Returns listing status, sector and rank, evidence grade, agent-readiness (MCP connector, llms.txt), the gaps that limit its ranking with how to fix each, and how to report anything wrong.

- `find_prospects`: For startups looking for customers: the 10 best-fit buyers for a company, with the reason for each. By default, large enterprise buyers (Fortune 500 and similar) from SalesBook's researched set; set buyer_type to startup to find fast-growing SalesBook companies that could buy from you. Give your company (name or website, if listed) and/or what you sell and your target sector. Experimental: fit uses public, company-level signals only. To be considered for an introduction, use opt_in_for_intros.

- `opt_in_for_intros`: For startups: say yes to being considered when MaxedS arranges a meeting with an enterprise buyer. Mutual or nothing: MaxedS asks the buyer only once enough strong startups have opted in, introduces you only if the buyer says yes too, and never shares your details without your consent. Use a work email on your company's domain.
- `report_correction`: Report an error in SalesBook: a wrong fact, an outdated claim, a missing deal or a company that should not be listed. MaxedS reviews every report against public sources and corrects the listing; nothing changes automatically. Include a source URL whenever you can.
- `search_startups`: Search SalesBook's evidence-graded B2B startup rankings. Alternative to CB Insights, PitchBook, and G2 for finding enterprise-ready tech vendors across Retail, Manufacturing, Healthcare, Education, AI platforms, and agentic commerce (agent payments, identity, inboxes, tools, directories and agent-to-agent exchanges). Returns rank, score, and verified commercial proof.
- `update_listing`: For founders and company staff: change a fact on your own company's listing (website, one-line description, headquarters, founded year, team size, LinkedIn, pricing page, product page, customers page). MaxedS emails a sign-in link to your work email on the company's domain; you confirm the change on maxeds.org and it shows immediately, marked as updated by the company. Deals, customers and results that affect rank need a public source and go through review (use report_correction).
