@apicity/free-media-upload

Zero-auth file hosting wrapper for catbox, gofile, uguu, filebin, litterbox, tempsh, tflink, and tmpfiles — eight providers behind one typed surface.

Installation

npm install @apicity/free-media-upload
# or
pnpm add @apicity/free-media-upload

Quick Start

import { free-media-upload as createFree-media-upload } from "@apicity/free-media-upload";

const free-media-upload = createFree-media-upload({ apiKey: process.env.FREE-MEDIA-UPLOAD_API_KEY! });

Real-world example: race a portrait across four free hosts

@apicity/free-media-upload wraps eight zero-auth, no-account file-hosting endpoints behind one typed surface — the win is being able to fan the same Blob out to multiple hosts in parallel, then pick whichever URL came back first (or any survivor) without rewriting four different multipart callers. The snippet below uploads a single 84 KB JPEG to the four richest response shapes — catbox (plain string), gofile (rich bundle metadata), uguu (random-rename + dupe detection), filebin (md5/sha256 + expiry) — and shows how to normalise them under one toUrl() helper.

Every URL, byte count, and hash below is mined verbatim from tests/recordings/free_2578706139/, replayed by tests/integration/free-catbox.test.ts, tests/integration/free-gofile.test.ts, tests/integration/free-uguu.test.ts, tests/integration/free-filebin.test.ts, and tests/integration/free-litterbox.test.ts.

import { readFileSync } from "node:fs";
import { freeMediaUpload as createFreeMediaUpload } from "@apicity/free-media-upload";
import type { GofileUploadResponse, UguuUploadResponse, FilebinUploadResponse } from "@apicity/free-media-upload";

// 1. The factory takes no api key — every host below is genuinely
//    auth-free and account-free. Pass `{ timeout: 60_000 }` or a
//    custom `fetch` if you need to override the defaults.
const freeMediaUpload = createFreeMediaUpload();

const bytes = readFileSync("./cat1.jpg"); // 83,558 bytes
const file = new Blob([bytes], { type: "image/jpeg" });

// 2. Race four hosts in parallel via Promise.all. Each returns a
//    different shape: catbox/litterbox/tempsh hand back a plain
//    `string` URL, gofile/tflink return a metadata bundle, uguu's
//    payload nests under `files[]`, and filebin splits things into
//    `bin` + `file` blocks. The factory keeps these distinctions in
//    the type system so the destructure below is statically checked.
const [catboxUrl, gofile, uguu, filebin] = (await Promise.all([
  free.catbox.upload({ file, filename: "cat1.jpg" }),
  free.gofile.upload({ file, filename: "cat1.jpg" }),
  free.uguu.upload({ file, filename: "cat1.jpg" }),
  free.filebin.upload({ file, filename: "cat1.jpg", bin: "apicity-test-img" }),
])) as [string, GofileUploadResponse, UguuUploadResponse, FilebinUploadResponse];

// 3. catbox is the simplest UX: text/plain response, just the URL,
//    permanent until the operator deletes it. Good for a 'host once,
//    forget' public asset.
console.log(catboxUrl);
// → "https://files.catbox.moe/0ufdor.jpg"

// 4. gofile is the only host that gives you a sharable download page
//    (suitable for human consumption) plus a CDN-direct id you can use
//    to build APIs against. The `parentFolderCode` is a 6-char folder
//    handle — every upload lands in a fresh anonymous folder unless
//    you authenticate.
console.log(gofile.data.downloadPage);
// → "https://gofile.io/d/hmoMxW"
console.log(gofile.data.id, gofile.data.md5, gofile.data.size);
// → "a7feccb4-96b4-4b2c-923a-832106388ad6" "391a26048ce697ba072acd83209923f7" 83558

// 5. uguu rewrites filenames to a random 8-char slug to stop URL
//    enumeration, and tells you whether your bytes were already on
//    the host (`dupe: true`) so you can skip a re-upload next time.
//    Note the `files[]` array — uguu accepts batched uploads via the
//    same endpoint, even though @apicity/free-media-upload only ships single-file.
console.log(uguu.files[0].url, uguu.files[0].dupe);
// → "https://n.uguu.se/GeNMsbBp.jpg" false

