Use FLOPS in 10 Minutes
Settlement-grade GPU compute price indices, delivered through whichever surface fits how you work — a spreadsheet cell, an agent on Claude or Cursor, or a one-line cURL. Every published value carries a cryptographic receipt your code can verify.
The fastest path for finance teams already in a spreadsheet. The add-in registers =FLOPS.PRICE() for the current public reference price of any index.

The agent path. flopsindex-mcp is on PyPI and the public server exposes 5 tools over MCP — list_indices, get_index, get_price, search_indices, and verify — so your agent answers "what's the H100 price?" or "verify this value" without leaving the chat. Auth-free, no key required.
Install
pip install flopsindex-mcp

Don't want to manage a local process? Point the host at https://app.flopsindex.com/mcp — it speaks the MCP transport directly, no install required.
Try it
- "What's the current H100 on-demand index?"
- "Search for B200 spot indices."
- "Verify that FLOPS-H100-OD is currently 6.15."
- "What inference token price indices are published?"
The lowest-level path. The auth-free public surface serves the current global reference price for each published index — no signup.

| SLUG | WHAT IT MEASURES |
|---|---|
| FLOPS-H100-OD | H100 SXM5 on-demand $/GPU-hr — the canonical compute reference |
| FLOPS-H100-SPOT | H100 spot/marketplace price — preemptible counterparty |
| FLOPS-B300-OD | Blackwell B300 on-demand — frontier silicon settlement |
| FLOPS-H100-DEPIN | H100 via decentralized GPU networks (Akash / io.net / Targon) |
| FLOPS-llama-3.1-70b-INFERENCE_OUTPUT | Output token price (USD/1k tokens) across hosted providers |
| FLOPS-B200-SPOT | Blackwell B200 spot/marketplace price — preemptible frontier |
Is the public surface really auth-free?
GET /v1/price/{slug}), search, verify, the citation page /i/{slug}, and the public catalog need no signup and no key. A partner/pilot tier with deeper feeds + tools is available — contact partners@flopsindex.com.What does "k-anonymity ≥ 3" mean?
How do I verify a published value?
GET /v1/verify?index_id=FLOPS-H100-OD&value=6.155 → {verified, actual_value, delta_pct, source_url}. Each published value also carries a methodology_version so you can cite the exact math that backed it.What does the methodology version control?
flops-h100-od@v0.9). A methodology change never silently rewrites history — the new version pins at the change moment and old values keep their old version. Methodology versions are immutable.
