Bitnomial
Bitnomial is a Chicago-based derivatives exchange company that owns and operates U.S. CFTC-regulated subsidiaries — a Designated Contract Market (exchange/DCM), a Derivatives Clearing Organization (clearinghouse/DCO), and a Futures Commission Merchant (clearing brokerage/FCM). It offers leveraged spot, perpetuals, futures, options, and prediction markets on a single regulated venue with crypto margin and settlement. For developers, Bitnomial publishes a public HTTPS REST API (products, orders, fills, block trades, indexes, funding rates, market stats), a real-time WebSocket market-data feed (trade, book, block, status channels), a low-latency binary order-entry protocol (BTP), and a FIX 4.4 API with dropcopy. REST authentication uses HMAC-SHA256 request signing with per-connection credentials. Surfaced as a portfolio company of Electric Capital and enriched by the API Evangelist pipeline.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Bitnomial the way a machine reads it — 6 machine-readable artifacts across 2 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Bitnomial scores 40.1/100 (developing), with a separate agent-readiness read of 19/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Bitnomial
Each block below is one kind of artifact we hold for Bitnomial. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 2
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Bitnomial Exchange REST API
Public HTTPS REST API for the Bitnomial exchange — products and contract specs, orders, fills, block trades, indexes, funding rates, and market statistics. HMAC-SHA256 signed au...
Bitnomial Market Data WebSocket API
Real-time WebSocket market-data feed delivering trade, order book, block trade, and market status messages for subscribed products.
Event Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Bitnomial, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
