Recursion ========= An important exception to [sandboxing](../inscriptions.md#sandboxing) is recursion: access to `ord`'s `/content` endpoint is permitted, allowing inscriptions to access the content of other inscriptions by requesting `/content/<INSCRIPTION_ID>`. This has a number of interesting use-cases: - Remixing the content of existing inscriptions. - Publishing snippets of code, images, audio, or stylesheets as shared public resources. - Generative art collections where an algorithm is inscribed as JavaScript, and instantiated from multiple inscriptions with unique seeds. - Generative profile picture collections where accessories and attributes are inscribed as individual images, or in a shared texture atlas, and then combined, collage-style, in unique combinations in multiple inscriptions. The recursive endpoints are: - `/r/blockhash/<HEIGHT>`: block hash at given block height. - `/r/blockhash`: latest block hash. - `/r/blockheight`: latest block height. - `/r/blocktime`: UNIX time stamp of latest block.
