How this service works
Fast, low-cost Base data for autonomous agents. No API keys, no subscriptions; pay per call with USDC over x402.
Output
Returns a JSON object indicating whether the transaction was found, the EVM network ID (eip155:8453 for Base), whether the transaction succeeded, the block number it was included in, and the number of confirmations accumulated.
Example use cases
Confirm on-chain payment receipt
“I just sent a payment on Base with tx hash 0xabc123...def456 — can you confirm it succeeded and tell me how many confirmations it has so far?”
Verify NFT mint transaction
“Check whether this Base mint transaction 0xdeadbeef...cafe1234 was successful and what block number it landed in.”
Monitor smart contract execution
“I executed a contract call on Base — the tx hash is 0x9f8e7d...6c5b4a. Did it go through successfully and is it fully confirmed yet?”
Technical details
Endpoint
POSThttps://api.mach.gallery/api/base/receipt?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call lookup of a Base transaction receipt without API key setup — especially useful for autonomous agents that need to verify on-chain payment success or confirm contract execution on the Base L2 network. Prefer over direct RPC calls when you want a managed, low-latency abstraction billed per use in USDC.
Side effects
- Transaction hash not found (found: false) if the hash is invalid or not yet indexed
- Invalid hash format (not matching ^0x[0-9a-fA-F]{64}$) causes a validation error
- Payment failure via x402 if insufficient USDC balance
- Network or RPC timeout if Base node is congested
- Very recent transactions may show 0 or low confirmations
