Dr. T

A developer built Dr. T, an autonomous clinical intelligence platform that combines FHIR-based longitudinal EHR summarization, computer-vision dermoscopy analysis, and multimodal reasoning with verified PubMed citations. The system also includes the Trib-House Living Library Commons for preserving indigenous botanical knowledge and an x402 micro-transaction engine on Algorand MainNet that lets autonomous agents pay per request for medical AI APIs in USDC. The developer said machine-readable discovery via /.well-known/x402.json proved as vital as search engines were for the web.

Dr. T What does it do: Dr. T is an autonomous clinical intelligence, multilingual healthcare companion, and decentralized AI ecosystem. It bridges human-centric patient care, advanced clinical informatics, and machine-to-machine AI economies. Here is what Dr. T does across its core pillars: Personalized Health Soulmate: Adapts tone, cultural context, and medical communication styles to patients, caregivers, and clinicians. FHIR Longitudinal Summarizer: Ingests multi-hospital Electronic Health Record EHR bundles and compresses complex patient histories into prioritized clinical risk alerts. SmArtist Spectroscopic Dermoscopy AR : Performs multi-dimensional computer-vision analysis on skin lesions to estimate malignancy risks and guide clinical next steps. Parallel Search & Multimodal Synthesis: Combines Gemini multimodal reasoning with verified PubMed/clinical citations to generate broadcast-ready health media. Trib-House Living Library Commons Ethnobotanical & Biodiversity Preservation: An open, sovereign knowledge repository preserving indigenous botanical medicine and biodiversity wisdom from 16+ countries with cryptographic provenance. x402 Sovereign Micro-Transaction Engine Algorand MainNet Pay-Per-Request AI Services: Protects high-value medical APIs and AI models behind HTTP 402 paywalls, allowing autonomous agents and researchers to query endpoints on-demand without monthly SaaS subscriptions. Instant L1 Settlement: Settles microtransactions in USDC on Algorand MainNet 2.7s finality, <$0.001 fee via the GoPlausible facilitator and indexed on the Bazaar Discovery Catalog. Inspiration: Health issues in 2026 have given experiences of blessings of a real life figure with heart and mind - Dr. T. Her legacy would go towards infinity. What I have learned along the way: Dr. T is social based with humans as center, building it from a clinical companion into a decentralized, full-stack intelligence platform yielded several fundamental lessons across healthcare, distributed systems, and the emerging agentic economy: HTTP 402 as the Native Protocol: Reviving the native HTTP 402 status code combined with microtransactions turns any API into a trustless vending machine. An agent pays fractions of a cent 0.02 USDC , receives the computed output instantly, and moves on without ongoing financial liability. Machine Discovery is Key: Having a paywall is useless if agents cannot find it. Implementing self-describing schemas via /.well-known/x402.json and catalogs like GoPlausible Bazaar showed that machine-readable discovery is as vital as search engines were for the web. Empathy Without Evidence is Dangerous: Conversely, a compassionate bedside manner is meaningless without strict grounding in verified standards such as CPIC pharmacogenomic rules, FHIR data structures, and PubMed literature . Evidence-to-Screen Impact: Automating the conversion of clinical findings into short, cinematic 2D/3D explainers Dr. T Cinema dramatically boosts patient retention and compliance compared to traditional pamphlets or portal text. Privacy Cannot Be an Afterthought in Health Tech Local-First & Zero-Knowledge: Sensitive health data—especially genomic markers and biometric scans—should never be centralized unnecessarily. Employing local processing, differential privacy, and zero-knowledge proofs demonstrated that diagnostic utility does not require compromising patient sovereignty. Preserving Traditional Wisdom Ethically Bridging Ancient Knowledge and Modern Science: Developing the Trib-House Commons revealed that indigenous botanical knowledge is disappearing rapidly. Preserving it through cryptographic provenance ensures cultural attribution, fair benefit-sharing, and ethical study alongside modern pharmacogenomics. https://youtu.be/JnH1HZPd9Ds?si=CVz08o2cVmMXCRXi https://youtu.be/JnH1HZPd9Ds?si=CVz08o2cVmMXCRXi Language: TypeScript 5.7 Strict static typing across client & server Build & Bundling: Vite 6 with @vitejs/plugin-react Styling: Tailwind CSS v4 @tailwindcss https://dev.to/tailwindcss /vite with custom responsive themes and typography Iconography: Lucide React Micro-Interactions & FX: canvas-confetti, custom CSS keyframes, and canvas-based spectroscopic visualizers Typography: Google Fonts Plus Jakarta Sans, Playfair Display, JetBrains Mono Production Bundler: esbuild compiling into a standalone CJS server dist/server.cjs Web Framework: Express 5 RESTful endpoints, middleware, static SPA serving Deployment Platform: Google Cloud Platform Cloud Run & Containerized Containers Multimodal Capabilities: Evidence-to-screen scriptwriting and visual storyboarding Dr. T Cinema Multilingual natural language translation and empathetic conversational tone Google Parallel Search & medical literature grounding PubMed / clinical citations Spectroscopic computer vision for lesion classification SmArtist Settlement Asset: USDC ASA Asset ID: 31566704 with sub-3s deterministic finality Payment Protocol: RFC HTTP 402 Payment Required with standard WWW-Authenticate: x402 headers Facilitator Gateway: GoPlausible Facilitator https://facilitator.goplausible.xyz https://facilitator.goplausible.xyz Autonomous Agent Discovery: Bazaar Discovery Specification published via /.well-known/x402.json and /api/x402/bazaar/discovery On-Chain Explorers: Lora Algokit & Pera Explorer integration Authentication & Security: Firebase Auth & local-first zero-knowledge proof primitives CORS & Middleware: Express cors and custom security headers Pharmacogenomics: CPIC Guidelines Clinical Pharmacogenetics Implementation Consortium for gene-drug metabolism inference CYP2D6, CYP2C19 Biodiversity Commons: Cryptographic provenance hashes for ethnobotanical records across 16 countries MediaStream & Canvas API: Camera and video capture for dermatological AR diagnostics and live interaction Web Audio API: Real-time voice and sound processing
