Wire FLOPS into your agent, pipeline, or dashboard
GPU compute + inference reference prices via a 5-tool public MCP server, an auth-free REST surface, and a stdlib-only Python SDK. Receipts are SHA-256 + content-addressed — every published value is verifiable end-to-end without trusting the server.
The agent path. flopsindex-mcp on PyPI and the hosted server at https://app.flopsindex.com/mcp expose 5 public tools over MCP — every published value is one tool call away. Auth-free, no key required.
Install
pip install flopsindex-mcpWire to your host

| tool | what it does |
|---|---|

Public surface — auth-free LIVE indices for prototyping, llms.txt discovery, and agent.json contract.

}A partner/pilot tier with deeper feeds + tools — full catalog, history, spreads, custom indices, and the recompute audit substrate — is available. Contact partners@flopsindex.com with your use case.
pip install flopsindex
from flopsindex import FlopsClient
c = FlopsClient() # no key needed for the public surface
c.price("FLOPS-H100-OD") # current public reference price
c.search("H100") # NL-to-slug
c.verify("FLOPS-H100-OD", 6.155) # confirm a value
c.catalog_public() # public index catalogExcel / Sheets cells
Same data, formula syntax. See the finance onboarding for the cell catalog.
Do I need an API key for the public surface?
GET /v1/price/{slug}, search, verify, the citation page /i/{slug}, and the public catalog are auth-free. A partner/pilot tier with deeper feeds + tools is available — contact partners@flopsindex.com.What does verify actually do?
GET /v1/verify?index_id={id}&value={value} returns {verified, actual_value, delta_pct, source_url} — it confirms a published value is real and re-derivable from its source vector. Full audit replay from canonical inputs is part of the partner/pilot tier.Are the public endpoints rate-limited?
Retry-After. Hammer-respect is documented in /.well-known/agent.json.Is each published value re-derivable?
methodology_version pin and an SHA-256 observations_hash. Methodology versions are immutable, so a value always re-derives from that version's math even after the current version advances.
