zkFetch

fetch, but with a zkproof

zkFetch allows you to securely fetch remote resources over HTTPS endpoints, providing a proof of correct execution that can be verified by third parties. This ensures that sensitive operations, such as using private API keys, are performed correctly without exposing confidential information.

Overview

You can integrate Reclaim into your backend using zkFetch SDK

Flows

Integrating zkFetch

The workflow is as follows:

1. Initiate Request: The user calls zkFetch, providing options such as URL, method, and headers.
2. Fetch and Generate Proof: zkFetch performs the fetch operation and generates a proof
3. Verify and Transform Proof: The proof is verified using verifySignedProof and transformed with the transform method

When to Use zkFetch

zkFetch is recommended for fetching public data where the integrity and authenticity of the data need to be verified without exposing any sensitive information. Use zkFetch in scenarios such as:

• Ideal when data is publicly available
• Perfect when you have the auth token and endpoint
