How this service works
ERC-8004 agent wallet balance check. Returns USDC balance and transaction count for AI agent wallets.
Output
Returns a JSON object containing the agent wallet's current USDC balance (e.g. 150.5 USDC) and the total number of transactions the wallet has made (e.g. 42).
Example use cases
Verify agent has funds before delegation
“Before I assign this data processing task to agent-0x7f2e9d, can you check if it has enough USDC in its wallet and how active it's been?”
Monitor autonomous agent spending patterns
“I need to keep tabs on our fleet of agents. Can you pull the USDC balance and transaction history for agent-0xf4c2a8 so I can see if it's spending within expected parameters?”
Validate agent trustworthiness for payment
“We're about to send a significant amount of USDC to agent-0x9b1e5c for a market making task. Can you quickly check its wallet balance and how many transactions it's completed so far?”

Endpoint
GEThttps://api.limitguard.ai/v1/wallet/balanceWhen to prefer
Use this endpoint when you need to quickly check an AI agent wallet's USDC balance and transaction history count before authorizing inter-agent payments, delegating tasks, or assessing agent financial activity. Prefer this over full compliance or trust-score endpoints when only balance/transaction data is needed and you want a lightweight, low-cost check.

- Agent wallet not yet registered in ERC-8004 registry returns not-found error
