## reAPI

Most teams building with generative AI end up integrating the same capability several times over: one client for chat, another for images, another for video, each with its own authentication scheme, retry semantics, rate-limit behaviour and billing relationship. reAPI's proposition is that these should collapse into one integration. Your existing OpenAI-style client library keeps working; you change the model name in the request to route to a different vendor, and reAPI handles vendor selection, failover and routing behind the curtain.

The models on offer span image generation (GPT Image, Nano Banana, Seedream, FLUX, Midjourney), video (Seedance, Veo, Kling, Vidu, MiniMax, Grok Imagine), language models (Claude, Gemini, GPT, DeepSeek, GLM, Kimi), music and audio tools (Suno, Mureka, vocal and stem utilities) and a set of text utilities such as humanising and AI-text detection. reAPI states its rates are below the vendors' published list prices — for example it lists GPT Image 2 1K at $0.004 per image against an official $0.219 — although any individual figure should be checked on their live page before you plan a budget around it.

Operationally, the platform markets 99.96% uptime with sub-second failover: if one upstream provider degrades, the request is re-routed to a redundant vendor rather than failing. Requests and responses are not stored on reAPI's side. Spending is controlled through prepaid credits (1 credit = $0.001) with per-key spend caps and team budget controls, plus region pinning to route traffic through EU, US or APAC data regions. Failed generations are refunded automatically. There is a playground for testing models before wiring them into production, plus documentation, guides and an MCP server for AI agents.

**Pricing & Plans:** Paid, credit-based, pay-as-you-go. You top up a prepaid balance where 1 credit equals $0.001 and pay only for calls you make — only completed generations are billed, and failed ones are refunded. Model rates are listed per call, per second or per 1M tokens depending on the model. Per-key spend caps and team budgets are available for cost control.

- **One unified endpoint:** Reach image, video, chat, music and code models from many vendors through a single API key and an OpenAI-compatible request shape, so existing client code keeps working.
- **Automatic failover and routing:** reAPI handles vendor selection and re-routes requests to a redundant provider when one degrades, which the company positions as sub-second failover behind a 99.96% uptime claim.
- **Zero request logging:** The platform states that your requests and responses are never stored on its side, which matters for teams with data-handling obligations.
- **Credit-based spend control:** Billing runs on prepaid credits worth $0.001 each, with per-key spend caps, team budget controls and automatic refunds for failed generations.
- **Region pinning:** Route traffic through EU, US or APAC data regions to align with latency targets and data residency requirements.
- **Playground, docs and MCP server:** Test models in a browser playground, read model-specific docs and pricing, and connect agents through a provided MCP server.

**Strengths:** A single OpenAI-compatible integration covers image, video, language, music and code models; Automatic failover and redundant routing reduce the blast radius of any one provider going down; Credit-based prepaid billing with per-key caps makes spend predictable and auditable; Stated rates sit below vendors' published list prices, with failed generations refunded

**Limitations:** You are trusting a middle layer between your application and the underlying model vendors; Published figures move quickly as new models launch, so pricing must be re-checked before committing to a budget; Costs are quoted per image, per second or per million tokens depending on the model, which takes effort to forecast accurately

## 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
