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 Alchemy's Berachain mainnet API is passed through as-is, preserving the original response body and content type (typically JSON-RPC results, block data, transaction receipts, or contract call results).
Example use cases
Fetch Berachain wallet token balances
“Look up the current token balances for wallet address 0xABC123 on Berachain mainnet using Alchemy — I need all ERC-20 holdings.”
Read smart contract state on Berachain
“Call the read-only balanceOf function on the Berachain mainnet contract at 0xDEF456 for address 0x789ABC — use the Alchemy RPC and pay per call.”
Retrieve recent Berachain transaction details
“Fetch the full details of transaction hash 0xTXHASH123 on Berachain mainnet via Alchemy so I can verify it confirmed.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-berachain-mainnetWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's Berachain mainnet RPC without committing to a subscription, especially in agent workflows that make infrequent or unpredictable numbers of blockchain queries. Ideal for agents that need to read on-chain data, call smart contracts, or inspect transactions on Berachain without managing API keys — payment is handled automatically via x402 USDC micropayments.
Side effects
- Payment failure – insufficient USDC balance causes 402 rejection before request is forwarded
- Invalid path – malformed or unsupported Alchemy API path returns upstream 404 or error
- Malformed JSON body – invalid JSON in body field causes upstream parse error
- Alchemy rate limit or outage – upstream 429 or 5xx passed through from Alchemy
- Network timeout – Berachain mainnet node latency causes gateway timeout
