Server-side Web Proof Generation for Twitter API Data

This example demonstrates how to use vlayer Web Proof to notarize an HTTP request to:

https://api.twitter.com/2/users/me?user.fields=id,name,username,created_at,description,profile_image_url,public_metrics

It generates a Zero-Knowledge Proof (ZK proof) based on the API response, which can then be verified by an on-chain EVM smart contract.

How to Run vlayer proving

1. Build Contracts

cd {projectPath}
forge build

2. Install JS Dependencies

cd vlayer
bun install

3. Set Twitter API Bearer Token

Enter your Twitter oauth token to the prove.ts:

const X_API_BEARER_TOKEN = "insert here your oauth2 token";

To get your user OAuth token, you need to create a X/Twitter Developer App and complete the OAuth 2.0 flow.

4. Start Local Devnet

bun run devnet:up

5. Run Proving Process

bun run prove:dev
