How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Alchemy Solana API or JSON-RPC response body is passed through directly after successful x402 micropayment authorization, including blockchain state data, transaction details, account info, or any other Alchemy Solana endpoint response.
Example use cases
Solana wallet balance lookup
“Check the SOL balance of wallet address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM on Solana mainnet using the Alchemy gateway.”
Solana transaction status check
“Look up the confirmation status of Solana transaction signature 5j7s8K... on mainnet — I need to know if it's finalized yet.”
Solana token account query
“Get all SPL token accounts owned by wallet DYw8jCTfwHNRJhhmFcbXvVDTqWMEVFBX6ZKUmygEgZaR on Solana mainnet through the Alchemy API gateway.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-solana-mainnet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use access to Alchemy's Solana mainnet RPC without managing API keys or subscriptions. Ideal for agents that make infrequent or unpredictable Solana RPC calls and want to pay $0.01 USDC per request rather than commit to a plan. Best for web3 agents operating in DeFi or Solana ecosystems that already handle x402 micropayments natively.
Side effects
- Insufficient USDC balance — payment fails and request is rejected with 402 status
- Invalid or malformed path — upstream returns 404 or RPC method not found
- Malformed JSON-RPC body — Alchemy returns error object with code and message
- Solana mainnet node unavailable or degraded — upstream timeout or 503
- Invalid wallet address or transaction signature — Alchemy returns RPC error
- Rate limiting by upstream Alchemy — 429 response passed through
