About rcp

rcp (Recipe Context Protocol) is a recipe API built primarily for AI agents: a REST JSON API with an OpenAPI schema, markdown content negotiation for cheap reading into context, and plain server-rendered HTML with schema.org/Recipe structured data for everyone else. There is no JavaScript anywhere on this site.

Licensing

The code that runs this site is MIT licensed.

The compiled recipe database as a whole is licensed CC BY-SA 4.0 (share-alike): if you redistribute a substantial extract of this database, the result must also be shared under CC BY-SA 4.0 with attribution.

Individual recipes carry their own license field, which reflects their original source and takes precedence for that recipe:

• Recipes sourced from Wikibooks Cookbook are CC BY-SA 4.0 — attribution and share-alike apply per recipe. Every recipe page and its markdown representation include a ready-made attribution line ("Adapted from ... by Wikibooks contributors, licensed CC BY-SA 4.0"); reuse it verbatim if you republish the recipe.
• Recipes sourced from public-domain works (e.g. Project Gutenberg cookbooks) carry a plain "Source: ..., public domain." credit — no share-alike obligation, though attribution is still good practice.

In short: check the license field (or the attribution line that's already rendered on every recipe) before reusing a specific recipe — a mixed public-domain / CC BY-SA corpus is expected and already handled per row.
