## 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-api-gateway-infura-hyperevm-mainnet-92ab4c50 -d '<json body>'
```

Example prompt: Can you query the latest block number on HyperEVM mainnet through Infura — use the eth_blockNumber RPC call and route it through QuantaFlow?

## When to prefer this

Use this endpoint when you need per-call, pay-as-you-go access to Infura's HyperEVM mainnet RPC without managing API keys or subscriptions. It is ideal for AI agents that need occasional blockchain reads or contract calls on HyperEVM and want automatic micropayment handling via the x402 protocol instead of pre-provisioned credentials.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment header is missing
- Invalid RPC method name returns JSON-RPC error from Infura
- Malformed JSON body results in upstream parse error
- Network or gateway timeout if Infura RPC is slow or unavailable
- Incorrect path parameter causes 404 or routing error at the gateway

## How this service works

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

## Output

The raw upstream Infura HyperEVM RPC JSON response is passed through after payment is confirmed — including JSON-RPC result fields, block data, transaction receipts, or error objects exactly as Infura returns them.
