pip install flopsindex

Live GPU compute pricing + LLM inference token pricing reference rates from the FLOPS Index. Single dependency-free SDK over the FLOPS HTTP API.

30-second example

from flopsindex import Client

c = Client()  # picks up FLOPSINDEX_API_KEY if set; works auth-free for public methods

# Public, auth-free — works with no API key
print(c.price("FLCI-H100"))
# {'index_id': 'FLCI-H100', 'value': 2.45, 'unit': 'USD/GPU-hr',
#  'ts': '2026-05-17T14:00:00+00:00', 'tier': 'LIVE',
#  'confidence': 'HIGH', 'verify_url': '...', 'citation_url': '...'}

print(c.timeseries("FLCI-H100", "7d"))   # ≤200 decimated points
print(c.search("h100 spot"))             # NL → canonical slugs
print(c.methodology("flci-h100", "v0.9"))  # versioned methodology + frontmatter

Authentication

The SDK reads an API key from FLOPSINDEX_API_KEY:

export FLOPSINDEX_API_KEY="flops_xxxxxxxxx"

Or pass directly:

c = Client(api_key="flops_xxxxxxxxx")

Auth-free methods (work without a key): price, timeseries, search, methodology, methodologies, verify.

Partner-tier methods (require a key): catalog, index_current, index_history, compute_margin, recompute_audit.

If you call a partner-tier method without a key, you'll get FlopsAuthError. Public methods always work — the API key just unlocks higher rate-limit tiers when you have one.

Citation in code

When citing a FLOPS price in code, contracts, or research, ALWAYS include the methodology version (every response carries it under methodology_version):

tick = c.index_current("FLCI-H100")
print(f"Settled at ${tick['current_value']:.2f}/GPU-hr per "
      f"{tick['methodology_version']}")
# Settled at $2.45/GPU-hr per flci-h100@v0.9

The version is the contract anchor — partner replays + recompute audits pin against it.

Methods

Method	Auth	Returns
price(index_id)	none	latest tick
timeseries(id, range)	none	decimated points (≤200)
search(q)	none	NL → slug results
methodologies()	none	list of all methodologies
methodology(slug, version)	none	one methodology doc (markdown + JSON)
verify(id, value)	none	does the value match our tick?
catalog()	partner	full envelope w/ methodology_version
index_current(id)	partner	partner-tier per-index lookup
index_history(id)	partner	up to 720 historical ticks
compute_margin(...)	partner	derived: price − power − rack
recompute_audit(...)	partner	audit receipts (IOSCO substrate)

Naming conventions

• FLCI-{model} — composite spot+OD+DePIN
• FLOPS-{model}-{OD|SPOT|DEPIN} — single-tier specific
• ITPI-{model_id}-{INPUT|OUTPUT} — inference token pricing
• CLRI-{model}-{tenor} — forward / term rates (partner-tier only)

Use c.search() if you don't know the exact slug.

Errors

from flopsindex import Client, FlopsNotFoundError, FlopsAuthError

c = Client()
try:
    tick = c.price("FLCI-UNKNOWN")
except FlopsNotFoundError as e:
    print(f"index not found: {e.detail}")

Hierarchy: FlopsError → FlopsAuthError / FlopsNotFoundError / FlopsRateLimitError / FlopsServerError. All errors carry .status_code and .detail.

Not the MCP server

flopsindex (this package) is a HTTP client SDK. The MCP server for AI agents is a separate package: pip install flopsindex-mcp. See https://github.com/zeroatflops/flopsindex-mcp for that one.

Methodology

Every published price is backed by a versioned methodology document. Citation hooks live at:

https://app.flopsindex.com/v1/methodology/{slug}/{version}

For example, https://app.flopsindex.com/v1/methodology/flci-h100/v0.9.
