How this service works
A paid API for concise, professional agent profile bios. Payment uses USDC on Base through x402.
Output
Returns the USDC balance held by the specified wallet address on the Base network, expressed as a numeric token amount (likely in USDC units or raw wei).
Example use cases
Pre-payment USDC sufficiency check
“Before I send that x402 payment, can you check if wallet 0xAbCd1234... has enough USDC on Base to cover the transaction?”
Portfolio USDC snapshot
“What's the current USDC balance on Base for my wallet 0x9F3a7b2E...? I want to know my stablecoin position right now.”
Agent wallet funding verification
“Check whether the agent wallet at address 0xDeFi5678... has any USDC on Base — I need to confirm it's funded before running the workflow.”
Technical details
Endpoint
GEThttps://signalsprint-mqysbksh.manus.space/service/base-usdc-balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, paid on-chain lookup of USDC balance specifically on the Base network for a given wallet address. Prefer this over building your own RPC call when you want a simple, reliable API abstraction and are already operating within an x402 payment-enabled agent framework.
Side effects
- Invalid or malformed wallet address returns an error
- Address with no USDC holdings returns zero balance
- Network connectivity issues or RPC failures may cause timeouts
- Rate limiting if too many requests are sent in quick succession
- Payment failure (x402) if the $0.005 USDC fee cannot be processed
