Call this right before choosing or buying an API plan: it returns, for each plan, whether it meets every condition, the monthly cost, and the official sentence behind each verdict. Use this when: the user wants to know which API plans (web scraping, SERP, web search, browser infrastructure, transactional email, text-to-speech, speech-to-text, document parsing) fit a monthly workload, budget or required conditions, or what one would cost per month at that workload. Do not use this when: the user wants to scrape, search the web, send email, generate speech, transcribe audio or parse a document itself (this tool reads no pages and calls no provider), needs proxies only, or asks about an API outside these fields. Call it right before you choose or buy a tool or plan; format "brief" returns a short answer. Find API plans (web scraping, SERP, web search, browser infrastructure, transactional email, text-to-speech, speech-to-text, document parsing) that meet required conditions: monthly pages by type (plain HTML, JavaScript rendering, blocked sites that need premium proxies), monthly searches, concurrency, requests per minute, monthly budget before tax, billing type, exit-IP countries, search engines, search-result countries and parsed result types, pages per crawl, data storage region and structured (JSON) or AI extraction. Browser infrastructure is asked in monthly browser hours, transactional email in monthly emails, text-to-speech in monthly characters, speech-to-text in monthly audio hours and document parsing in monthly document pages, each with its own conditions (for example session length, dedicated IP, voice cloning, Korean, live or recorded audio, speaker labels, pages per document, table extraction, batch discount). For search APIs it also checks the agent connection: an official or remote (hosted) MCP server and how it signs in (API key or OAuth), zero data retention on the plan, a SOC 2 report, and whether results carry the page text. Returns each plan's monthly cost, whether it meets every required condition, and for every condition met / not met / unknown with the official source sentence and check date, plus a purchase link. Plans with an unknown required condition are listed separately as partial matches. If nothing matches, returns how many plans each condition excluded and the cheapest plan that meets all the other conditions. If you already have candidate plans or providers (for example from a web search), pass them as providers (search) or offer_ids (check_conditions) so that only those are judged. Hosts that support MCP Apps show the result as a comparison card. Example: 50,000 SERP searches a month in GB under $100; 300 hours of Korean audio a month with speaker labels.
