## UserAPI.ai

Midjourney has no official public API, so teams that want image generation inside their own products usually need a workaround. UserAPI.ai fills that gap as an independent, unofficial API: it accepts a prompt and returns generated images, exposing the familiar Midjourney methods as REST endpoints you can call from your backend.

There are two ways to generate. With your own Midjourney account you add a Discord token once and pay Midjourney for your plan; UserAPI access costs $0.04 per request or $25 per month, and this route is cheaper above a few hundred images a month and supports speed mode and multiple accounts. With UserAPI Cloud you need no Midjourney subscription and no Discord token — Generations run on UserAPI's accounts at $0.08 per image, with failed tasks refunded automatically, which is a fast way to test.

The service supports the core Midjourney toolkit: Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint. It ships documentation, code examples for Python, Node.js and PHP, and no-code integrations for n8n and Make.com. It is explicitly not affiliated with Midjourney Inc., so evaluate the account and reliability risks of unofficial access before building it into production.

**Pricing & Plans:** UserAPI.ai offers a free pack of 50 requests with no card. Using your own Midjourney account costs $0.04 per request or $25 per month (or $67.50 per quarter and $246 per year), while UserAPI Cloud runs on UserAPI's accounts at $0.08 per image, a 60% discount off the $0.20 launch rate, starting from $3 (about 37 images), with failed tasks refunded automatically.

- **Full Midjourney method coverage:** Call Imagine, Upscale, Variation, Blend, Describe, Animate, Upsample, Pan and Inpaint through a REST API for scripted image generation.
- **Cloud generation without Discord:** Generate without a Midjourney subscription or Discord token by running on UserAPI Cloud accounts, with failed tasks refunded automatically.
- **Multi-account admin panel:** Manage multiple image generation accounts, schedules and keys from a single admin panel.
- **Code examples and no-code integrations:** Ready code samples for Python, Node.js and PHP, plus official integrations for n8n and Make.com automations.
- **Free pack and flexible plans:** Start with a free pack of 50 requests and move to pay-per-request or monthly plans as volume grows.

**Strengths:** Brings Midjourney image generation into your own app without an official API; Cloud option works with no Midjourney subscription and no Discord token; Covers the main Midjourney methods, including Inpaint, Blend and Animate; Code examples for Python, Node.js and PHP plus n8n and Make.com integrations

**Limitations:** It is an unofficial API and is not affiliated with Midjourney, so it depends on platform behavior it does not control; Using your own Midjourney account still requires a Midjourney subscription and a Discord token; Because it relies on Discord accounts, automated usage carries account-risk considerations; Cloud pricing is per image and can add up at high volume

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
