Warm greetings! I’m an expert in API integration and software architecture, with 9+ years of experience working with third-party APIs and SaaS platforms. I understand you are specifically looking for an existing, working plagiarism/AI-detection API service—not an API built from scratch. Here’s how I can help: * Identify and integrate a legitimate existing Turnitin/iThenticate-compatible API service * Handle file submission, similarity results, AI detection, and report retrieval * Configure PDF reports/report links and no-repository checking where supported * Review API documentation, limits, credits, and commercial integration terms * Support scalable integration for ongoing and higher-volume usage Before proceeding, I’d like to confirm the exact supplier/API access you already have or expect us to source, as commercial third-party integration and redistribution rights are critical here. If you have an existing API provider or documentation, please share the details so we can verify compatibility and pricing.

Hi there, Your academic platform needs a stable, already-operational Turnitin or iThenticate-compatible service, not a newly developed API, with file submission, result retrieval, similarity reports, and optional AI detection. I have strong hands-on experience with API Development and Software Architecture and have solved similar problems involving third-party service integration, document-processing workflows, and reliable result polling. My approach would be to: * Review the existing integration requirements, API documentation, service limits, and current platform architecture. * Identify the root cause of any integration risks and determine what can be reused versus what needs to be changed. * Implement a clean, maintainable solution using secure API authentication, asynchronous submission, status tracking, and report retrieval. * Test edge cases, reliability, performance, security, and integration behavior. * Deploy or integrate the service without disrupting the existing system. A production integration should account for asynchronous processing, cooldowns, rate limits, report availability, and commercial third-party usage rights before higher-volume adoption. I prefer fixing the actual root cause rather than applying temporary patches, and I will keep the implementation simple, stable, and maintainable. I can start by reviewing the available API documentation, test access, report formats, pricing model, and current setup, then proceed with the most practical solu

Hi, I am an API integration specialist with 8 years of experience connecting third-party services to academic and SaaS platforms. I can help evaluate and integrate an existing licensed Turnitin or iThenticate-compatible service for file submission, similarity results, AI detection where available, and PDF reports or report links. I can review API limits, pricing, commercial-use permissions, repository settings, bulk plans, and data-handling requirements before integration. I do not want to misrepresent this as a new API development project, so I would first confirm the available provider and test access, then connect the approved service reliably to your platform for long-term use. I'm an individual freelancer and can work in any time zone you prefer. Please contact me with the best time for a quick chat. I look forward to discussing more details. Thanks, Emile

Hi, I can help integrate an existing, properly licensed plagiarism/AI detection API into your academic platform, with a focus on reliable file submission, result retrieval, report handling, and long-term API stability. I’d also verify that commercial third-party integration and your intended usage model are explicitly permitted by the provider before implementation. The integration can be structured around PDF/file upload, similarity results, AI detection where supported, report links or PDFs, error handling, usage limits, and monitoring. I can also help evaluate providers based on per-check pricing, volume discounts, API limits, documentation, and scalability. I have strong experience with API integrations, backend architecture, automation, and third-party services. My previous work is here: https://www.freelancer.com/u/jorginhoo1 Happy to discuss your expected volume and help determine the right compliant service for a long-term integration. Best regards!

As an experienced developer with a vast skill set and a strong understanding of API development, I understand the unique needs of your project. Although this particular project is not about API development itself, my skills in this area are paramount in ensuring smooth integration of the existing Turnitin/iThenticate API into your academic platform. Over the past 8 years, I have had multiple opportunities to work on various projects involving complex tasks such as developing APIs for client-server communications, creating APIs for data exchange and also integrations with third-party applications. This has endowed me with the ability to seamlessly navigate through such API installations. Additionally, in recent years, I've notably dabbled in cloud services which I feel will especially come in handy while working on your project; specifically, AWS (EC2, Amplify, S3) which actively supports Turnitin. My well-rounded technical skillset also includes competencies in HTML, CSS, JavaScript, Node.js and more. In terms of reporting features you seek like similarity/plagiarism checking and AI detection - these align perfectly with my prior experience as well. Furthermore, you can count on me to provide excellent service quality throughout our long-term professional relationship. Let's connect to discuss the pricing model per check or credit; daily limits and cooldowns, and any other details that may be essential for our collaboration.

Hi, You're seeking a ready-made Turnitin/iThenticate API service with stable, long-term access. The root causes are licensing constraints and limited suppliers offering production-grade, long-term API access. Solution: I verify an existing API partner, secure sandbox/test access, and implement file submission, result retrieval, and PDF/report delivery with optional AI detection if available. I ensure no repository checks and define clear daily limits with scalable pricing. Experience: I recently integrated Turnitin/iThenticate-based workflows for a 20k-student platform, delivering automated reports via PDF and a reliable API with test access. In another project, I set up reseller-friendly SLA and high-volume throughput with stable uptime. Smart improvement: propose a staged onboarding with a pilot of 1k checks to validate latency, pricing, and integration before full rollout. Question: Do you have a preferred SLA, data residency, or regional constraint for long-term usage? Thank you, - Bohdan

I understand you're seeking a direct integration with Turnitin or iThenticate's existing API for your academic platform, specifically avoiding any development work on your end. My expertise lies precisely in establishing and managing these types of integrations for platforms requiring robust plagiarism and AI detection capabilities, ensuring seamless data exchange and report retrieval. My approach involves leveraging established API connectors and robust error handling protocols to integrate your platform with the Turnitin/iThenticate service. I will handle all authentication, submission of documents (likely via PDF upload), and retrieval of similarity scores and AI detection results. The process will be streamlined to deliver a report link or PDF directly to your system, respecting the "No Repository" checking requirement. To ensure a perfect fit, could you clarify the expected volume of submissions per day/week? Also, are there any specific reporting formats or data points you require beyond a general similarity score and AI detection result? I'm available for a brief call to discuss how we can rapidly implement this critical functionality.

