AgentCard provides a sandbox environment for development and testing. All API keys use the sk_test_ prefix and all sandbox operations use test payment rails — no real money is charged.

​
Base URL

All API requests in sandbox mode should use: 
https://sandbox.api.agentcard.sh
For example: 
curl https://sandbox.api.agentcard.sh/api/v1/cards \
  -H "Authorization: Bearer sk_test_..."

Getting started

  1. Install the admin CLI and log in
  2. Create an organization and API key
  3. Use https://sandbox.api.agentcard.sh as your base URL for all API calls
The admin CLI defaults to the sandbox environment — no extra configuration needed.
All examples in this documentation use the sandbox base URL (sandbox.api.agentcard.sh). Replace with api.agentcard.sh when you’re ready to go live.
