Example prompt: Can you check the ETH balance of wallet address 0xAbC123... on Ethereum mainnet using JarvisClaw's pay-per-call RPC gateway?

## When to prefer this

Choose this endpoint when you need metered, pay-per-call Ethereum RPC access without committing to a subscription, especially in agentic workflows where usage is unpredictable. Prefer it when you want crypto-native micropayment billing settled in USDC rather than API key management. The UAT URL suggests this is a staging/testing environment — use for development and evaluation before relying on production.

## Known failure modes

- Invalid RPC method name returns JSON-RPC error with code -32601
- Malformed query parameter returns 400 Bad Request
- Insufficient x402 payment or missing payment header returns 402 Payment Required
- UAT environment may have reduced reliability or rate limits compared to production
- Contract call to non-existent address returns empty result or error
