Example prompt: Can you pull up the full on-chain details for Base transaction 0x3a4f...c9b2 — I need to see the sender, receiver, value transferred, gas used, and whether it confirmed successfully?

## When to prefer this

Use this endpoint when you need on-chain transaction details specifically from the Base EVM network and want a simple REST API call without managing your own RPC node or Base node infrastructure. Ideal for agents needing quick, single-transaction lookups for verification, auditing, or debugging purposes on Base.

## Known failure modes

- Invalid or malformed transaction hash returns a 400 or 404 error
- Transaction hash from a different EVM chain (not Base) returns no result or an error
- Transaction not yet indexed returns empty or not-found response
- Network timeout or RPC node unavailability causes request failure
- Pending/unconfirmed transactions may return incomplete data
