Cache the Gemini SDK in your email drafting tool with Crowkis

Building email drafting tools on the Gemini SDK? Add a semantic cache so similar drafts requested over and over stop costing full price.

Email drafting tools built on the Gemini SDK share one problem: similar drafts requested over and over. Each repeat is a full-price the Gemini SDK call for an answer you already have.

Put a semantic cache in front. Point the Gemini SDK's base URL at the Crowkis OpenAI-compatible gateway, or wrap the call in get-or-compute, and reworded repeats are served from cache, no rewrite of your email drafting tools logic.

the Gemini SDK + Crowkis

base_url = "http://127.0.0.1:6380/v1"   # Crowkis gateway, semantic cache in front

In plain words: The email drafting tools keep working exactly as before; the repeats just stop hitting the model.

On repetitive traffic this cuts costs up to 60-70% on repetitive workloads, and every hit carries a confidence score so reuse stays safe. Drop it in over RESP, gRPC, REST, or MCP, no rewrite required.
