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 from Alchemy's Abstract mainnet node is passed through directly, including JSON-RPC results such as account balances, block data, transaction receipts, or contract call outputs, along with the appropriate content-type header.
Example use cases
Check wallet balance on Abstract mainnet
“Look up the ETH balance of wallet address 0x1234...abcd on the Abstract mainnet using Alchemy — pay the per-call fee and return the balance.”
Fetch latest block data for DeFi app
“Grab the latest block number and its transaction count from Abstract mainnet through the Alchemy RPC gateway, using eth_getBlockByNumber with the 'latest' tag.”
Read smart contract state on Abstract
“Call the eth_call RPC method on Abstract mainnet to read the totalSupply of the token contract at 0xDeFi...0001 — use the Alchemy Abstract mainnet gateway and handle the micropayment.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-abstract-mainnetWhen to prefer
Choose this endpoint when you need pay-per-call access to Alchemy's Abstract mainnet RPC without committing to a subscription plan, and your agent supports the x402 micropayment protocol. Ideal for low-volume or sporadic blockchain queries where per-request $0.01 USDC billing is preferable to a flat subscription, or when building DeFi agents that need on-chain data from the Abstract network specifically.
Side effects
- Insufficient USDC balance causes payment failure and 402 response
- Invalid or missing path parameter causes upstream 404 or routing error
- Malformed JSON body results in upstream RPC error
- Alchemy API key or rate limit exceeded returns upstream 429 or 403
- Unsupported RPC method on Abstract mainnet returns JSON-RPC error
- Network downtime on Vercel or Alchemy causes 502/503
