```

Example prompt: What's the total USDC balance for Solana wallet HD1ryR3dYSXBVNGfJZydbpmnChiE1wrAQkupWWtHt4pM? I want to make sure it has enough to cover the payment before I proceed.

## When to prefer this

Use this endpoint when you need a quick, single-call lookup of a Solana wallet's total USDC balance — especially before initiating or accepting a USDC payment on Solana. Prefer this over general Solana RPC calls when you want a clean, aggregated balance that sums across all USDC token accounts without writing custom logic.

## Known failure modes

- Invalid or malformed base58 wallet address returns an error
- Wallet address with no USDC token accounts returns zero balance
- Network or RPC node timeouts may cause failed lookups
- Missing required 'address' query parameter returns a validation error
- Rate limiting or payment failure if x402 payment not included

## How this service works

Coinlight charges USDC per API call with the x402 protocol on Solana and Base.

## Output

A JSON response containing the total USDC balance (summed across all USDC token accounts) for the specified Solana wallet address, labeled under the endpoint name.
