# SDK downloads

Install the review release locally and inspect the contract behind it.

## Release 1.1.0

| Artifact | Installation |
| --- | --- |
| [TypeScript package](/downloads/thesauros-sdk-1.1.0.tgz) | `npm install ./thesauros-sdk-1.1.0.tgz` |
| [Python wheel](/downloads/thesauros-1.1.0-py3-none-any.whl) | `python -m pip install ./thesauros-1.1.0-py3-none-any.whl` |
| [SHA-256 checksums](/downloads/SHA256SUMS) | Compare the downloaded file with its listed checksum |
| [Partner OpenAPI](/openapi/partner-openapi.json) | Current Partner API contract |
| [Sandbox OpenAPI](/openapi/sandbox-openapi.json) | Separate simulated Earn API contract |

These packages are local review artifacts, not a registry publication. Both include `PartnerClient` and `SandboxClient`; the original `Thesauros` sandbox name remains compatible.

## Compatibility

Use TypeScript on Node 18+ with `fetch` and ESM, or Python 3.9+. Both clients have zero runtime dependencies. The TypeScript package includes declarations; the Python wheel includes TypedDict models and `py.typed`.

Partner methods were exercised against a local test backend across all 43 operations. See the [release notes](/resources/changelog/) for behavior changes and the language guides for error handling and webhook verification.
