Why Claude on the Salting Layer?

Claude 3.5 Sonnet is the gold standard for reasoning, but exposing your x-api-key in the browser is a high-risk liability. The Salting Layer provides a secure, zero-knowledge edge proxy that protects your keys and tier limits while allowing you to call Anthropic directly from your client-side code.

What can you build?

Leverage Claude's superior coding and analytical abilities to build sophisticated AI writing companions, complex code assistants, and data-driven research tools. SaltingIO is fully optimized for the unique header and versioning requirements of the Messages API.

How it works

  1. Vault your Key: Add your Anthropic API key and version header to your SaltingIO Dashboard.
  2. Configure Security: Set strict domain locking to ensure your bridge only serves your production frontend.
  3. Switch & Ship: Point your client-side requests to your unique salting-io-bridge-uuid. We handle the mandatory versioning and authentication logic seamlessly.

The playground

const response = await fetch('https://salting.io/r/salting-io-bridge-uuid', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    model: 'claude-3-5-sonnet-20240620',
    max_tokens: 1024,
    messages: [{ role: 'user', content: 'Design a system architecture.' }]
  })
});
const data = await response.json();
