API Secure is the fastest way to share API keys with AI agents — no servers, no accounts, no tracking. Your key is encrypted with AES-256-GCM directly in your browser and never touches a server. The AI agent decrypts locally, completing a zero-knowledge credential handoff in seconds. Purpose-built for developers working with AI agents, it eliminates the friction of password managers and CLI tools for one-off key sharing. Open source, fully auditable, and free forever.see more

About

Managing sensitive API keys when integrating them with new AI agents or third-party services can often feel like a risky balancing act. You need speed and convenience, but you absolutely cannot compromise on security. That is precisely why we built API Secure. This isn't just another credential sharing tool; it’s a fundamentally different approach designed specifically for the modern developer working at the intersection of code and artificial intelligence. Imagine needing to grant an AI agent access to a specific service endpoint for a quick test or a temporary task. Instead of digging through complex password managers, setting up temporary access tokens that expire awkwardly, or worse, pasting credentials into an insecure chat window, API Secure offers an instant, ironclad solution. Your API key is encrypted right there in your browser using robust AES-256-GCM encryption before it ever leaves your machine. This means the key is scrambled and protected before it even hits the network, ensuring that no intermediary, including our own systems, ever sees the raw secret. It’s a zero-knowledge handoff built for speed and absolute privacy.

What truly sets API Secure apart is its commitment to simplicity and trust. There are no servers involved in the actual key transfer process, which eliminates an entire class of potential vulnerabilities. Once you generate the secure link, the receiving AI agent—or any other authorized party—decrypts the key locally on their end. This seamless, serverless architecture drastically reduces friction, making those one-off key sharing scenarios painless and instantaneous, something traditional developer tools often complicate. We understand that developers value transparency, which is why API Secure is fully open source. You can audit every line of code to verify exactly how your data is being handled, giving you complete peace of mind that your most valuable secrets remain yours. It’s designed to be the fastest, most secure, and most auditable way to bridge the gap between your applications and the powerful new world of AI agents, removing the typical security overhead so you can focus purely on building and iterating.

This tool is purpose-built for developers who are tired of clunky workflows and unnecessary security risks when collaborating or testing integrations. Whether you are quickly onboarding a new automation script or sharing temporary access with a colleague for debugging, API Secure provides an elegant, modern solution that respects your security posture without slowing down your development cycle. It’s free forever, requires no accounts or signups, and operates with a level of security that should be standard for handling sensitive credentials in the AI era. Stop worrying about where your keys are going and start integrating faster with confidence.
