## What APIKumo is

APIKumo is a calm, single-workspace tool for the whole API lifecycle:
designing HTTP requests, automating auth and assertions with pre/post
processors, versioning your work, and publishing typed docs to a custom
subdomain with an AI assistant and a Model Context Protocol (MCP) endpoint
built in.

It runs in the browser, syncs to your account on Supabase, and is free
while in preview.

## Features

- **Send any HTTP request.** Method, URL, query, headers, body, and auth in
  one focused editor. Bearer, Basic, and API-key auth ready out of the box.
- **Monaco-powered editor.** JSON, XML, plain text, HTML, JavaScript,
  GraphQL, and binary bodies — the same syntax engine that powers VS Code.
- **Collections and tabs.** Nested folders, multi-tab editing, right-click
  context menus, and a Cmd+K palette to jump to any saved request in one
  keystroke.
- **Environments with `{{variables}}`.** Local, Staging, Production —
  switch in one click. Variables resolve at send-time so saved requests
  never leak secrets.
- **Pre & post processors.** HMAC signing, timestamp nonces, JSONPath
  extraction, status assertions, custom JS — chain steps before send and
  after response.
- **Schemas, typed both ways.** Describe request and response shapes with a
  structured schema editor — fields, types, enums, examples — surfaced
  inline in docs.
- **Auto-generated docs.** Every saved request becomes a docs page.
  Method, URL, parameters, schemas, and the latest response — no extra
  writing required.
- **Publish to a subdomain.** Make any collection public on its own
  subdomain, with custom theme, search, scroll-spy, and shareable
  per-endpoint permalinks.
- **Versions and changelog.** Snapshot a collection, edit the next version
  safely, and surface a changelog modal to your readers when you ship.
- **AI docs chat.** Readers ask questions about your API in plain English;
  answers are grounded in your live docs and cite the relevant endpoint.
- **MCP endpoint, ready.** Every published collection exposes a Model
  Context Protocol endpoint so Claude, Cursor, and other AI tools can call
  your API.
- **Code samples in 20+ targets.** cURL, Fetch, Axios, Python Requests, Go,
  Java, Swift, PHP, C#, Ruby, R — generated from the live request, env
  vars substituted.
- **Cloud sync, RLS-secured.** Changes are debounced and synced to your
  account on Supabase, secured by row-level policies.
- **CORS-free in dev.** Local requests route through the dev proxy so the
  browser never blocks them.
- **Copy anywhere.** One click to copy a request as a shell-ready cURL
  line or a fetch snippet, with environment variables already substituted.

## Publish

Every collection can become a public docs site on its own subdomain, with
search, scroll-spy navigation, and live try-it. No static-site generator,
no markdown rewriting.

- **Custom subdomain.** Publish to `your-api.docs.example` and share a
  single link.
- **Versions & changelog.** Snapshot v1.0, keep editing v1.1, and show
  readers what changed.
- **Permalinks everywhere.** `/endpoints/users-create`, plus llms.txt,
  OpenAPI, and Markdown exports of the same docs.
- **Try-it panel.** Readers can call your API from the docs page, with
  env-aware variables and auth.

## Automate

Pre- and post-processors handle the work between "press Send" and "got a
response":

Pre-processors (run before send):

- Bearer from env — read `{{token}}` into Authorization.
- HMAC signature — sign the body with SHA-256 / SHA-512 / SHA-1 / MD5.
- Timestamp + nonce — set `X-Timestamp` / `X-Nonce` headers.
- Base64-encode body, conditional skip, custom JS sandbox.

Post-processors (run after response):

- Extract token (e.g. `$.access_token` → env.token).
- Extract by regex / JSONPath / header into a variable.
- Assert status range, assert body value.
- Log response (pretty / raw) into the Console panel.
- Custom JS sandbox.

Variables you capture in one request flow into the next, so you can chain
auth → list → delete in a single workspace.

## AI-native

- **Docs chat, grounded.** Built-in assistant on every published docs site.
  Answers are grounded in live endpoints and cite the exact request.
- **MCP endpoint, automatic.** Every collection exposes an MCP server, so
  Claude, Cursor, and Continue can read your surface and call it.
- **llms.txt + Markdown.** One-click export of your docs in LLM-friendly
  formats.
- **Try-it that survives auth.** Readers run real calls from the docs
  page, with env-aware variables and the same auth processors you use in
  the workspace.
- **OpenAPI export.** Your collection compiles to a clean OpenAPI 3
  document.
