    search_docsSemantic search over the complete MarketCheck API documentation, current rate plans, and API policies (2,000+ indexed sections). Returns the most relevant excerpts, each with its source page URL and endpoint. Use this first for any question about endpoints, parameters, authentication, errors, plans, or terms.
    get_doc_pageFetch one full documentation page as Markdown, including resolved parameter tables and curl examples. Use a 'Page:' URL or path returned by search_docs or get_endpoint, e.g. '/docs/api/cars/inventory/inventory-search'. UK pages are under '/uk/docs/...'.
    list_endpointsList every documented MarketCheck REST endpoint: method, path, one-line title, region, and docs URL (~73 endpoints across US/UK cars, dealers, VIN decode, history, valuations).
    get_endpointExact reference for one REST endpoint: every query parameter (name, type, description, required, default), a real sample request, and a truncated real sample response. Use the path as shown by list_endpoints, e.g. '/v2/search/car/active'.
    get_plans_and_limitsCurrent published MarketCheck rate plans: per-call pricing, monthly quotas, and rate limits for a region, sourced from the live plan list (authoritative over docs). NA prices in USD, UK in GBP.
