Step 1
Get your sandbox key
Each visitor gets an ephemeral 24-hour key — already minted.

Step 2
Identify your sandbox
Confirm the key works by hitting /me.
curl https://api.everycent.ai/v1/me \ -H "Authorization: Bearer ec_sandbox_••••xyVE"

List demo customers
The sandbox is pre-seeded with 20 customers.

Step 4
Create an invoice

POST /v1/invoices
Step 5
Send the invoice
