Cryptographically verifiable AI inference
18 zkML features from real Uniswap V2 contracts
Cryptographic proof of correct AI execution
âšī¸ This cryptographic proof guarantees that the AI model ran correctly on the input features. The proof was generated using Jolt-Atlas zkML and verified locally before being returned.

đ Demo Mode (Free Testing):
âĸ Use payment_id starting with "demo_" (e.g., demo_test_123)
âĸ No payment required - instant testing!
đ° Production Mode:
1. Send 0.1 USDC to the service wallet on Base network
2. Use the transaction hash as payment_id
3. Call the API with your contract address
RugDetector is fully x402-compliant, enabling native HTTP payment flow using industry-standard headers.
When payment is required, the API returns:
HTTP/1.1 402 Payment Required
X-PAYMENT-RESPONSE: eyJzY2hlbWVzIjpbeyJzY2hlbWUiOi...
WWW-Authenticate: x402

}Include payment proof via X-PAYMENT header (base64-encoded JSON):
// Payment payload (before encoding)

}

-H "X-PAYMENT: eyJzY2hlbWUiOiJleGFjdCIsIm5ldHdvcmsi..." \
-d '{"contract_address": "0x1234..."}'The X-PAYMENT-RESPONSE header contains base64-encoded payment details:
// Decoded X-PAYMENT-RESPONSE header

}âšī¸ Dual Payment Support: RugDetector accepts payment proof via both X-PAYMENT header (x402 standard) and JSON body payment_id field for maximum compatibility.
