flopsindex
Public, source-opaque reference-rate SDKs and MCP server for FLOPS compute price indices — every value carries a verify URL.
Documentation
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
# 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.
A partner tier with higher fidelity and expanded coverage is available — contact `team@flopsindex.com`.
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`).
