# Embedding/RAG Cost Estimator

> Free tool #17

Project the cost of embedding your corpus once and searching it every month — the embedding spend behind a RAG pipeline, before storage or retrieval compute.

## Three ways to use it

**Web** — the interactive page: https://telemeter.ai/tools/rag-cost-estimator

**MCP** — a `tools/call` on the public MCP server at https://telemeter.ai/mcp (tool name: `rag-cost-estimator`), read-only, no key required.

**REST** — `POST https://telemeter.ai/api/tools/rag-cost-estimator` with a JSON body matching the input schema below:

```json
