## 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 quantaflow-x402-gateway-infura-megaeth-mainnet-proxy-272ae8fe -d '<json body>'
```

Example prompt: Query the MegaETH mainnet via Infura — call eth_blockNumber on the /eth/v1 path with a GET and tell me the latest block number.

## When to prefer this

Choose this endpoint when you need pay-per-call access to the Infura MegaETH mainnet RPC without managing an Infura API key subscription, and you are already operating within an x402-capable micropayment environment. It is ideal for low-frequency or bursty blockchain queries where a subscription would be wasteful. Prefer alternatives if you need WebSocket streaming, bulk batch RPC calls, or non-MegaETH chains.

## Known failure modes

- Payment failure: x402 payment of $0.01 USDC not accepted — returns 402 Payment Required
- Invalid path: upstream path not recognized by Infura — returns upstream 4xx error
- Malformed JSON body: invalid JSON forwarded to upstream — returns upstream parse error
- Upstream unavailability: Infura MegaETH node down or rate-limited — returns 503 or upstream error
- Unsupported method: HTTP method not accepted by upstream path — returns 405

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream response body from the Infura MegaETH mainnet node, passed through with its original content type after successful x402 micropayment settlement. Typical payloads are JSON-RPC response objects containing blockchain data such as block info, balances, transaction receipts, or contract call results.
