Why fetch when you can just
GRAB?
Generate Request {to: API from: Browser}
Debugging fetch requests is a bitch. Make the switch!
Functionally Brilliant, Elegantly Simple. One function, no dependencies, minimalist syntax with more features than alternatives.
npm i grab-url
GRAB is the FBEST Request Manager: Functionally Brilliant, Elegantly Simple Tool
23+ features packed into 4KB. No bloat, no dependencies, just pure functionality.
Auto-JSON Convert
Pass parameters and get response or error in JSON, handling other data types automatically.
Reactive Loading
Sets .isLoading=true on response object for React, Vue, Svelte — any framework works.
Debug Logging
Global log() prints colored JSON structure, response timing. Ctrl+I opens DevTools overlay.
Mock Server
Configure grab.mock for dev/testing. Supports conditional responses and delays.
Cancel Duplicates
cancelOngoingIfNew or cancelNewIfOngoing prevents request cascading.
Timeout & Retry
Configurable timeout (default 30s) with retryAttempts for auto-retry on failure.
CLI Testing
npm i -g grab-url for command line API testing with params and JSON payloads.
Request History
All requests stored in grab.log for debugging and analytics.
Infinite Scroll
Built-in pagination that auto-loads and merges next page on scroll.
Instance Config
Create separate instances with grab.instance() for different APIs.
Frontend Cache
Set cache: true for instant repeat requests from browser memory.
Regrab On Error
Auto-retry on timeout, window refocus, network change, or stale data.
Framework Agnostic
Works anywhere — React, Vue, Svelte, vanilla JS. No lifecycle hooks needed.
TypeScript Tooltips
Full type inference with hover tooltips and autocomplete for options.
Rate Limiting
Built-in rate limiting prevents multi-click cascading responses.
Request Hooks
Global onRequest interceptor for auth headers and request modification.
File Upload
FormData support with base64 conversion option for JSON APIs.
Jest Testing
Easy unit testing with mock setup and grab.log assertions.
Proxy Support
Node.js proxy support with HttpsProxyAgent for server-side requests.
Repeat & Poll
Repeat request X times or poll every X seconds for live updates.
Auto-Unzip
Automatically extracts ZIP responses into { data: { filename: content } }. Set unzip: false to disable.
DOM Parsing
Automatically parses HTML responses. Pass dom: "selector" for CSS extraction or dom: false to disable.
OpenAPI SDKs
Generate a typed client or MCP server from any OpenAPI spec — every endpoint gets caching, retries and mocks.
Simple Syntax, Powerful Results
Why fetch things when you can just GRAB? One function handles everything — JSON conversion, loading states, caching, retries, and more.
import grab from 'grab-url';
// Simple GET request
const data = await grab('users');
// POST with auto-JSON
await grab('users', {
post: true,
email: 'jane@example.com',
age: 25
});
// GET with query parameters
const searchResults = await grab('search', {
query: 'javascript',
page: 1,
limit: 10

Partial support or requires additional configuration
One Spec, Two Ways to Ship
Point either generator at any OpenAPI spec. Both send requests through grab, so every endpoint gets caching, retries, rate limiting, dedupe and mocks for free.
For your app
Typed Client SDK
Generate a fully typed TypeScript SDK from an OpenAPI spec with Hey API, wired to send every request through grab instead of axios or fetch.
npx heyapi-grab ./openapi.yaml ./src/clientFor AI agents
MCP Server
Generate a production-ready MCP server from the same spec with the mcp-use framework, so Claude, ChatGPT and other agents can call your API as a tool.
npx api2ai ./openapi.yaml ./my-mcp-server
