SociaVault is a social media data API that lets developers, marketers, and businesses extract public data from 25+ social platforms — including TikTok, Instagram, YouTube, X (Twitter), LinkedIn, and more — through a single, unified REST API. The Problem We Solve Building social media integrations is painful. Official APIs are restrictive, rate-limited, and require lengthy approval processes. Scraping in-house means maintaining fragile scripts that break every time platforms update. Teams waste months on infrastructure instead of building products. SociaVault eliminates this complexity. One API key. One documentation. Access to every major social platform. How It Works SociaVault provides simple REST endpoints to extract: - Profile data — Follower counts, bios, profile pictures, verification status - Posts and videos — Captions, hashtags, likes, comments, views, shares - Comments and replies — Full comment threads with engagement metrics - Search results — Find users, hashtags, or content by keyword - Trending content — Discover viral posts and emerging creators Data is returned in clean JSON format, ready for your application, dashboard, or analytics pipeline. Key Features No Rate Limits Pull data as fast as you need. Our auto-scaling infrastructure handles the load so you don't have to throttle requests. Real-Time Data Every API call returns fresh data directly from the source. No stale caches or outdated metrics. 25+ Platforms Supported TikTok, Instagram, YouTube, X/Twitter, LinkedIn, Facebook, Pinterest, Threads, Snapchat, Twitch, Reddit, and more — all through one integration. Simple Pricing Pay per successful API call. No monthly minimums, no hidden fees, no enterprise sales calls required. 99.9% Uptime Enterprise-grade reliability with redundant infrastructure and 24/7 monitoring. Who Uses SociaVault? - Marketing agencies tracking campaign performance across platforms - Influencer platforms analyzing creator metrics and audience demographics - Brand intelligence teams monitoring competitors and market trends - Developers building social media tools, dashboards, and integrations - Research teams studying social media trends and engagement patterns Why Teams Choose SociaVault - Access public data without lengthy approval processes or restrictive official APIs - Managed infrastructure that just works — no more broken scrapers after platform updates - One API integration covers 25+ social media platforms - No rate limits or throttling — pull data at the scale you need - Simple pay-per-call pricing with no monthly minimums or hidden fees Security & Compliance SociaVault only accesses publicly available data — the same information visible to any user browsing a profile. We don't access private accounts, direct messages, or data requiring authentication. Our infrastructure is SOC 2 compliant with enterprise-grade security controls. Product Description Company Background SociaVault is built by Ziddec, Inc., a software company focused on making social media data accessible to developers and businesses. Founded in 2024 and headquartered in Delaware, USA, we started as a small team frustrated by the complexity of extracting social media data for our own projects. What began as an internal tool evolved into a full API platform serving hundreds of customers worldwide — from solo developers to enterprise marketing teams. **Average Rating:** 5.0/5.0 **Total Reviews:** 1 #### How Do G2 Users Rate Sociavault? - **Ease of Use:** 8.3/10 (Category avg: 8.8/10) - **Professional Support:** 10.0/10 (Category avg: 9.1/10) #### Who Is the Company Behind Sociavault? - **Seller:** [Ziddec](https://www.g2.com/sellers/ziddec) - **Year Founded:** 2025 - **HQ Location:** Wilmington, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=715386dc3dc6bf8da4f0dc73ee6eb013c860a0bd12f4ecb77c49d84baa75d5e8&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fziddec%2F&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® #### Who Uses This Product? - **Company Size:** 100% Small #### What Are Recent G2 Reviews of Sociavault? **["Great system and interface.

