How this service works
HALOWERK kettenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns the current status of the specified transaction on the given chain — typically including whether it is pending, confirmed, or failed, along with relevant confirmation metadata such as block number, timestamp, or receipt details.
Example use cases
DeFi transfer confirmation check
“I just sent USDC on Ethereum — can you check if transaction 0xabc123...def456 has been confirmed yet?”
Cross-chain bridge status verification
“I used a bridge to move funds from Arbitrum and the hash is 0x9f1e...3d80 — has that transaction gone through on Arbitrum?”
BSC payment receipt validation
“Someone claims they paid me on BSC with tx hash 0xd4c7...88fa — can you verify whether that transaction actually succeeded?”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/tx/statusWhen to prefer
Use this endpoint when you need a quick, paid-per-call lookup of a specific EVM transaction status across Ethereum, Base, Arbitrum, Optimism, Polygon, or BSC without maintaining your own RPC infrastructure. Particularly useful for agents that only occasionally need on-chain tx verification and prefer pay-per-use over subscription RPC plans.
Side effects
- Invalid tx_hash format (not matching 0x + 64 hex chars) results in a validation error
- Chain not supported or misspelled returns an error
- Transaction hash does not exist on the specified chain returns not-found
- Network connectivity issues to the target chain's RPC may cause timeouts
- Payment failure via x402 protocol prevents the request from being processed
