flopsindex

Reference rates for compute economics — public price indices for GPU rentals (spot, on-demand, DePIN). Every published value carries a verify URL your code can check against the public index.

Try it in one line

bash

# MCP server (Claude Code, Cursor, Windsurf, ChatGPT desktop, ...)
pip install flopsindex-mcp && claude mcp add flopsindex -- flopsindex-mcp

# Python REST SDK
pip install flopsindex

# TypeScript / JavaScript SDK
npm i @flopsindex/sdk

# Or skip install — hit the hosted MCP gateway
# https://app.flopsindex.com/mcp   (anonymous, zero-config)

Or to your agent: "Get me the current FLOPS price for an H100 on-demand and show me the verify URL."

What's distinctive

Source-opaque by contract. Every public payload returns a value plus citation and verify URLs — nothing about how the value was produced.

One surface, two access modes.

Anonymous → delayed public price for the published FLOPS index family (FLOPS-{model}-{OD|SPOT|DEPIN}), delayed onto a ~6h grid (as_of snaps to 00/06/12/18 UTC). Indicative reference — not for settlement. The citation surface, designed for LLM/agent discovery and academic reference. The family spans many accelerator models (NVIDIA data-center and workstation GPUs plus AMD Instinct), not just H100 — enumerate the live set via /v2/catalog/public; it grows as coverage crosses the ≥3-source floor.
Keyed (X-FLOPS-Api-Key) → the same five tools at full precision.

Features

Five key-free tools — list_indices, search_indices, get_price, get_index, verify. No API key, no signup, no configuration.
Every value carries a verify URL — check any published number against the index from your own code. verify returns whether a cited value matches.
Spot, on-demand and DePIN reference prices per chip and market type.
Three vendors — NVIDIA data-center and workstation GPUs, AMD MI300X, and Intel Gaudi 2. Enumerate the live set via /v2/catalog/public.
Source-opaque by contract — the value plus citation and verify links, never the inputs behind it.
Delayed onto a ~6h grid (00/06/12/18 UTC), 2dp values, banded 24h change, label confidence. Indicative reference — not for settlement.
Zero install or local — hosted MCP gateway at https://app.flopsindex.com/mcp, or uvx flopsindex-mcp.
SDKs included — Python (flopsindex), TypeScript (@flopsindex/sdk), and LangChain / LlamaIndex (langchain-flopsindex).

What's in this repo

Path	What
`mcp/`	The `flopsindex-mcp` server — stdio MCP, 5 public tools (`list_indices` · `search_indices` · `get_price` · `get_index` · `verify`) + a `flops://index/<INDEX_ID>` resource. Published on PyPI.
`sdk/python/`	The `flopsindex` Python REST SDK — published on PyPI.
`sdk/typescript/`	The `@flopsindex/sdk` TypeScript / JavaScript REST SDK — published on npm.
`schema/`	`compute-index-spec.v0.1` — the public payload schema (JSON Schema) + a worked example.
`openapi.json`	OpenAPI 3 description of the public surface.
`llms-full.txt`	Extended public-surface reference for LLM/agent discovery — source-opaque, 6 endpoints, 14-field envelope. Mirror of the hosted `/llms-full.txt`.

The same value is reachable via the SDK and via the MCP get_index tool — every path returns the same source-opaque payload.