Our platform transforms documents, PDFs, images, scans, emails, spreadsheets, and other unstructured files into structured, schema-validated JSON through a secure, API-first pipeline built for regulated industries. Organizations in financial services, insurance, healthcare, and logistics use Bem when business-critical workflows depend on unstructured data, whether that's processing trust documents, extracting controls from compliance reports, automating claims intake, or digitizing logistics paperwork. Teams define a schema once and reuse it across millions of documents, regardless of layout or format variation. Under the hood, Bem routes each document through the right combination of vision, language, and embedding models, selected automatically from over 18 options. The platform enforces type-safe schema contracts, runs confidence scoring on every extraction, and provides full observability into every processing step. Nothing is a black box: every decision is traceable, every output is auditable. When accuracy matters, Bem's human-in-the-loop review and self-training pipeline means the system improves continuously from corrections made during day-to-day operations. Customers start with a baseline and measurably improve over time, with regression analysis to track the delta. Bem deploys on your terms. Run it as a managed cloud service, connect via private link within your VPC, or deploy on-premises. Multi-cloud and multi-region portability means no vendor lock-in and no data egress when that's a requirement. Compliance, data sovereignty, governance, encryption, and retention policies are built in, not bolted on. Teams get started in minutes through a no-code workflow builder or a full REST API, with no lengthy onboarding or custom implementation required. #### Who Is the Company Behind bem? - **Seller:** [bem](https://www.g2.com/sellers/bem) - **Company Website:** www.bem.ai - **Year Founded:** 2023 - **HQ Location:** San Francisco, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=cf107f8910c011de8d09f791671a4c3c2d9a84726ceaf34fd358187c88130046&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fbem-ai&secure%5Burl_type%5D=linkedin_company_website) 28 employees on LinkedIn® ### [Deck](https://www.g2.com/products/deck/reviews) Deck is the infrastructure layer for accessing user-permissioned data across industries, from utilities and telecom to ERP, ecommerce, and more. **Average Rating:** 5.0/5.0 **Total Reviews:** 1 #### How Do G2 Users Rate Deck? - **Ease of Use:** 10.0/10 (Category avg: 8.8/10) #### Who Is the Company Behind Deck? - **Seller:** [Deck](https://www.g2.com/sellers/deck) - **Year Founded:** 2024 - **HQ Location:** San Francisco, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=b4405b0ebb986603d22c5e9fe191ec48e2578f79e8947c491d4c97043b36084b&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fdeck-platform&secure%5Burl_type%5D=linkedin_company_website) 58 employees on LinkedIn® #### Who Uses This Product? - **Company Size:** 100% Small #### What Are Recent G2 Reviews of Deck? **["Amazing software for connecting to any user-protected page"](https://www.g2.com/survey_responses/deck-review-11284526)** **Rating:** 5.0/5.0 stars _— Sébastien L._ [Read full review](https://www.g2.com/survey_responses/deck-review-11284526) ### [HubRise](https://www.g2.com/products/hubrise/reviews) HubRise is a cloud-based integration platform designed to streamline operations for restaurants, retailers, and software editors.

Konvex is a unified API for ERP integrations that allows B2B SaaS, fintech, and AI companies to connect their product with their customers’ systems through a single integration. Integrating with ERPs like SAP, NetSuite, or Microsoft Dynamics is one of the biggest blockers to selling into mid-market and enterprise. Each integration can take months to build, requires specialized knowledge, and becomes a long-term maintenance burden. Konvex eliminates that complexity. With one integration, you get standardized access to 30+ systems, including SAP Business One, Oracle NetSuite, Microsoft Dynamics, Shopify, and more. We handle authentication, data normalization, infrastructure, and ongoing maintenance, so your team doesn’t have to. Konvex offers two ways to access this infrastructure: - Unified REST API for traditional product integrations - Universal MCP Server for companies building AI agents or running LLMs on top of their customers’ systems This means you can not only integrate data but also enable AI to securely interact with ERP systems through a standardized layer. Instead of building integrations one by one, your product integrates once, and scales across all your customers. What teams achieve with Konvex: - Launch ERP integrations in days instead of months - Close enterprise deals faster - Expand into new markets without rebuilding integrations - Enable AI agents to operate on real customer data (ERP, accounting, eCommerce) - Reduce engineering costs and maintenance overhead Konvex is not an iPaaS or automation tool. It’s integration infrastructure built for companies where integrations are part of the product and increasingly, part of their AI strategy. If your customers require ERP integrations or you’re building AI on top of business data—Konvex becomes your fastest path to deliver both. #### Who Is the Company Behind Konvex? - **Seller:** [Konvex](https://www.g2.com/sellers/konvex) - **HQ Location:** N/A - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=7886df2ed926834e5eb248c77dcfa8e5c815d3ab1f0fe3132ced0dba45868834&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2FNo-Linkedin-Presence-Added-Intentionally-By-DataOps&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® ### [Leen