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 and content-type from Alchemy's Plasma mainnet are passed through unchanged after the $0.01 USDC x402 payment is settled. The agent receives exactly what Alchemy would have returned directly.
Example use cases
Fetch latest Plasma mainnet block
“Get me the latest block number from Alchemy Plasma mainnet — send a JSON-RPC call to /v2 with method eth_blockNumber and an empty params array.”
Check wallet balance on Plasma
“Look up the ETH balance for wallet address 0xAbC123... on Alchemy Plasma mainnet by calling /v2 with eth_getBalance and block tag 'latest'.”
Retrieve transaction receipt on-chain
“Pull the transaction receipt for tx hash 0xDef456... from Alchemy Plasma mainnet using eth_getTransactionReceipt forwarded through QuantaFlow.”

Choose this endpoint when you need pay-per-use, subscription-free access to Alchemy's Plasma mainnet RPC without managing API keys or monthly plans. It is ideal for agents that make infrequent or unpredictable on-chain queries and want to pay only for what they use via USDC micropayments on the x402 protocol.
Side effects
- Payment failure: insufficient USDC balance or x402 facilitator rejection returns a 402 Payment Required error
- Invalid path: malformed or unsupported Alchemy endpoint path returns an upstream 404 or error JSON
- Bad request body: malformed JSON in the body field causes an upstream 400 error
- Rate limiting: upstream Alchemy rate limits may return 429 Too Many Requests
- Network error: Vercel or upstream Alchemy unavailability returns 5xx errors
