How this service works
API Gateway: Alchemy blockchain API (key in path)
Output
The raw Alchemy API JSON response for the requested path and method — including blockchain state, balances, NFT data, transaction info, or any other Alchemy endpoint output, identical to calling Alchemy directly.
Example use cases
Example prompt
“Use the Alchemy API gateway to call eth_getBalance for address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum mainnet and tell me the current balance in ETH.”
Technical details
Endpoint
POSThttps://httpay.xyz/api/gateway/alchemy/%7B*path%7D/*When to prefer
Choose this endpoint when you need to call any Alchemy blockchain API without provisioning your own Alchemy API key or subscription — ideal for agents making occasional or unpredictable Alchemy calls on a pay-per-use basis via x402 micropayments, especially on Base or Ethereum.
Side effects
- Invalid or unsupported Alchemy path returns 404 or passthrough error
- Payment not processed (x402 flow fails) — request is rejected before reaching Alchemy
- Alchemy-side errors (rate limits, invalid params) returned as-is from upstream
- Malformed request body causes Alchemy to return a JSON-RPC error
- Network not supported by the Alchemy path provided
