Splice
Splice is a New York City-based music creation platform founded in 2013 by Steve Martocci and Matt Aimonetti that operates a royalty-free sample marketplace, a rent-to-own plugin store, and a growing suite of in-house instruments, AI tools, and DAW integrations for producers and beatmakers. Splice Sounds offers a credit-based subscription giving access to millions of cleared samples, loops, presets, and MIDI; Splice INSTRUMENT is the company's virtual instrument with free monthly preset drops; Astra is a Splice-built hybrid synthesizer covering virtual analog, wavetable, sampling, granular, and FM synthesis; Beatmaker is its drum-machine instrument; and Bridge is a free plugin that surfaces the Splice Sounds catalog directly inside Ableton Live, Studio One, Pro Tools, and Studio Pro with automatic key and tempo matching. Splice has also rolled out generative AI features including Create Mode (build "Stacks" from any loop), Variations (regenerate any Splice sample with creator compensation), Craft (turn catalog sounds into playable instruments inside INSTRUMENT), and an upcoming Magic Fit (harmonic/rhythmic auto-matching to a session), with an announced ElevenLabs partnership for next-gen AI music tools. The company acquired Superpowered and Audiaire in 2020 and Spitfire Audio in 2025, and operates a rent-to-own marketplace of 130+ third-party plugins (Serum 2, V Collection, Abbey Road, etc.). Splice does not publish a public developer API, SDK, or webhook surface; the business is a consumer/prosumer SaaS for music creators, distributed via desktop app, mobile app, and DAW plugin integrations rather than a programmable platform.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Splice the way a machine reads it — 1 machine-readable artifact, 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 — Splice scores 10.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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 Splice
Each block below is one kind of artifact we hold for Splice. 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.
Security Posture 1
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.
