Study web-search-enabled-api-answers-v1 sent the 13 exact prompts below to two fixed models through the official Anthropic Messages API with web search available: 26 total cells. It replaces an exploratory consumer-interface panel that is not cleared for publication. No result from that earlier panel entered this report.
Scope is US, English, Anthropic Messages API. Every cell used one frozen response state: answered, refused, empty, truncated, provider_error, ambiguous_transport, unavailable. Search and citation observations stay separate. Brand controls remain separate from nonbrand discovery, and the report combines both model configurations into panel-wide raw counts only—never model-level result rows, provider rankings, overall scores, or statistical claims.
The US setting applies only to the approximate location sent to web search. Model inference uses Anthropic's global routing. This study measures two model configurations inside one API, not providers or consumer products.
These API outputs are not the consumer Claude.ai experience or Anthropic's views. They are a bounded test of two web-enabled developer models under the commercial terms reviewed on 2026-08-07. The study does not publish raw answers, private receipts, session material, or a claim that its selected prompts represent AI money advice generally.
Third-party names identify only the measured API and models. Foundable is not affiliated with, sponsored by, endorsed by, or approved by Anthropic, and Anthropic has not reviewed this protocol. Read the commercial terms effective June 17, 2025.
The collector uses a $200 local request-start and accounting budget. Its conservative planning reservation is $185.98736; expected provider spend is below $5. This local guard is not an absolute invoice cap. Only a dedicated provider-side spend limit can provide that backstop.
A retained run reports response states for all 26 cells. Answer-quality criteria use only answered nonbrand cells, up to 22. Foundable visibility uses all 22 nonbrand cells alongside the answered-nonbrand count. Brand resolution uses all 4 controls alongside the answered-control count. Search is used, not used, or unobservable across all 26 cells. Citation presence uses answered cells with separate nonbrand and control denominators; every citation-claim attachment is supported, contradicted, or unverified. An uncited answer is not applicable for support.
Present only when the case-insensitive word Foundable appears in answer text for a nonbrand cell; citations and URLs do not count. Resolved only when the answer identifies Foundable as the business-building product at foundable.com without assigning its name or capabilities to another entity. Resolved when a brand-control answer identifies Foundable correctly and directly addresses the Foundable capability named by that prompt; otherwise record misresolved or unresolved.
