Coastline Index’s Machine-Readable GTA 6 Data: llms.txt and JSON APIs Coastline Index, a GTA VI reference layer, has launched with machine-readable data for LLMs and tools, featuring Rockstar-confirmed information only, structured entities, and hooks like XML sitemaps, llms.txt, and JSON APIs. The project aims to provide a vetted corpus for developers to ground chatbots and tools, reducing reliance on speculative content. We built Coastline Index as a GTA VI reference layer that LLMs and tools could safely consume, not just another fan site. Core ideas • Rockstar-confirmed only: if it’s not from an official Rockstar source, it doesn’t go into the dataset. • Structured entities: release, platforms, editions, characters, Leonida region, official videos. • Machine hooks: XML sitemap, llms.txt, and JSON APIs for entities + current status. What llms.txt does for us • Points crawlers explicitly at high-signal pages and APIs • Documents our scope: GTA VI only, verified information, multilingual front-end • Reduces the chance that models learn from outdated or speculative content instead of our curated set For devs this means you can: • Hit an API instead of parsing HTML or scraping rumor threads • Ground chatbots and tools in a small, vetted corpus • Rely on a public data update log that shows when facts changed and why If you’re experimenting with game-aware AI or just want a clean GTA 6 data source, this is what we’ve shipped so far: https://coastlineindex.com https://coastlineindex.com
