One night, after helping the third developer that week find “that working customer creation command,” we had a realization:

What if the OpenAPI spec WAS the CLI?

Not documentation about the API. Not a web page showing the API. But an actual, executable command-line tool generated instantly from the spec.

Enter mrapids: Your API Spec, Now Executable

Here’s what that same Monday-to-Friday looks like with mrapids:

Monday Morning: Instant Onboarding

New Developer: "How do I test our payment integration?"
Senior Dev: "Run these two commands:"

mrapids init stripe --from-url https://raw.githubusercontent.com/stripe/openapi/master/openapi/spec3.yaml
mrapids list --filter customer

# New dev is productive in 2 minutes, not 2 days

Tuesday Afternoon: No More Parameter Guessing

# Need to create a customer but forgot the parameters?
mrapids show CreateCustomer
# Shows exact parameters, types, and requirements

# Still unsure? Generate a template
mrapids run CreateCustomer -i
# Creates a perfect JSON template with examples

# Run it
mrapids run CreateCustomer --file customer.json
# ✅ Success - first try, every time

Wednesday Crisis: Environment Clarity

# Each environment has its own (git-ignored) credentials
.mrapids/envs/
├── .env.development    # Local testing
├── .env.staging       # Staging API keys
└── .env.production    # Production keys (never in git)

# Test in production (safely)
mrapids run GetCustomer --id cus_123 --env production --dry-run
# See exactly what would be sent, without sending it

Thursday Code Review: Zero Hardcoded Secrets

# No keys in code, ever
export STRIPE_API_KEY="sk_test_..."
mrapids run CreatePayment --env development

# Git history is clean
git grep "sk_" --all
# No results. Beautiful.

Friday Retrospective: Actual Progress

# Save successful workflows
mrapids run CreateCustomer --file customer.json --save-to-collection

# Share with team (it's just YAML)
git add .mrapids/collections/customer-onboarding.yaml
git commit -m "Add customer onboarding test suite"

# Everyone can run it
mrapids collection run customer-onboarding --env staging

The Real Problems We’re Solving

1. The Discovery Problem

Before: “What endpoints exist? Let me search this 5000-line YAML file…”
After: mrapids list --filter payment → Instant results

2. The Memory Problem

Before: “Was it ‘customer_email’ or ‘email’ or ‘customerEmail’?”
After: mrapids run CreateCustomer -i → Perfect template every time

3. The Environment Problem

Before: Hardcoded URLs and keys scattered across scripts
After: --env production → Right config, every time

4. The Sharing Problem

Before: “Check my Postman collection… oh, you need a license”
After: Git-controlled YAML collections, free forever

5. The Validation Problem

Before: “Let’s try this in production…” breaks everything
After: --dry-run --as-curl → See before you send

The Developer Experience Revolution

Here’s what actually changes when you adopt mrapids:

Week 1: Individual Productivity

  • API exploration time: 30 minutes → 30 seconds
  • First successful API call: 15 attempts → 1 attempt
  • Finding the right endpoint: Documentation diving → one command

Week 2: Team Collaboration

# Your API tests are now code
name: Customer Lifecycle Tests
requests:
  - name: Create Customer
    operation: CreateCustomer
    save_as: new_customer
    
  - name: Add Payment Method
    operation: AddPaymentMethod
    params:
      customer_id: "{{ new_customer.id }}"

Week 3: CI/CD Integration

# .github/workflows/api-tests.yml
- name: Run API Integration Tests
  run: |
    mrapids collection run integration-tests --env staging --fail-on-error

Month 2: Organizational Impact

  • Onboarding time: 2 weeks → 2 hours
  • API-related bugs: Down 80%
  • Postman licenses: $200/month → $0

The Technical Innovation

What makes mrapids different isn’t just better UX - it’s a fundamental rethinking of how we interact with APIs:

  1. The spec IS the interface - No translation layer, no outdated docs
  2. Everything is executable - If it’s in the spec, you can run it
  3. Git-native workflow - Collections, configs, and tests are all version-controlled YAML
  4. Zero-installation for APIs - One command turns any OpenAPI spec into a CLI

The Philosophy: Make the Right Thing the Easy Thing

We built mrapids with one core belief: developers already have everything they need in the OpenAPI spec - they just need a better way to use it.

We’re not adding another layer of abstraction. We’re not creating another standard. We’re simply making what already exists actually useful.

Try It Yourself - 60 Seconds to “Aha!”

# Install
npm install -g mrapids

# Pick any API you work with
mrapids init github --from-url https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.yaml

# Discover
mrapids list --filter repo

# Understand
mrapids show repos/get

# Execute
mrapids run repos/get --param owner=microsoft --param repo=vscode

In 60 seconds, you just went from zero to successfully calling the GitHub API. No documentation diving, no parameter guessing, no authentication struggles.

The Future We’re Building

Imagine a world where:

  • Every API is instantly executable via CLI
  • API tests are just YAML files in your repo
  • Onboarding a new developer takes minutes, not weeks
  • Breaking changes are caught before deployment
  • API integration is boring because it just works

This isn’t a dream - it’s what hundreds of teams are already experiencing with mrapids.

The Bottom Line

We built mrapids because we were tired of solving the same problem every day. Tired of searching for that working curl command. Tired of explaining API authentication to new developers. Tired of maintaining outdated Postman collections.

If you’ve ever thought “there has to be a better way” while wrestling with an API, you’re right. There is.

Your OpenAPI spec is more than documentation. With mrapids, it’s your new command-line superpower.
