How this service works
HALOWERK kettenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns health and status information for each requested blockchain network, indicating whether each chain is reachable and operational at the time of the request.
Example use cases
Pre-transaction chain availability check
“Before I send this transaction, can you confirm that the Ethereum and Base networks are both healthy and online right now?”
Multi-chain DApp readiness check
“Check the health of all the chains my app uses — Ethereum, Arbitrum, Optimism, and Polygon — and tell me if any are having issues.”
Automated network monitoring alert
“Check whether the Base network is currently healthy so I know if my deployment pipeline can proceed.”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/chain/healthWhen to prefer
Use this endpoint when you need a quick, paid, on-demand health check for one or more EVM-compatible chains without maintaining your own RPC node monitoring infrastructure. Prefer this over building custom health checks when you need lightweight per-call pricing via the x402 micropayment protocol on Base Mainnet.
Side effects
- Invalid chain name provided — endpoint only accepts: ethereum, base, arbitrum, optimism, polygon, bsc
- Too many chains requested (max 6) or empty array (min 1)
- Network timeout if a chain RPC node is temporarily unreachable
- Payment failure if USDC balance on Base Mainnet is insufficient for the $0.003 fee
- x402 payment protocol not supported by client
