Quick Start

1. Get an API key

$ curl -X POST https://whatsapp-backend-knd2.onrender.com/v1/keys \
>   -H "Content-Type: application/json" \
>   -d '{"email": "you@company.com"}'

1 {
2   "api_key": "cs_live_abc123...",
3   "tier": "free",
4   "monthly_limit": 100,
5   "message": "Store this key securely — it won't be shown again."
6 }

Save your key. It’s only shown once.

2. Search case studies

$ curl -X POST https://whatsapp-backend-knd2.onrender.com/v1/casestudies/semantic \
>   -H "X-API-Key: YOUR_KEY" \
>   -H "Content-Type: application/json" \
>   -d '{"query": "companies that reduced churn with better onboarding", "limit": 5}'

Or use filtered search for exact lookups:

$ curl https://whatsapp-backend-knd2.onrender.com/v1/casestudies?company=checkout&industry=ecommerce \
>   -H "X-API-Key: YOUR_KEY"
