About this repository

This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.

Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema, apis.json, llms.txt and similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.

The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.

Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.

  • Something wrong? Open an issue on this repository, or email info@apievangelist.com.
  • Published something new? Ask for a re-score and we will re-run the rating.
  • Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.

Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.

Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for:

  • A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account.
  • A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody.
  • Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here.
  • Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it.

This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down.

On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.

Full detail: Where this data comes from

Split, now part of Harness Feature Management and Experimentation, is a feature flag and experimentation platform that enables teams to safely release features with controlled rollouts and measure their impact. Their developer platform provides REST APIs for managing feature flags, environments, segments, and workspaces, along with SDKs for evaluating feature flags across multiple languages and platforms.

APIs

Split Admin API

The Split Admin API is a REST API that enables programmatic management of workspaces (projects), environments, traffic types, attributes, users, groups, API keys, and change requests within the Split platform (now Harness Feature Management and Experimentation). The API uses resource-oriented URLs, returns JSON responses, and requires Admin API keys for authentication. All endpoints are prefixed with /internal/api/v2 on the api.split.io host.

  • Administration
  • Experimentation
  • Feature Flags
  • Feature Management

Properties

Split Feature Flag API

The Split Feature Flag API provides endpoints for creating, editing, and deleting feature flags (splits) and their definitions within specific environments. Developers can use this API to define treatments, configure targeting rules, set percentage-based rollouts, and manage feature flag lifecycles programmatically.

Tags

  • Feature Flags
  • Rollouts
  • Targeting
  • Treatments

Properties

Split Evaluator API

The Split Evaluator is an HTTP service that wraps Split SDKs to provide feature flag evaluation via a REST API. It enables applications that cannot directly embed an SDK to request treatment evaluations over HTTP, making it suitable for architectures where a centralized evaluation service is preferred.

Tags

  • Evaluation
  • Feature Flags
  • Microservices
  • Treatments

Properties

Split JavaScript SDK

The Split JavaScript SDK provides client-side integration for feature flag evaluation in browser-based applications. It handles real-time feature flag synchronization, treatment evaluation, event tracking, and impression management.

Properties

Split Node.js SDK

The Split Node.js SDK enables server-side feature flag evaluation for Node.js applications with local evaluation, automatic synchronization, event tracking, and impression logging.

Properties

Split Java SDK

The Split Java SDK provides server-side feature flag evaluation for Java and JVM-based applications with local treatment evaluation and streaming updates.
