How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok'), a data object containing vulnerability findings, and an roi_proof object including a compression_ratio_pct metric. Agents can use the status and data fields to determine whether the checked address exhibits flash loan vulnerability patterns.
Example use cases
DeFi protocol pre-launch security audit
“Before we go live, can you check if our smart contract at 0x4e68Ccd3E89f51C3074ca5072bbAC773960dFa36 has any flash loan vulnerabilities?”
Investigating a suspicious contract
“I found this contract address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on-chain and want to know if it's exploitable via flash loans before I interact with it.”
Routine DeFi security monitoring
“Run a flash loan vulnerability check on 0x3d9819210A31b4961b30EF54bE2aeD79B9c9Cd3B so I can confirm it's still safe after the latest protocol upgrade.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/flashloan-vuln-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.01 USDC) automated check of a smart contract address for flash loan vulnerabilities, especially within an agentic workflow that already settles payments via x402/USDC on Base. Prefer this over manual audits when you need programmatic, machine-readable results for DeFi security pipelines.
Side effects
- Missing or invalid address query parameter returns an error or empty data
- Non-existent or non-contract address may return empty findings
- Payment failure (insufficient USDC on Base) results in 402 response blocking the call
- Malformed request without required 'type' and 'method' fields in input returns validation error
- Network or gateway downtime may return 5xx errors
