Apoa
APOA stands for Agentic Power of Attorney, an open authorization standard designed specifically for securing interactions between AI agents and services. It establishes a trusted infrastructure where human principals or delegators can sign cryptographic grants that define exactly what an AI agent is permitted to do. Each grant specifies the granting principal, the receiving agent, the target service, the allowed actions or scopes, and specific constraints such as time expiration and revocation capabilities. The system is built to answer critical security questions including the source of authority, the scope of permissions, and whether a proposed action falls within the granted limits. APOA supports delegation chains, allowing authority to be passed down with shrinking permissions, ensuring a secure and auditable trail of trust. The platform provides official SDKs for both TypeScript and Python, enabling developers to easily generate key pairs, create signed tokens, validate credentials, and check authorizati
