Agentic

You can think of Agentic as RapidAPI for LLM tools.

All tools listed on Agentic's marketplace have been carefully hand curated and are regularly tested with a comprehensive set of integration tests and evals. Agentic aims for quality, not quantity.

On the flip side, Agentic makes it easy to publish your own MCP servers & OpenAPI services to Agentic's MCP Gateway and instantly start charging for agentic tool use.

Key features

• Highly Curated Tools: All publicly listed Agentic tools are manually vetted to keep an extremely high quality bar.
• Agentic UX: All Agentic tools have been hand-crafted specifically for LLM tool use. We call this Agentic UX, and it's at the heart of why Agentic tools work better for LLM & MCP use cases than legacy APIs.
• First-Class MCP Support: On both the publishing and consumption sides, Agentic supports MCP as a truly first-class primitive – not an afterthought.
• World-Class TypeScript DX: Agentic is written in TS and strives for a Vercel-like DX, including one-line integrations with every major TS LLM SDK.
• Stripe Billing: Agentic uses Stripe for billing, and most tools are usage-based, so you'll only pay for what you (and your agents) actually use.
• Blazing Fast MCP Gateway: Agentic's MCP gateway is powered by Cloudflare's global edge network. Tools come with customizable caching and rate-limits, so you can REST assured that your agents will always have a fast and reliable experience.
• Semver: All Agentic tools are versioned using semver, so you can choose how to handle breaking changes.
