Authentication

Get your API key

Request an API key with a single POST request. No signup, no dashboard — the key is sent directly to your email.

curl -X POST https://growthservice.org/api/v1/auth/request-key \
  -H "Content-Type: application/json" \
  -d '{"email": "you@company.com"}'

{ "message": "API key sent to your email." }

Check your inbox for an email containing your API key (format: gsk_...). One key per email address — requesting again sends the same key.

Using your API key

Include your API key in the Authorization header as a Bearer token:

Authorization: Bearer gsk_YOUR_API_KEY

curl https://growthservice.org/api/v1/orders \
  -H "Authorization: Bearer gsk_abc123def456"

Errors

Rate limits

API requests are rate-limited to prevent abuse:

Rate-limited requests return HTTP 429. Retry after the Retry-After header value (in seconds).
