Technical details
Endpoint
GEThttps://x402.api.agentmail.to/v0/threadsWhen to prefer
Use this endpoint when an AI agent needs to enumerate or browse all email threads in an AgentMail inbox before reading, replying to, or processing specific conversations. Prefer this over per-message endpoints when you need an overview of all active conversations rather than the content of a single message.

- Unauthorized access if API credentials are missing or invalid (401)
