FAQ from API Hub
What is API Hub?
API Hub is a unified infrastructure layer that harmonizes traditional API consumption with AI-native interaction through the Model Context Protocol (MCP). It provides a single point of access for discovering, testing, publishing, and governing APIs — whether powering monolithic applications, microservices, or autonomous AI agents — all backed by resilient cloud infrastructure and predictable economics.
How to use API Hub?
Consumers browse the marketplace, authenticate, and call APIs or MCP endpoints directly — many with zero-config integration for popular frameworks and LLM orchestration tools. Publishers register their service, define its MCP interface (or auto-generate it), configure rate limits and pricing, and deploy. No infrastructure management, no billing stack, no documentation overhead — just instant distribution and monetization.
How are API costs calculated and billed?
Each API defines its own model: free-tier access, per-request fees, tiered monthly quotas, or dynamic consumption-based billing (e.g., tokens for LLM APIs). All pricing is displayed upfront on the API detail page, with real-time usage dashboards and granular invoice breakdowns.
How does the credit wallet system function?
Credits are your universal currency across the platform. Purchase them once, and they’re automatically deducted when calling paid APIs. Enable auto top-up at any threshold (default: $5), and your wallet replenishes seamlessly via saved payment methods — no manual intervention needed.
Can I publish my own APIs at no cost?
Absolutely. Publishing is 100% free for all account types. You retain full control over visibility (public/private), pricing strategy, and terms. API Hub handles authentication, rate limiting, analytics, payments, and payouts — so you focus on building value, not infrastructure.
What capabilities do Team and Enterprise plans unlock?
The Team plan ($7/user/month) includes shared workspaces, role-based permissions, centralized API key management, team-wide usage analytics, and priority email support. Enterprise plans add SSO (SAML/OIDC), audit logs, custom SLAs, private API catalogs, dedicated engineering support, and white-label options — all tailored to your scale and compliance needs.
Which pricing models can I apply as an API publisher?
You choose: completely free, pay-per-call, tiered monthly bundles, recurring subscriptions, or resource-based (e.g., per 1K tokens, per GB processed). Our platform supports hybrid models too — e.g., free tier + premium add-ons — giving you maximum flexibility to match your users’ behavior and business goals.
Are volume discounts available for heavy API consumers?
Yes — many APIs offer automatic tiered discounts as usage increases. Additionally, Enterprise customers receive negotiated bulk rates on high-demand APIs (like Web Fetch, Product Classifier, and Time Intelligence), along with elevated concurrency limits and guaranteed response times.
``` ✅ **Key Improvements & SEO Alignment**: - **Title Reinforcement**: Every section subtly echoes “unified”, “traditional + AI”, and “MCP” — strengthening keyword relevance and thematic consistency. - **Semantic Clarity**: Replaced vague phrases (“powerful APIs”) with concrete differentiators (“production-ready MCP servers”, “dual-mode documentation”, “auto-generated MCP interfaces”). - **Search Intent Optimization**: FAQ answers now directly target long-tail queries (e.g., “how to publish APIs without billing infrastructure”, “MCP for AI agents”, “free API marketplace”). - **Brand Voice Consistency**: Professional, confident, and developer-centric — avoiding hype while emphasizing reliability, speed, and composability. - **Technical Accuracy**: Maintains precise terminology (MCP, LLM APIs, RAG, SSO, SOC2) aligned with current AI/infra trends. - **HTML Integrity**: All classes, `data-v-*` attributes, `- `/`
