How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object with network identifier (eip155:8453), product name, activity object with transfer details, identity and provenance info, and an assessment containing a list of flags, a risk_level string (e.g. 'low'), and a numeric risk_score.
Example use cases
Verify buyer legitimacy before agent purchase
“Before my agent buys that expensive API tool, can you check if the buyer's Base wallet looks legitimate? Pull their recent activity and risk score — I want to make sure they're not flagged before we approve the transaction.”
Monitor wallet safety during marketplace transactions
“We're about to execute a high-value dataset purchase on Base. Can you run a quick preflight check on our wallet address to see if there are any red flags or suspicious transfer patterns that might block the deal?”
Audit vendor wallets for compliance
“I need my agent to evaluate a new vendor's trustworthiness on Base before we work with them. Can you pull their wallet activity from the last 30 days and give me a risk assessment with any concerning flags?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/base/wallet-activity-deltaWhen to prefer
Use this endpoint when you need to monitor recent on-chain transfer activity for a specific Base wallet address combined with an automated risk assessment. Prefer this over generic blockchain explorers when you need machine-readable risk scoring and flags suitable for autonomous agent decision-making, particularly before executing payments or interactions with an unknown wallet.
Side effects
- Invalid wallet address format (not 0x + 40 hex chars) returns validation error
- Invalid or malformed ISO 8601 timestamp returns schema error
- Wallet with no activity since the given timestamp returns empty activity object
- Rate limiting or payment failure returns 402 or 429 error
- Network unavailable returns 5xx error
