Grammarly Debug Bundle

Overview

Collect Grammarly API connectivity status, text analysis response quality, authentication state, and rate limit usage into a single diagnostic archive. This bundle helps troubleshoot text check failures, missing suggestions, OAuth token expiration, and API response latency.

Debug Collection Script

bash
#!/bin/bash
set -euo pipefail
BUNDLE="debug-grammarly-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BUNDLE"

# Environment check
echo "=== Grammarly Debug Bundle ===" | tee "$BUNDLE/summary.txt"
echo "Generated: $(date -u +%Y-%m-%dT%H:%M:%SZ)" >> "$BUNDLE/summary.txt"
echo "GRAMMARLY_API_KEY: ${GRAMMARLY_API_KEY:+[SET]}" >> "$BUNDLE/summary.txt"
echo "GRAMMARLY_CLIENT_ID: ${GRAMMARLY_CLIENT_ID:+[SET]}" >> "$BUNDLE/summary.txt"

# API connectivity — text check endpoint
HTTP=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer ${GRAMMARLY_API_KEY}" \
  -H "Content-Type: application/json" \
  -X POST https://api.grammarly.com/v1/check \
  -d '{"text": "This are a diagnostic test sentence with intentional grammar errors to verify the API returns suggestions."}' \
  2>/dev/null || echo "000")
echo "API Status: HTTP $HTTP" >> "$BUNDLE/summary.txt"

# Full text check response
curl -s -H "Authorization: Bearer ${GRAMMARLY_API_KEY}" \
  -H "Content-Type: application/json" -X POST https://api.grammarly.com/v1/check \
  -d '{"text": "This are a diagnostic test sentence with intentional grammar errors to verify the API returns suggestions."}' \
  > "$BUNDLE/text-check.json" 2>&1 || true

# Account info and rate limit headers
curl -s -D "$BUNDLE/rate-headers.txt" -H "Authorization: Bearer ${GRAMMARLY_API_KEY}" \
  https://api.grammarly.com/v1/account > "$BUNDLE/account.json" 2>&1 || true

tar -czf "$BUNDLE.tar.gz" "$BUNDLE" && rm -rf "$BUNDLE"
echo "Bundle: $BUNDLE.tar.gz"

Analyzing the Bundle

bash
tar -xzf debug-grammarly-*.tar.gz
cat debug-grammarly-*/summary.txt                 # Auth + API status
jq '.alerts | length' debug-grammarly-*/text-check.json  # Suggestion count
jq '.alerts[] | {type, text}' debug-grammarly-*/text-check.json  # Suggestion details
grep -i "ratelimit\|retry" debug-grammarly-*/rate-headers.txt

Common Issues

| Symptom | Check in Bundle | Fix | |---------|----------------|-----| | API returns 401 | summary.txt shows HTTP 401 | Refresh OAuth token or regenerate API key in Grammarly Developer Hub | | Zero suggestions returned | text-check.json has empty alerts array | Verify text exceeds minimum word count (30 words); check language parameter | | High latency (>5s) | text-check.json shows slow response time | Reduce text payload size; check for network proxy interference | | Rate limited (429) | rate-headers.txt shows Retry-After | Implement request queuing; reduce check frequency per user session | | Client ID mismatch | account.json returns permission error | Verify GRAMMARLY_CLIENT_ID matches the app registered in Developer Hub |

Automated Health Check

typescript
async function checkGrammarly(): Promise<void> {
  const key = process.env.GRAMMARLY_API_KEY;
  if (!key) { console.error("[FAIL] GRAMMARLY_API_KEY not set"); return; }

  const res = await fetch("https://api.grammarly.com/v1/check", {
    method: "POST",
    headers: { Authorization: `Bearer ${key}`, "Content-Type": "application/json" },
    body: JSON.stringify({ text: "This are a test sentence with grammar errors for diagnostic purposes and validation." }),
  });
  console.log(`[${res.ok ? "OK" : "FAIL"}] API: HTTP ${res.status}`);

  if (res.ok) {
    const data = await res.json();
    console.log(`[INFO] Suggestions returned: ${data.alerts?.length ?? 0}`);
  }
}
checkGrammarly();
