API Client

Cluster-based API collections with framework-aware source scanning, JSON/XML tree editors, vx scripting, response documentation, real-time team sync, and a public marketplace.

Concepts

Term	Meaning
Cluster	A collection of requests, like a Postman collection — but with built-in description, documentation, variables, auth, and team sharing.
Folder	Logical grouping inside a cluster.
Request	A single HTTP call (or a special VAR/AUTH/OVR record).
Nexus	A team workspace that owns clusters and shares them with members in real time.
Variable / Auth / Override	Special "request types" that store reusable values (`{{baseUrl}}`, bearer tokens, per-environment overrides).

Methods supported

GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS — plus the special types VAR, AUTH, and OVR.

Request editor

URL bar with method selector and live {{variable}} resolution.
Headers editor with autocomplete on 40+ standard header names and per-key value suggestions (Content-Type → MIME list, etc.).
Body modes: raw (JSON, XML, text), form-data (text + file uploads), none.
Query parameters tab.
Per-request timeout setting.
Pre-request & test scripts — see vx Scripting.

KV value colorization

Header/param/body rows are syntax-coloured live as you type:

{{variables}} — green if resolved, red if missing, hover shows the resolved value.
Bearer / Basic / Token prefixes — pink.
MIME types — green; URLs — blue; UUIDs — purple; emails — purple; phone numbers — cyan.
true — green; false — red; numbers — yellow; dates — cyan.

Cluster overview tab

Click the cluster header to open a 3-section overview:

Description — rich-text editor with toolbar (bold, italic, lists, headings, links, code) and an AI Generate Description button.
Documentation — endpoint reference, exports, connected repository, AI-generated docs — see Response Docs.
Requests — the standard request tree.

The right-side stats sidebar shows live counts: requests, folders, variables, auth, version, owner, members, your role.

Source scanner — 15+ frameworks

Connect a local repository and the source scanner extracts every endpoint. Supported: Laravel, Django, Rails, Next.js, Nuxt, Angular, Go, Rust, Java (Spring/Kotlin), .NET, Elixir, Dart, Python, PHP, Node.js. DDD-friendly route patterns include app/Domain/*. See Source Scanner.

Real-time collaboration

Cloud clusters sync via Reverb WebSocket. Edits, forks, and change requests propagate to every connected teammate instantly.

Public marketplace

Browse public clusters, fork them into your nexus, star, and subscribe — see API Marketplace.
