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 USDC balance (e.g. 150.5 USDC) and the total number of transactions recorded for that agent (e.g. 42 transactions).
Example use cases
Verify agent funds before payment
“Before my orchestrator agent sends payment to the fulfillment agent, can you check if agent ID 'agent_fulfill_99' has enough USDC to cover a $50 transaction?”
Audit agent spending activity
“How many transactions has my trading agent 'agent_trade_7x' made so far, and what's its current USDC balance? I want to see if it's been too active.”
Check wallet before onboarding agent
“I'm about to onboard a new sub-agent with ID 'agent_ops_delta' into my workflow — can you quickly pull its USDC balance and transaction history so I know what I'm working with?”
Technical details
Endpoint
GEThttps://limitguard.ai/v1/wallet/balanceWhen to prefer
Use this endpoint when you need to programmatically check the USDC balance or transaction activity of a specific ERC-8004-compliant AI agent wallet — especially before authorizing inter-agent payments or verifying an agent has sufficient funds. Prefer this over general blockchain explorers when you need structured, agent-identity-aware data in a single fast call.
Side effects
- Unknown or invalid agent_id returns 404 or empty result
- Agent wallet not yet registered on ERC-8004 returns error
- Insufficient payment (x402) blocks the request
- Network or upstream blockchain read errors return 5xx
- Malformed agent_id format returns 400 validation error
