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).

Available Tools

5 tools
get_indexAInspect

Resolve a FLOPS index to its source-opaque PUBLIC payload (the public citation contract). Returns {index_id, value, unit, as_of, data_tier, confidence, verify_url, citation_url, permalink}. Prefer this when you intend to CITE the value. Also exposed as the MCP resource flops://index/<INDEX_ID>.

Inputs: index_id (required).

get_priceAInspect

Fetch the current published value for a FLOPS compute price index. Returns the published envelope as-is: {index_id, value, unit, as_of, delayed, data_tier, confidence, change_24h, disclaimer, methodology_url, verify_url, citation_url, permalink, upgrade} -- the 14-field envelope. Values are delayed and indicative. Use get_index for the reduced, citation-only payload.

Inputs: slug (required).

list_indicesAInspect

List all public FLOPS compute-price indices. Returns {count, indices[]} where each row is {index_id, family, value, unit, as_of, confidence, change_24h, delayed}. Use this to discover available indices before calling get_index or verify. No auth required.

Inputs: family_filter.

search_indicesAInspect

Resolve a free-text query to canonical FLOPS index slugs. Use when you don't know the exact slug — e.g. 'H100 spot' returns matching catalog entries.

Inputs: q (required), limit.

verifyAInspect

Check a FLOPS index value against the published index. Pass value with a number you are about to cite (or already hold) and the response tells you whether it is right: verified true/false, expected (what you submitted), actual_value (what FLOPS publishes) and delta_pct. Omit value to simply look up the current published value — then verified is null, which means 'not checked', NOT 'correct'. Note: without an API key you are checked against the public value, which is rounded to 2 decimals and delayed onto a 6-hour grid, so a full-precision real-time number will not match anonymously.

Inputs: index_id (required), value.

    Scored across 5 tools

    Disambiguation4/5

    Most tools are clearly distinct: list_indices and search_indices serve discovery, verify checks a submitted value, and get_price/get_index fetch values. The only potential confusion is between get_price and get_index, but their descriptions clearly differentiate (full envelope vs. citation payload), so agents can pick correctly.

    Naming Consistency4/5

    Names follow a consistent verb_noun pattern: list_indices, search_indices, get_price, get_index. The outlier is 'verify', a bare verb lacking an explicit object, but it's still readable and fits the action-oriented style. Overall the pattern is predictable with one minor deviation.

    Tool Count5/5

    Five tools is a well-scoped number for a FLOPS index service. Each tool serves a distinct purpose (list, search, verify, fetch full, fetch citation), leaving no redundant or missing core operations. The count is appropriate for the domain.

    Completeness5/5

    The set covers the full lifecycle of working with FLOPS indices: discovering available indices (list_indices, search_indices), retrieving current values (get_price, get_index), and verifying cited values (verify). No obvious gaps exist; the read-only nature of the service means no update/delete is expected. The inclusion of a citation-specific payload further completes the workflow.
