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.

Verify a value yourself

curl -s https://app.flopsindex.com/v1/price/FLOPS-H100-OD | jq
#   value:            2.95            (USD/GPU-hr, 2dp)
#   unit:             USD/GPU-hr
#   as_of:            2026-07-13T12:00:00Z   (delayed to a ~6h grid: 00/06/12/18 UTC)
#   data_tier:        LIVE

#   disclaimer:       indicative reference; not for settlement
#   methodology_url:  /i/FLOPS-H100-OD/methodology

#   citation_url:     /cite?...
#   permalink:        /i/FLOPS-H100-OD
#   ... source-opaque public payload only.

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