Starkware
StarkWare Industries builds STARK-proof (Scalable Transparent ARgument of Knowledge) blockchain scaling technology for Ethereum. Its flagship products are Starknet, a permissionless decentralized validity-rollup (ZK-Rollup) where developers deploy Cairo smart contracts, and StarkEx, an application-specific scaling engine for exchanges (spot, perpetual, NFT, and payments). The developer surface centers on the Starknet Node JSON-RPC API (read, write, trace, and WebSocket methods specified in OpenRPC), a Wallet JSON-RPC API, a Proving API, StarkEx REST gateways, first-party SDKs (starknet.js, starknet.py, starkex-js), the starkli CLI, and the Cairo programming language and prover stack (Stwo, Cairo VM). This profile catalogs those machine-readable specs and developer artifacts for the API Evangelist network.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Starkware the way a machine reads it — 8 machine-readable artifacts across 4 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 — Starkware scores 37.0/100 (thin), with a separate agent-readiness read of 39/100 (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.

How we profile Starkware
Each block below is one kind of artifact we hold for Starkware. 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 4
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.
Starknet Node JSON-RPC API
The Starknet full-node JSON-RPC API (OpenRPC), covering read methods (blocks, transactions, state, classes, events, fees), write methods (add invoke/declare/deploy-account trans...
Starknet Wallet JSON-RPC API
The Starknet wallet JSON-RPC API (SNIP-based) that dApps use to talk to browser/extension wallets: request accounts, permissions, chain switching, typed-data signing, and submit...
Starknet Proving API
The Starknet proving JSON-RPC API for submitting transactions to be proven by the STARK prover.
StarkEx REST API
StarkEx application-specific scaling engine REST API for spot and perpetual trading systems, exposing Gateway, Feeder Gateway, and Availability Gateway endpoints plus documented...
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVEREvent 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 2
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.
