Setup (API key)

Before doing anything else — check if the API key is already configured:

python3 skills/trendproof/scripts/trendproof.py configure --show

If no key is found, stop and tell the user exactly this (do not attempt any API calls):

"To use TrendProof, you need a free API key.

1. Open https://trendproof.dev/dashboard#keys (sign up if needed — 5 free trial credits included)
2. Copy your key (starts with TRND_) and send it to me"

Once the user provides the key, save it:

python3 skills/trendproof/scripts/trendproof.py configure --api-key TRND_xxxxx

Or set the environment variable:

export TRENDPROOF_API_KEY=TRND_xxxxx

Troubleshooting

• No key configured: Run configure --show. If empty → ask user to get key at https://trendproof.dev/dashboard#keys
• 401 / unauthorized: Key is set but invalid or revoked. Ask user to rotate at trendproof.dev/dashboard → API Keys → Rotate.
• 429 / credits exhausted: Upgrade at trendproof.dev/dashboard → Billing.
• Slow response (>5s): DataForSEO live API — expected for uncached keywords.
• score = 0 + stable: Likely very low-volume keyword; check trend_data array.
