How this service works
Every transaction receipt in one block, fetched as a single upstream read and summarised: tx count, succeeded vs failed, total gas used, total fees, log count, contract creations, tx-type mix - plus compact per-transaction rows (hash, from, to, status, gas used, effective gas price, fee, log count) capped at 300. Block analytics, failed-tx hunting, or 'who paid what in block N' without N separate receipt calls.
Output
Returns a JSON object containing: the block number, source (Alchemy), chainId, network name, a summary object (transaction type counts, failed/succeeded counts, total fee in Wei and native units, gas used, tx count, log count, contract creations), an array of per-transaction receipts (to, from, hash, type, index, feeWei, status, gasUsed, logCount, contractAddress, effectiveGasPriceGwei), total returned count, blockHash, and fetch timestamp.
Example use cases
Audit gas fees for a block
“Fetch the full receipt summary for block 20000000 on Base — I want to know the total gas used, total fees in ETH, and a breakdown of transaction types.”
Investigate failed transactions in a block
“Can you check block 19500000 on Ethereum and tell me how many transactions failed, what their hashes were, and how much gas they consumed? Show me up to 50 receipts.”
Monitor Polygon block activity
“Get the receipts for the latest block on Polygon and summarize how many transactions there were, how many created contracts, and what the total fees were.”
Technical details
Endpoint
POSThttps://agent402.tools/api/block-receiptsWhen to prefer
Choose this endpoint when you need comprehensive receipt-level data for an entire block across major EVM-compatible networks (Ethereum, Base, Polygon, Arbitrum, Optimism), including aggregated summaries and per-transaction status, fees, and gas. It is especially useful for on-chain analytics, block auditing, or fee monitoring where you want both a block-level summary and individual receipt details in a single call without setting up your own RPC infrastructure.
Side effects
- Invalid or non-existent block number returns an error or empty result
- Unsupported network name causes a validation error
- Limit value outside 0–300 range may be rejected or clamped
- Block not yet finalized (future block) returns not-found error
- Network congestion or upstream Alchemy timeout causes slow or failed response
