Verified Agent Identity

This is a decentralized identity system for AI agents built on the Billions Network and iden3 protocol. It lets you create Ethereum-based DIDs, link them to human owners via ERC-8004 attestations, and generate cryptographic proofs for authentication. The main use cases are Know Your Agent workflows and handling HTTP 402 Payment Required responses by signing payment headers. Everything lives in a local directory with your private keys, which can be encrypted with a master key or stored in plaintext. The guardrails are strict: you have to check for existing identities before running most scripts, and you're explicitly forbidden from manual crypto operations or file manipulation if something breaks. It's a serious identity tool with training wheels bolted on.
