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 the Alchemy ETH Mainnet Beacon API, passed through as-is after successful micropayment, including the content type. Typically contains Ethereum beacon chain JSON data such as validator info, slot details, epoch data, or finality checkpoints.
Example use cases
Check Ethereum validator status
“Look up the current status of Ethereum validator index 12345 on the beacon chain mainnet — fetch it from the Alchemy beacon API at /eth/v1/beacon/states/head/validators/12345.”
Retrieve latest beacon chain slot
“Get me the latest finalized slot and epoch from the Ethereum mainnet beacon chain — use the path /eth/v1/beacon/states/finalized/finality_checkpoints.”
Monitor ETH beacon chain head
“Fetch the current beacon chain head block from the Alchemy ETH mainnet beacon API at /eth/v1/beacon/blocks/head and return the slot number and block root.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/alchemy-eth-mainnetbeaconWhen to prefer
Use this endpoint when you need per-call, pay-as-you-go access to the Alchemy ETH Mainnet Beacon API without managing an Alchemy API key directly, and when operating in an x402-compatible agent or wallet context that can handle USDC micropayments on-chain. Prefer this over direct Alchemy API access when you want metered billing at $0.01/call and do not want to commit to a subscription.
Side effects
- Insufficient USDC balance or failed x402 payment causes request to be rejected before forwarding
- Invalid or malformed path results in upstream 404 or 400 from Alchemy
- Alchemy API rate limit or downtime causes upstream 429 or 5xx error
- Malformed query object or body causes gateway parsing error
- Network timeout on the Vercel proxy layer
