## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability httpay-xyz-f6da26ef -d '<json body>'
```

Example prompt: Call eth_getBalance for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet using the Cloudflare RPC gateway.

## When to prefer this

Choose this endpoint when you need Ethereum mainnet JSON-RPC access without managing API keys or subscriptions, prefer micropayment billing per call via x402/USDC, and want Cloudflare's reliable infrastructure. Prefer over Infura or Alchemy gateways on this same host when you specifically want Cloudflare's backend routing. Not suitable for high-throughput batch RPC calls where per-call cost adds up.

## Known failure modes

- Invalid JSON-RPC method returns error code -32601
- Malformed params returns -32602 invalid params error
- Payment not processed (x402 unpaid) returns 402 Payment Required
- Cloudflare RPC backend unavailable returns 502 or 503
- Rate limit exceeded returns 429
- Transaction reverted on-chain returns execution error in result
