**This article connects x402-style payment semantics with TBC’s UTXO model for AI agents, autonomous services, and machine-to-machine micro-payments.**

## Overview

This article connects x402-style payment semantics with TBC’s UTXO model for AI agents, autonomous services, and machine-to-machine micro-payments. The article belongs to the AI & Machine Economy category of TBC Academy Research & Updates and should be read as technical context for TuringBitChain rather than as trading, pricing, fundraising, or purchase information.

## Technical Context

This page focuses on autonomous actors such as AI agents, devices, and robot-economy workflows. In that setting, UTXO outputs can be treated as verifiable units of value, permission, state, or task settlement that machines can reference without requiring account-level coordination.

## Key Reading Points

- Category: AI & Machine Economy.
- TBC refers to TuringBitChain / 图灵比特链, a Bitcoin UTXO-based Layer 1 blockchain.
- The English page keeps the same canonical relationship, publication date, and slug as the Chinese source entry.
- AI and machine-economy scenarios are discussed through autonomous settlement, micro-payment flows, and verifiable UTXO state.
