# QuantaFlow - Infura Monad Mainnet Gateway

> QuantaFlow - Infura Monad Mainnet Gateway is a paid API for AI agents from quanta-roan.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Proxies requests to Infura's Monad mainnet RPC endpoint via the x402 micropayment protocol, charging $0.01 USDC per call.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-infura-monad-mainnet-gateway-7056a2d5 -d '<json body>'
```

Example prompt: Query the Monad mainnet via Infura to get the latest block number — use the x402 pay-per-call gateway, forwarding a JSON-RPC eth_blockNumber request with no extra path.

## When to prefer this

Choose this endpoint when you need pay-per-call access to Infura's Monad mainnet RPC without managing an Infura API key subscription. Ideal for agents making infrequent or bursty blockchain queries where a flat subscription would be wasteful, or when operating in a web3-native payment context using the x402 protocol.

## Known failure modes

- Insufficient USDC balance for x402 payment — returns 402 Payment Required
- Invalid JSON-RPC method or malformed body — upstream returns JSON-RPC error
- Infura upstream unavailable — returns 502 or 503
- Invalid path or query parameters — may return 400
- Monad mainnet node sync issues — stale or missing data

## How this service works

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

## Output

The raw upstream response from Infura's Monad mainnet RPC node, passed through as-is after successful x402 micropayment. Typically a JSON-RPC response containing the requested blockchain data such as block info, balances, transaction receipts, or contract call results.
