AI-powered book search and recommendation chatbot, pay-per-query via x402.
What it does
BookBot is a web application that lets users search for and discover books from a large collection using AI chat. The x402-enabled endpoint at /api/x402 accepts POST requests and returns an HTTP 402 challenge, indicating it is live and requires payment to access. The landing page shows support for multiple GPT model tiers (GPT 4o, GPT 5, GPT 5 Mini) and highlights popular titles like "The Name of the Wind," "The Way of Kings," and "The Alchemist."
Documentation is effectively absent — the /docs, /pricing, /api, and /README paths all return 404. The x402 challenge body was empty (no price, network, or token information was captured), so exact pricing and payment details cannot be confirmed. The robots.txt explicitly disallows crawling of /api/ paths. Without an OpenAPI spec, request/response schemas, or pricing metadata, the endpoint's exact capabilities and cost structure remain unclear.
Given the sparse information, this listing is largely inferred from the landing page content and the live 402 probe. Users should expect a book-search or book-recommendation AI chat endpoint, but should verify pricing and request format directly with the provider before integrating.
