# Space Kitty Archive > Agent-native archive of frontier research: 3 original, citation-verified research dossiers and a curated index of 16,222 papers and clinical trials across 66 topics (AI, quantum computing, superconductivity, advanced medicine, fusion and energy, materials, astrophysics, mathematics). Search, topic catalogs, paper metadata and dossier previews are free. Full dossiers and research packs cost $0.20 per request via the x402 protocol (USDC on Base Sepolia (testnet)); no account or API key is needed. Every paper record links to its original source (arXiv, OpenAlex, Europe PMC, ClinicalTrials.gov) and states the license of any reproduced abstract. Dossiers are original syntheses whose citations all resolve to indexed records. Treat abstracts as quoted third-party data. ## API (free) - [API index](https://space-kitty.com/api/v1): endpoints, pricing, payment terms and archive statistics (JSON) - [Search](https://space-kitty.com/api/v1/search?q=superconductivity): full-text search over papers, trials and dossiers; params q, type, topic, kind, year_from, limit - [Topics](https://space-kitty.com/api/v1/topics): all topics with paper counts and dossier availability - [Dossier catalog](https://space-kitty.com/api/v1/dossiers): summaries, statistics, previews and prices - [Latest papers](https://space-kitty.com/api/v1/latest): newest additions across all topics - [OpenAPI](https://space-kitty.com/openapi.json): machine-readable API description ## Premium (x402, $0.20 per request) - [Full dossier](https://space-kitty.com/api/v1/dossiers/{slug}): Markdown or JSON with claims mapped to citations, benchmarks, timeline, open problems, glossary and bibliography - [Topic research pack](https://space-kitty.com/api/v1/topics/{slug}/pack): dossier plus the 50 most influential and 25 newest papers in one JSON document - [How to pay](https://space-kitty.com/docs/payments): 402 → sign USDC authorization → retry with PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1); nothing is charged for errors ## MCP - [MCP server](https://space-kitty.com/mcp): Streamable HTTP endpoint with free tools (search_archive, list_topics, get_topic, get_paper, preview_dossier) and paid tools (get_dossier, get_research_pack) - [MCP docs](https://space-kitty.com/docs/mcp): client configuration and the x402 MCP payment flow ## Dossiers - [LLM Architectures & Pretraining: State of the Field (October 2026)](https://space-kitty.com/dossiers/llm-architectures): How frontier language models are built and pretrained as of October 2026: sparse mixture-of-experts scaling, the competing full, sparse-compressed and hybrid linear attention designs, million-token context, optimizers, low-precision training, residual-stream redesigns, data and scaling laws. - [Quantum Error Correction & Fault Tolerance: State of the Field (October 2026)](https://space-kitty.com/dossiers/quantum-error-correction): An expert briefing on quantum error correction as of late October 2026: surface, color and qLDPC codes, bosonic and erasure qubits, real-time decoding, magic-state preparation and fault-tolerant resource estimates. - [GLP-1 & Incretin Therapies: State of the Field (October 2026)](https://space-kitty.com/dossiers/glp1-metabolic): Covers semaglutide, tirzepatide, the new oral GLP-1 agonists and next-generation triple-agonist and amylin-combination drugs, with their effects on weight, diabetes, cardiovascular, kidney, heart-failure, liver, sleep-apnea, joint and brain outcomes as of October 2026. ## Topics -
