Agents on the open web: browsing inside a decisioning loop

Frequently asked

Questions readers ask about this.

What is agentic browsing?
Agentic browsing is a scoped, auditable capability that lets AI agents fetch, read and cite public web pages as part of a decisioning loop, with every fetch stored as a first-class object with URL, timestamp and content hash.
Why let agents browse the open web at all?
Because hypothesis authorship is the only station in a revenue decisioning loop that is not naturally bounded by first-party data. External context is what lifts hypotheses out of the operator's own data distribution and the model's pre-training.
How is prompt injection handled when agents browse public pages?
Fetched content is never composed directly into a system prompt. It is parsed to strip instructions, preserved as evidence in a separate context slot, and the agent is prompted to reason over it as data. A red team injection suite runs weekly against a rotating pool of real fetched pages.
Can Markin agents purchase, sign up or submit forms on third-party sites?
No. The browsing layer is read-only against any surface the operator does not own. Any write goes through the workspace action layer with human authorization.
