How this service works
Run a transaction simulation and EVM safety preflight with gas, destination proxy evidence, and optional token security and allowance checks in one decision-ready report.
Output
Returns a JSON object with a boolean success flag, a safety decision string (e.g. 'no_obvious_issue_detected'), a broadcast recommendation flag, and the count of security checks completed against the transaction.
Example use cases
Token approval safety screen
“I'm about to approve a new DeFi protocol at 0x1234abcd... to spend my USDC token at 0xA0b86991... on Base — can you run a preflight security check to see if the spender contract looks safe before I sign?”
Suspicious calldata detection
“Someone sent me a transaction to sign: destination 0xDeadBeef... on Ethereum, calldata 0x23b872dd... — can you simulate it and check if there's anything malicious going on before I approve it?”
Pre-broadcast DeFi trade validation
“I want to swap tokens on a new DEX at 0x9876fedc... on Arbitrum — the calldata is 0x38ed1739... and I'm sending from 0xMyWallet... — please preflight check this and tell me if the security checks pass before I broadcast.”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/transaction_preflightWhen to prefer
Use this endpoint when an AI agent needs to screen an EVM transaction for security risks before signing or broadcasting — especially useful for token approvals, DeFi interactions, and interactions with unknown contracts. Prefer over manual review when operating autonomously on behalf of users on Base, Ethereum, or Arbitrum, and when a lightweight per-call USDC fee ($0.012) is acceptable in exchange for automated multi-source security evidence.
Side effects
- Invalid or malformed hex calldata returns an error
- Unsupported chain identifier causes rejection
- Unresolvable contract address yields incomplete evidence
- GoPlus security service unavailability may reduce checks_completed count
- Missing required 'to' field causes validation failure
