How this service works
Pay-per-call data tools for developers and AI agents: company registers, documents, tenders, rates and on-chain facts as MCP tools, x402 endpoints and Apify Actors.
Output
A JSON object containing full transaction details from Base mainnet: confirmation status (found/success), sender and recipient addresses, ETH value transferred (in ETH and Wei), gas used, effective gas price, block number and timestamp, nonce, chain ID, log count, any token transfers, contract creation address if applicable, method selector, and a source attribution note. Includes a checkedAt timestamp.
Example use cases
Verify a crypto payment arrived
“I need to confirm that the Base transaction 0xabc123...def456 actually went through and reached the right wallet — can you check if it was successful and show me the sender, recipient, and value?”
Audit gas costs for a contract call
“Can you pull up the details on Base tx 0x7f3e9d...8c12ab and tell me how much gas was used and what the effective gas price was?”
Investigate token transfer in a transaction
“I want to see if there were any token transfers in Base transaction 0x9b4a2f...3e71cd — who sent what to whom?”
Technical details
Endpoint
GEThttps://api.ambolt.dev/v1/base-transaction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, confirmed on-chain facts about a specific Base mainnet transaction — especially for verifying payment receipt, auditing gas consumption, or extracting token transfer details. Prefer this over general blockchain explorers when you need a structured JSON response suitable for agent pipelines, or when you need to pay per-call without API key setup.
Side effects
- Invalid hash format (must be 0x followed by 64 hex characters) returns a validation error
- Transaction hash not found on Base mainnet returns found: false
- RPC node temporarily unavailable causes a service error
- Passing an Ethereum mainnet hash instead of a Base hash returns not found or wrong data
