When to prefer

Choose this endpoint when you need quick, actionable Solidity gas optimization advice without setting up API keys or subscriptions. Ideal for developer tools, coding assistants, or smart contract auditing workflows that want to surface gas-saving patterns on demand. At $0.005 per call with no onboarding friction, it suits low-volume, ad-hoc developer tooling.

Side effects

402 Payment Required if USDC payment via x402 is not attached or insufficient
Network errors reaching httpay.xyz
Occasionally generic or repeated tips due to random selection
No input validation needed but payment must be on Base network

Input

{
  "query": "ethereum gas prices"
}

Output

{
  "tip": "Use `bytes32` instead of `string` when possible. Fixed-size is cheaper than dynamic.",
  "meta": {
    "x402": true,
    "poweredBy": "Alfred Zhang 🫡"
  },
  "source": "Battle-tested optimization patterns",
  "gasSaved": "~3587 gas per call"
}
