Documentation Overview

apipriceindex-mcp

An MCP server that gives any AI agent live, verified LLM API prices.

Ask your assistant "what would 200M input / 15M output tokens a month cost me on Sonnet vs GPT?" and it answers from today's index — every price with its verification date, cross-check confidence and source URL. Data from apipriceindex.com (CC BY 4.0, re-checked daily against official pricing pages).

Tools

Tool	What it does
`search_models`	Find model ids by name/provider, filter by context window or open weights
`get_price`	Verified price of one model: input/output/cached input USD per Mtok, `verified_at`, `confidence`, source
`estimate_cost`	Monthly bill of a workload; ranks chosen models — or the whole catalog — cheapest first

Install

Terminal

pip install apipriceindex-mcp

Claude Code / Claude Desktop:

Terminal

claude mcp add apipriceindex -- apipriceindex-mcp

Or in any MCP client config:

config.json

{ "mcpServers": { "apipriceindex": { "command": "apipriceindex-mcp" } } }

Behavior

Prices are fetched live from the index (15-minute in-memory cache) — never stale training data.
Index unreachable → explicit error. No cached or invented price is ever served silently.
Index older than 14 days → answers still come, with a warning pointing at the index's health endpoint.
Model not tracked → says so, links the dataset. No price invented.
Cache discount only where the provider publishes a cached-input price.
Cost only: the index does not rank model quality, and third-party benchmark scores are not redistributed.

Environment: APIPRICEINDEX_URL overrides the dataset URL (testing).
