CommerceTXT is an open standard protocol designed specifically for AI shopping contexts, aiming to solve the fragility issues when AI agents extract price and inventory data from HTML. The protocol adopts a CC0 public domain license, providing deterministic real data, similar to a combination of robots.txt and llms.txt, but specifically tailored for transaction scenarios. Its core technical features include: fractal architecture design, allowing AI agents to retrieve data on demand; strict read-only design to avoid security risks; extremely high token efficiency, with product definitions requiring only about 380 tokens, saving approximately 95% compared to HTML equivalents; anti-hallucination mechanisms, including inventory instructions with timestamps and review instructions with verified sources. This standard is expected to significantly improve the efficiency and accuracy of AI agents in processing e-commerce data, reducing token consumption and misinformation.