Before providing an accurate timeline, scope, and budget, I’d like to clarify a few key details to ensure we're aligned from the start. Freelancer’s proposal character limit makes it difficult to cover everything thoroughly here. If you're available, let's connect via chat.

Once I understand your expectations, I'll provide a clear execution plan with realistic timelines and pricing. I’m ready to get started as soon as we finalize the details and look forward to working with you. Best regards, Mayank Sahu

Hi, I have developed several projects of this kind, and at their core they involve integrating existing third-party API services into platforms, handling authentication, submissions and result retrieval reliably. ? The most important and difficult part is finding an existing working service that allows commercial third-party integration and then keeping it stable for long-term, regular usage. ✅ When I developed this kind of project, I actually faced API access being restricted to direct institutional customers rather than resellers, rate limits and cooldowns affecting volume, and commercial use terms that blocked platform integration. I solved this by working only with providers who explicitly permit third-party integration, confirming the allowed use case and volume upfront, and building proper retry and rate-limit handling so the service stayed reliable under regular load. ✅ The result is that integrations ran stably with clear volume expectations and the platform could scale usage without breaking service terms. I can contribute to implement your idea with this kind of experience. Looking forward to discussing with you about your vision. Best regards, Michel

The real challenge here isn’t the plagiarism check itself—it’s finding an existing Turnitin/iThenticate-based service that can actually survive long-term platform use, higher volume, and commercial third-party integration** without repository checking or unreliable result retrieval. Your requirements point to a supplier that already has the infrastructure in place: file submission → similarity/AI results → PDF report or report link, backed by clear API documentation, stable limits, and pricing that still makes sense as usage grows. I’d focus the discussion around exactly those points rather than proposing unnecessary API development. The commercial integration permission is especially important to verify upfront so there are no issues once the platform starts scaling. Before proceeding, does the service need to be officially authorized for resale/third-party commercial integration, or are you open to any existing API provider that permits this use under its terms?..

Hi, I understand that you are looking for an existing Turnitin/iThenticate API-based service for integration into your academic platform, rather than custom API development. I have experience integrating third-party APIs and plagiarism-detection workflows into web platforms and can assist with evaluating API capabilities, integration architecture, report handling, file submission workflows, result retrieval, authentication, and scalability requirements. To determine the best approach, I would need details about the specific API/service provider, available documentation, report formats, rate limits, pricing structure, and commercial usage permissions. Once reviewed, I can provide a clear integration plan, timeline, and cost estimate for incorporating the service into your platform. I would be happy to discuss the requirements further and review any available API documentation or demo access.

An existing plagiarism API needs proven access, stable usage, and clear commercial terms. Hi, I can provide an existing, working Turnitin/iThenticate API-based service for direct integration rather than developing an API from scratch. The setup can support file submission, similarity checking, result retrieval, and PDF report/report-link delivery, with AI detection where available and no Repository checking. For the partnership, I can provide the relevant API documentation, test access, usage limits, pricing per check/credit, and available bulk or reseller options. Commercial third-party integration terms will also be clearly confirmed before integration. I understand this is intended as a long-term service with potentially increasing volume, so stability, predictable limits, and scalable pricing will be important from the start. Regards, Hamza

You need a verified, production-ready plagiarism and AI-content detection API you can wire directly into your academic platform without building anything from scratch, and you want a supplier relationship that scales reliably over time. I operate an established API-based detection service built on iThenticate infrastructure. Here is what I can confirm upfront: similarity checking against web and publication databases, AI-generated content flagging, no student repository submission, PDF report delivery plus shareable result links, and full REST API documentation with sandbox credentials available before any commitment. On your specific questions: pricing runs per-check with tiered reseller rates that drop meaningfully at volume thresholds we can define together. Daily throughput limits are generous for typical academic platform loads, and I can detail exact cooldown windows on a call. Commercial third-party integration is explicitly permitted under the arrangement I hold. My integration concern for you is latency on async result retrieval, which I handle with webhook callbacks rather than polling, keeping your platform responsive. I can turn around test credentials within 48 hours of a brief alignment call. Can we schedule 20 minutes this week so I can confirm your expected monthly volume and match you to the right pricing tier?

The KEY point of this project is not building an API, but providing an existing, stable Turnitin/iThenticate-based service that can support commercial third-party integration long term. The main blocker is licensing and service reliability: API access must legally allow external platform integration, while supporting predictable limits, reports, and volume growth. My approach is straightforward: • Existing working API/service with file submission and result retrieval. • Similarity reports, No Repository mode, and AI detection where available. • API documentation and test access before integration. • Clear per-check pricing, daily limits, and bulk/reseller terms. • Stable endpoint and report delivery for long-term usage. Once the exact service terms are confirmed, I can provide the pricing, limits, demo access, and commercial-use conditions clearly. I wish we could discuss more details. Best regards, Rex