Unified API](https://www.g2.com/products/leen-unified-api/reviews) Leen's Unified API streamlines the integration process by combining multiple APIs into a single, standardized interface. This approach simplifies development by providing consistent access to various services, abstracting away complexity, standardizing interactions, normalizing data formats, centrally handling security, and offering scalability. Developers benefit from maintaining just one integration while accessing centralized documentation and support resources. By leveraging Leen's Unified API, product and security teams can focus on their core roadmaps, rather than getting bogged down with integrations and data pipelines. #### Who Is the Company Behind Leen Unified API? - **Seller:** [Leen](https://www.g2.com/sellers/leen) - **Year Founded:** 2023 - **HQ Location:** San Francisco, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=6260fef065ce860e0d685556356eb5478aadd3adb42cd2fbe8104a49e7551281&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fleen-security%2F&secure%5Burl_type%5D=linkedin_company_website) 14 employees on LinkedIn® ### [Propexo Unified API](https://www.g2.com/products/propexo-unified-api/reviews) The Propexo Unified API is a single property management API for every system your product needs to support. It normalizes data across 10+ property management system (PMS) platforms — including Yardi, RealPage, Entrata, AppFolio, Buildium, MRI Software, ResMan, Rent Manager, Propertyware, and Rentvine, plus rental CRMs like Funnel, Knock, RentCafe, and EliseAI — into one consistent, developer-friendly interface. Building property management integrations the traditional way means learning a different API for every system: separate authentication, separate data models, separate quirks, and constant maintenance as each vendor changes. Proptech teams burn months of engineering on integration plumbing before shipping a single feature. The Propexo Unified API removes that work. Build one integration against one normalized schema and connect to every supported PMS — no per-vendor logic required. Every endpoint returns standardized data models for residents, leases, units, charges, and payments, so a request like GET /v1/residents returns the same structured response regardless of the source system. Read property data and write back where the underlying PMS allows, and use webhooks to receive event-driven notifications the moment data changes across connected systems — no polling required. The Unified API is built for production. It is backed by a 99.9% uptime SLA, enterprise-grade reliability, and 24/7 monitoring, so the integrations you ship stay running. Consistent, predictable endpoints let your team build once and connect everywhere, then scale from a first integration to tens of millions of records without rewriting code. For proptech developers, software vendors, and platform teams serving multifamily real estate, the Propexo Unified API is the fastest path to broad PMS coverage. Ship integrations 10x faster, cut the engineering cost of every new system to near zero, and give your product — and the AI features built on top of it — clean, normalized real estate data to work from. #### Who Is the Company Behind Propexo Unified API? - **Seller:** [Propexo](https://www.g2.com/sellers/propexo) - **Year Founded:** 2022 - **HQ Location:** Boston, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=fd207dbcfb6d84373ccd858680345c4c2eccdbfa3ac1fa3c081c302efcbfac97&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fpropexo&secure%5Burl_type%5D=linkedin_company_website) 2,071 employees on LinkedIn® - [‹ Prev‹ Prev](/categories/unified-apis/free?order=g2_score#product-list) - [1](/categories/unified-apis/free?order=g2_score#product-list) - 2 - [3](/categories/unified-apis/free?order=g2_score&page=3#product-list) - [Next ›Next ›](/categories/unified-apis/free?order=g2_score&page=3#product-list) Spotlight Categories [Corporate Learning Management Systems](https://www.g2.com/categories/corporate-learning-management-systems) [CPQ Software](https://www.g2.com/categories/cpq) [Customer Communications Management Software](https://www.g2.com/categories/customer-communications-management) [Business Process Management Software](https://www.g2.com/categories/business-process-management) [Third Party & Supplier Risk Management Software](https://www.g2.com/categories/third-party-supplier-risk-management) Similar Categories - [Cloud Platform as a Service (PaaS)](/categories/cloud-platform-as-a-service-paas) - [Integrated Development Environments (IDE)](/categories/integrated-development-environments-ide) - [Software Testing](/categories/software-testing) - [Communication Platform as a Service (CPaaS)](/categories/communication-platform-as-a-service-cpaas) - [Help Authoring Tool (HAT)](/categories/help-authoring-tool-hat) - [Other Development](/categories/other-development) - [AI Documentation Generators](/categories/ai-documentation-generators) - [API Development](/categories/api-development) - [API Documentation Management](/categories/api-documentation-management) - [API Generation](/categories/api-generation) - [API Management](/categories/api-management) - [API Marketplace](/categories/api-marketplace) - [API Mocking](/categories/api-mocking) - [API Platforms](/categories/api-platforms) - [Application Development](/categories/application-development) [Browse Unified APIs Themes](/categories/unified-apis/themes)
