Tools
| Tool | Description | Behaviour |
|---|---|---|
| buy_decision_evidence | Starts a Stripe checkout for the full evidence behind one decision: sourced and dated figures, what would flip the answer, and the brief's stated limits. Returns a checkout URL for the user to approve and pay, and a session_id. After the user pays, call get_decision_evidence with both ids. Always show the price and get the user's go-ahead before sending them to pay. | Changes data |
| get_decision_brief | Everything public about one brief: the six decisions it covers with the evidence line for each, pages, edition, price, sample pages, free answers, guarantee, license and payment link. The PDF itself is delivered only after payment. | Read-only |
| get_decision_evidence | Returns the full evidence for one decision once it is paid for. Pass the session_id from buy_decision_evidence, or the Checkout Session id of a full brief, team license, pack or all-access purchase that includes this decision. | Read-only |
| get_document | Every published finding (question and answer) of one CULT+MATH study or answer page, with its date, license, citation line and related brief. | Read-only |
| list_decision_briefs | List the CULT+MATH Decision Briefs: who each is written for, its headline finding, price, page and payment link. Also lists bundles and the custom brief. | Read-only |
| list_decisions | The 54 decisions inside the briefs (six per brief), each with who owns it, who contests it, and the public evidence line. Use an id with buy_decision_evidence to buy the full evidence for just that decision. | Read-only |
| run_ai_visibility | Use when the user asks whether their brand or website shows up in AI answers, or who AI assistants cite instead. Asks ChatGPT, Claude, Gemini and Perplexity the buyer's question live with web search on, three times each on the everyday model and once on the flagship model, and returns per platform: in how many askings the domain was cited and at what positions, whether that held every time, and whether the flagship model agrees. Also how many platforms cite it and the domains cited most instead (not the answers themselves). A platform that cites nothing is reported as not measured. Safe to cite: its controls are checked first, it states its limits, and every result carries a run id, a date and a citation line. If a control fails it refuses and you are not charged. This tool charges nothing: it validates the request and returns a payment_url, the price and instructions. Pay by POSTing to payment_url over MPP (HTTP 402, a Stripe shared payment token from your wallet). Price: $5.00 per run, charged only when the run comes back sound; pay over MPP (a Stripe shared payment token) or x402 (USDC on Base, no account needed). A real sample of this run, free: https://cultmath.com/agent/samples/ai-visibility.json | Read-only |
| run_angle_demand | Use when the user is choosing a positioning, a message or a campaign angle and asks which benefit or reason to buy matters most to buyers, or which is gaining. Returns, for each angle searched with the category, its share of searches among the angles named, its year-on-year change and its growth beyond an everyday control basket, with a volume band. Shares and bands only. Safe to cite: its controls are checked first, it states its limits, and every result carries a run id, a date and a citation line. If a control fails it refuses and you are not charged. This tool charges nothing: it validates the request and returns a payment_url, the price and instructions. Pay by POSTing to payment_url over MPP (HTTP 402, a Stripe shared payment token from your wallet). Price: $3.00 per run, charged only when the run comes back sound; pay over MPP (a Stripe shared payment token) or x402 (USDC on Base, no account needed).

| run_answer_share | Use when the user asks which brands or websites AI assistants rely on for their category, who they are competing with in AI answers, or whether any source dominates. Asks ChatGPT, Claude, Gemini and Perplexity 2-3 buyer questions live, each twice, and returns the most-cited domains as counts of answers, whether the category is owned, led, contested or fragmented, whether the leaders hold from one asking to the next, and, if given, where your domain stands. Not the answers themselves. Safe to cite: its controls are checked first, it states its limits, and every result carries a run id, a date and a citation line. If a control fails it refuses and you are not charged. This tool charges nothing: it validates the request and returns a payment_url, the price and instructions.

| run_channel_mix | Use when the user is planning go-to-market or channel strategy and asks where buyers look, whether to prioritise retail, review sites, their own site or communities, or who controls the first page for their category. Searches Google live for 1-3 buyer queries and classes every top-10 organic result by domain: retailers and marketplaces, reviews and media, brand sites, forums and social, reference, independent and specialist sites. Returns the share each class holds, who leads each class, and who takes the top three places. Domains and counts only. Safe to cite: its controls are checked first, it states its limits, and every result carries a run id, a date and a citation line. If a control fails it refuses and you are not charged.

| run_claim_check | Use when the user is choosing a positioning, a tagline or a message and asks whether competitors already say it, whether a claim is crowded or open, or who has moved onto it recently. Reads each competitor's home page today and its Internet Archive copy from a year ago, and returns, per site, whether it leads with the claim, mentions it, or does not, and whether that changed this year, with a verdict: open, mentioned but not owned, taken, or crowded.

Returns, quarter by quarter, the 8-K merger-agreement documents that mention the sector as a share of all 8-K merger agreements, from SEC EDGAR full-text search, whether that share is rising or falling, an industry-code cross-check, and the most active filers with their latest filing linked.

| run_demand_check | Use when the user asks whether interest in a product, category or trend is really growing, or wants to know if a rise in search is more than noise before investing in it.

| run_disclosure_check | Use when the user asks whether any company, or which of a named set of competitors, now reports a figure (a franchise share, ARPU, a retention rate, a concentration, a multiple), or whether a public comparable discloses the metric a deal model depends on. Returns, from SEC EDGAR full-text search, which filers use the phrase in their filings over the years given, with the first and latest filing linked; for named peers, who does, who does not, and who could not be measured because they filed nothing.
