Overview
WorkProof provides cryptographically verifiable proof that AI agents have executed code correctly. Every verification runs in an isolated Fly Machine with results attested on Base Sepolia.
Network
Currently live on Base Sepolia testnet. Mainnet deployment planned for Q2 2025.
What is WorkProof?
AI agents are increasingly performing critical tasks—trading, data analysis, code generation. But how do you know the agent actually did the work correctly?
WorkProof solves this by:
- Isolated Execution — Each verification runs in a fresh, sandboxed VM with no network access
- Cryptographic Verification — Output hashes are compared against expected values
- On-Chain Attestation — Every successful verification is recorded on Base Sepolia
- x402 Payments — Pay per use, no subscriptions or API keys

Quick Start
1. Send Payment
Send 0.001 ETH on Base Sepolia to:
Payment Address
0x75E95F6Dfb96d1aF22E2eEaAb3044cDa42b88562
2. Submit Verification
Use the transaction hash as your payment header:
Request
curl
curl -X POST https://api.workproof.run/verify \
-H "Content-Type: application/json" \
-H "X-402-Payment: 0x..." \
-d '{
"taskType": "code-execution",
"code": "console.log(2+2)",
"expectedHash": "8e9075af..."
}'
3. Receive Result
Response
json
{
"jobId": "a125a3a5...",
"status": "completed",
"result": "VALID",
"registryTxHash": "0x7566...",
"executionTimeMs": 2066
}
