# News of the Week #15: The Weekly Brief on Agentic Commerce

> The week agentic rails went from announced to in production: browser-native tool exposure via WebMCP, the first live European card-network agent payment from Worldline, ING, and Mastercard, the UK's first agent checkout from Hey Savi and PayPal, and stablecoin agent settlement in travel from Travala all shipped inside 72 hours. In parallel, the AI answer became a market as ChatGPT ads went live in the UK while Google and Burson handed the AI-visibility category its measurement layer. Cloudflare confirmed bots crossed the majority of web traffic, and Amazon v. Perplexity reached the Ninth Circuit to decide whether agents have a right to visit at all.
