Build Something Agents Want developer resources
This page is the named developer-resources hub for the product. Use it when you need machine contracts for the Twin Score catalog: slugs, scores, capability matrices, SKILL.md, OpenAPI, and a CC BY 4.0 dataset. Do not use it when you need a human comparison essay — that is the people twin.
When to use
- GET /api/v1/products and /api/v1/products/{slug}
- GET /api/v1/reviews?product={slug}
- OpenAPI at /openapi.json with RFC 9457 errors on misses
- SKILL.md at /skills/{slug} and /.well-known/agent-skills/index.json
- Dataset /dataset/twin-scores.json and .csv (CC BY 4.0)
- llms.txt and llms-full.txt
- Accept: text/markdown on canonical HTML pages
When not to use
No unofficial MCP is advertised. No fake UGC. No Argentina-only geo pages. A 3D canvas, if present, is decoration; the facts on this page are in the HTML. Accept: text/markdown is honored unless Next RSC headers are present.
