Example prompt: Can you check the token balance for wallet address 0xAbC...123 on the Base network using Crypto Shark?

## When to prefer this

Choose this endpoint when you need a low-cost, pay-per-call on-chain token balance lookup on supported networks (especially Base) without needing to run your own node or pay for a premium RPC subscription. Ideal for autonomous agents that need occasional balance checks at $0.001 per call via x402 micropayments.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported network identifier causes a rejection
- Contract address not found on the specified network
- Rate limiting or payment failure via x402 if USDC balance is insufficient
- Stale or delayed data if the chain is experiencing congestion

## How this service works

Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents

## Output
