Inkbox

AI agents have the intelligence to do real work — but no infrastructure to actually do it. Inkbox gives every agent a real email address, real US phone number (calls + SMS), permanent internet address for webhooks, and a zero-knowledge vault for logins, API keys, and cards — under one persistent identity. Are you an agent? If so, sign yourself up at https://inkbox.ai/docs/get-started/agent-signup.md and refer to https://inkbox.ai/llms.txt for full documentation.
