🔑 Key Improvements

1. Rate Limiting Documentation

Before: Inline code comments only
After: Complete guide with 10+ scenarios

Examples now cover:

• ✅ Within limit (multiple requests)
• ❌ Rate limit exceeded (429 response)
• ✅ Dedup reuse (no quota consumed)
• ❌ Different params (new job, quota consumed)
• ✅ In-progress reuse (within window)
• ❌ Outside dedup window (new job)

Each scenario shows:

• Request/response pair
• HTTP headers (RateLimit-*)
• Business outcome
• Time-based progression

2. Deduplication Explanation

Before: "System checks before creating new job"
After: Complete logic with examples

Now explains:

• Query logic (MongoDB find criteria)
• When dedup applies (ready or in-progress)
• When it doesn't (outside window, different params)
• Response flag ("reused": true)
• Rate limit impact (NOT consumed on dedup)

3. Customer Integration Guide

Before: Scattered across multiple docs
After: Single comprehensive reference

Includes:

• Architecture diagram
• Authentication (API key format, NOT Bearer token!)
• All 6 endpoints with full parameters/responses
• Real use cases with actual code
• Error handling patterns
• SLA commitments
• Support channels

4. JSDoc API Documentation

Before: Minimal inline comments
After: Complete apidoc-compatible documentation

Now documents:

• Request parameters (path, query, body)
• Response structure (success and error)
• HTTP headers (RateLimit-*, Retry-After)
• All status codes (200, 202, 401, 404, 409, 429)
• Example cURL commands

🚀 Usage Examples Included

Rate Limiting Examples

# Within limit (19 remaining)
curl -X POST .../api/v1/jobs/12345/export \
  -H "X-API-Key: ak_test_..." \
  -d '{"format":"csv"}'
# Response: 202 Accepted, RateLimit-Remaining: 19

# Rate limit exceeded (0 remaining)
curl -X POST .../api/v1/jobs/12346/export \
  -H "X-API-Key: ak_test_..." \
  -d '{"format":"csv"}'
# Response: 429 Too Many Requests, Retry-After: 1800

Deduplication Examples

# Request 1 (14:00) — trigger export
curl -X POST .../api/v1/jobs/12345/export \
  -H "X-API-Key: ak_test_..." \
  -d '{"format":"csv"}'
# Response: 202 Accepted, exportId: 66f4a8c1

# Request 2 (14:05, same params) — REUSED
curl -X POST .../api/v1/jobs/12345/export \
  -H "X-API-Key: ak_test_..." \
  -d '{"format":"csv"}'
# Response: 200 OK, exportId: 66f4a8c1, "reused": true
# RateLimit-Remaining: 19 (NOT consumed!)

Use Case Examples

Power BI Incremental Refresh (JavaScript):

async function pollExport(exportId, apiKey) {
  let status = 'pending';
  while (status !== 'ready') {
    const res = await fetch(`.../exports/${exportId}`, {
      headers: { 'X-API-Key': apiKey }
    });
    ({ status } = await res.json());
    if (status !== 'ready') await new Promise(r => setTimeout(r, 5000));
  }
  return res;
}

for job_id in 12345 12346 12347; do
  export_id=$(curl -s -X POST ".../jobs/${job_id}/export" \
    -H "X-API-Key: ${API_KEY}" \
    -d '{"format":"csv"}' | jq -r '.exportId')
  
  # Poll until ready...
  
  curl -X GET ".../exports/${export_id}/download" \
    -H "X-API-Key: ${API_KEY}" \
    | aws s3 cp - "s3://bucket/job${job_id}.csv"
