# QuantaFlow x402 Gateway – Infura Solana Mainnet

> QuantaFlow x402 Gateway – Infura Solana Mainnet is a paid API for AI agents from quanta-roan.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Proxies POST requests to Infura's Solana mainnet RPC endpoint, billing $0.01 USDC per call via the x402 micropayment protocol

## 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-solana-mainnet-0e5e705e -d '<json body>'
```

Example prompt: Can you query the Solana mainnet via Infura to get the current SOL balance for wallet address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM using the getBalance RPC method?

## When to prefer this

Use this endpoint when you need pay-per-call access to Infura's Solana mainnet RPC without a subscription or API key, leveraging x402 micropayments ($0.01 USDC/call). Ideal for agents that need occasional or burst Solana RPC access without committing to a plan, or for web3 applications that want programmable, wallet-funded blockchain queries.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
- Invalid RPC path or method: Infura returns a JSON-RPC error with code and message
- Malformed JSON body: upstream parse error returned in response
- Solana mainnet unavailability: upstream 5xx error passed through
- Rate limiting by Infura: 429 Too Many Requests forwarded from upstream

## How this service works

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

## Output

The raw upstream Infura Solana mainnet RPC response body, passed through transparently after successful x402 payment — typically a JSON-RPC result containing the requested blockchain data (balances, transaction details, block info, account state, etc.)
