  "raw_analysis": "SelectPdf HTML To PDF API is a hosted REST service that converts HTML strings or live web pages into PDF documents. It is a mature, commercially-focused offering from SelectPdf, a vendor known primarily for its .NET PDF libraries. The service targets application developers who need to generate PDFs from web content without managing headless browsers or rendering infrastructure. Integration is straightforward, requiring only an API key obtained from a SelectPdf account. Because the API is hosted and key-authenticated, it is a standard REST platform integration rather than a tool without a public API. Pricing follows a subscription/credit model with a trial, and specific rate limits are plan-dependent rather than publicly documented. Key capabilities include HTML-to-PDF and URL-to-PDF conversion, along with document customization options such as headers, footers, and margins. It competes with services like DocRaptor, PDFShift, and Puppeteer-based self-hosted solutions. For integration purposes, developers should expect an API key auth flow and endpoint-specific payloads, and should confirm current pricing and rate limits directly with the vendor."

    "Publish a machine-readable pricing.json and include tier details directly in llms.txt so agents can quote exact costs without scraping.",
    "Add an 'agent quickstart' section to llms.txt covering API key creation, auth header format, and a minimal curl example.",
    "Expose a status.json or uptime endpoint so agents can programmatically assess reliability.",
    "Clarify platform support matrix (Windows-only .NET library vs. cross-platform REST) prominently in llms.txt to prevent wrong-recommendation paths."
