CME Group is the world's largest derivatives exchange and operator of the CME, CBOT, NYMEX, and COMEX markets, offering futures and options across interest rates, equity indexes, foreign exchange, energy, agricultural products, and metals. CME Group exposes a portfolio of REST and streaming APIs through its Data Services Portal - including CME Reference Data API, Real-Time Futures and Options Data API, CME Term SOFR API, FedWatch API, Greeks and Implied Volatility API, EUR/USD Cross Currency Basis Index API, the CME ClearPort API for OTC trade submission, and iLink/MDP 3.0 connectivity to CME Globex for execution and market data.
CME Group is listed with 7 APIs on the APIs.io network. Tagged areas include Capital Markets, Derivatives, Exchange, Financial Markets, and Futures.
CME Group’s developer surface includes authentication, changelog, sandbox, API reference, signup flow, developer portal, documentation, and 27 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Securities & Market Data regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
8 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
