> For AI agents: the documentation index is at https://sdk.nimbusprivacy.xyz/llms.txt, and every page is available as Markdown at its URL with .md appended. # API reference (/reference) This section documents everything `@umbra/nimbus-solana-web` exports. Each function has one entry, with its signature, an example, its parameters and what it returns. Each entry is generated from the SDK's declarations and TSDoc when this site is built, so it matches the package. The guides show how the functions fit together. This section is where you look one up. Every mention of an export elsewhere on the site links to its entry here. ## Functions | Export | What it does | | ------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------- | | [`loadNimbusSdk`](https://sdk.nimbusprivacy.xyz/reference/load#loadnimbussdk) | Loads the SDK for a cluster.
