Connection key
Sign in with an email link. Your first confirmed sign-in creates your account and key automatically in Account.

Basic: by default 100 checks per day and 1,000 per month, without screenshots. Account and me_get show exact limits and usage. Request the free 500/5,000 package in Account; it starts after approval.
New keys can be shown and copied again after sign-in. Older keys still work but cannot be recovered: create a replacement, update your integration, then revoke the old key. Keep your key private.
First test
Check the key with GET /api/v1/me. Create a test with POST /api/v1/tests, send your email through your own service to all send_to addresses and open results_url. Creating a test does not send the message.
Transport and limits
The Agent Card is discovery. Use the REST bindings listed in capabilities.skills; a separate A2A JSON-RPC task transport is not available. For tool calling use remote MCP.
All protocols share the same key quota. Reading a result does not spend a check. Request history and free package requests are in Account.
