Working in the AI automation space (at APEX Automation Group), we kept hitting a wall: how do you let an autonomous agent actually pay for a service or data from another agent without a human in the middle to sign off on a $50 credit card transaction or a manual API key exchange?
Current API infrastructure is built for B2B/SaaS, not Agent-to-Agent (A2A) economies.
A few technical choices I made:
Why Base/USDC? I needed settlement that costs less than the transaction value. Doing a $0.05 data request on Ethereum L1 is impossible. Base gives us the sub-penny finality needed for micro-tasks.
Zero-Knowledge Proofs: We use Schnorr/Curve25519 so agents can prove they have the authority to spend from a treasury without exposing the underlying private keys to the inference engine (LLM), which is a huge security risk.
SQLite WAL Mode: Used for the backend to handle high-concurrency local state management before syncing to the chain.
I'm curious to hear from others working on AI orchestration—how are you handling cross-provider agent trust and payments right now? Is everyone just hardcoding API keys, or is there a move toward decentralized identity?
