1. Agents Buy Insurance
Agents pay a premium (1% of coverage amount) via x402 protocol to insure against API failures and service downtime. Payments are verified on-chain.
2. zkEngine Generates Proofs
When an agent submits a claim, zkEngine analyzes the HTTP response and generates a zero-knowledge proof. The proof cryptographically certifies that failure conditions were met (e.g., status >= 500, empty response) without exposing the actual response dataβlike proving you know a password without revealing the password itself.
3. Automatic USDC Refunds
If the proof verifies, USDC refunds are automatically issued on Base Mainnet. All proofs are publicly auditable.
