API overview and the invite model
The API creates an invite. It takes name, email, location, position, pay band, and the offer flag, not an SSN.
API keys and test mode
Test keys start with phb_test_ and finish an invite from a fixture. They do not call Stripe or the screening service.
Webhook events
Verify webhook signatures with the timestamp and body, reject timestamps older than five minutes, and expect retries.
Connect Claude over MCP
Approve an assistant for your organization. It can order an invite and explain steps. It cannot recommend a hire.
Ask Peter
Peter answers check questions and, for a signed-in employer, drafts an invite. A send, resend, or cancel waits for a confirm click.
