When should an agent pay per call for research vs just use free web search?

I’m trying to figure out what actually belongs behind a paywall for agents. Free search is already good enough for “what is this company?” A lot of the time. But agents still hallucinate contacts, mix up two companies with the same name, and treat a random blog as proof. I built two small tools while testing that problem: Company research that returns a structured summary, domain, and next actions A claim check that takes a sentence and returns supported / not supported plus a source Both are pay-per-call so an agent doesn’t need an API key. What I don’t know: Would you have an agent pay $0.75 for structured company context, or only pay for verified contacts? For claim checks, is a fast $0.10 “supported / not supported” useful, or do agents only want the expensive deep pass? What fields do you actually need in the JSON? I’m trying not to return slop. If this kind of tool is useful, tell me what the response should look like. I can put the endpoints in a comment.