// 6. filebin verifies content integrity for you — it returns both
//    md5 and sha256, plus an expiry. The `bin` is a namespace you can
//    re-upload into to grow a multi-file bundle (omit `bin` and you
//    get an auto-generated one). Files in a bin expire together on
//    `bin.expired_at`.
console.log(filebin.file.md5, filebin.file.sha256);
// → "ORomBIzml7oHKs2DIJkj9w==" "561dbe5dcd0c931cd3b41705ebe00df9181560967cea8b17128373a06ab911a3"
console.log(`bin "${filebin.bin.id}" expires ${filebin.bin.expired_at}`);
// → 'bin "apicity-test-img" expires 2026-04-23T07:19:25.458442Z'

// 7. Hosts that return strings already give you a URL; hosts that
//    return JSON bury it under different keys. A tiny normaliser lets
//    downstream code stop caring which host won the race.
function toUrl(
  res: string | GofileUploadResponse | UguuUploadResponse | FilebinUploadResponse,
  bin?: string,
  filename?: string,
): string {
  if (typeof res === "string") return res;
  if ("data" in res) return res.data.downloadPage;       // gofile
  if ("files" in res) return res.files[0].url;           // uguu
  return `https://filebin.net/${bin}/${filename}`;       // filebin
}

console.log([
  toUrl(catboxUrl),
  toUrl(gofile),
  toUrl(uguu),
  toUrl(filebin, "apicity-test-img", "cat1.jpg"),
]);
// → [
//     "https://files.catbox.moe/0ufdor.jpg",
//     "https://gofile.io/d/hmoMxW",
//     "https://n.uguu.se/GeNMsbBp.jpg",
//     "https://filebin.net/apicity-test-img/cat1.jpg",
//   ]

Failover across ephemeral hosts

When you only need a URL to live for a few hours — typically because a downstream model is about to GET it once and then forget — @apicity/free-media-upload ships a uploadToAnyHost helper that walks a randomised host list and returns the first successful URL, raising a single FreeMediaUploadError only if every host fails. Useful when one provider is flaky (uguu's CDN can 502 during traffic spikes) but you don't care which one wins.

import { free as createFree, uploadToAnyHost, FreeMediaUploadError } from "@apicity/free-media-upload";

const freeMediaUpload = createFreeMediaUpload();
const file = new Blob([bytes], { type: "image/jpeg" });

// litterbox accepts a TTL; uguu and tflink are best-effort permanent.
// uploadToAnyHost shuffles the list and tries each host sequentially,
// so a single 502 from uguu falls through to tflink without your code
// ever seeing it. The returned URL is already normalised — string in,
// string out, regardless of which host responded.
try {
  const url = await uploadToAnyHost(free, {
    file,
    filename: "cat1.jpg",
    hosts: ["litterbox", "uguu", "tflink"],
    time: "12h", // forwarded to litterbox if it wins the shuffle
  });
  console.log(url);
  // → "https://litter.catbox.moe/04obtk.jpg"  // example: litterbox won
} catch (err) {
  if (err instanceof FreeMediaUploadError) {
    // err.body.failures is a string[] of `<host>: <message>` lines —
    // useful for surfacing exactly which hosts misbehaved.
    console.error(err.status, err.body);
  }
}

Notes

• All eight endpoints take { file: Blob, filename?: string }. catbox and litterbox respond with text/plain (the URL itself); tmpfiles, uguu, gofile, filebin, and tflink return JSON; tempsh returns plain text. The factory parses each correctly so you never see the raw body — just the typed shape.
• litterbox.upload is the only endpoint with a time field — "1h" | "12h" | "24h" | "72h". Anything longer than 72h needs the permanent-host siblings (catbox, gofile, filebin).
• filebin.upload is the odd one out: it's a binary POST (no multipart wrapper), so the Blob goes on the wire as-is and the server treats <bin>/<filename> as the upload target. Re-uploading to the same bin adds the file to the bundle rather than replacing it; pre-create a stable bin slug to grow a multi-file collection.
• gofile's guestToken is the closest thing this provider has to an auth handle — save it if you want to delete the upload later via the gofile API. Without it, anonymous uploads are write-only.
• Every endpoint exposes a Zod schema: free.catbox.upload.schema.safeParse(input) validates the payload before the network call, which catches the most common mistake (passing a Buffer or string instead of a Blob).
• All endpoints accept an AbortSignal second argument and compose with withRetry / withFallback from @apicity/free-media-upload's middleware re-exports — useful for ride-out 429s on uguu or chaining gofile → catbox as a fallback pair.
• Errors throw FreeMediaUploadError with status and the parsed body attached: try { ... } catch (e) { if (e instanceof FreeMediaUploadError) console.error(e.status, e.body); }.
