What it returns

The brief of event-logs; prefer it unless you need every log. Same chains, parameters and 400s. It counts the logs, gives the first and last block and time, the 10 event signatures (topics[0]) with the most logs, and the 5 newest logs in full, undecoded. truncated is the full answer's: when true the counts are of the rows it listed.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of Event logs brief: counts per event and the newest logs of a contract
Field	Type	Description
`truncated`	boolean	The full answer's: `true` when it hit its row cap, so more logs match and the counts are of the rows listed.
`logCount`	integer	Logs in the full answer.
`firstBlock`	integer \| null	Block of the oldest log listed; `null` when none.
`lastBlock`	integer \| null	Block of the newest log listed; `null` when none.
`firstAt`	integer \| null	When the oldest log's block was mined, Unix seconds; `null` when unknown or none.
`lastAt`	integer \| null	When the newest log's block was mined, Unix seconds; `null` when unknown or none.
`events`	object[]	Up to 10 event signatures, most logs first.
`events[].topic0`	string \| null	The event signature hash; `null` for an anonymous event.
`events[].logs`	integer	Logs listed with it.
`latest`	object[]	The 5 newest logs, oldest first, each exactly as the full answer lists it.
`latest[].address`	string \| null

Raw event logs emitted by a contract
The full answer this one condenses
What does this transaction payload call?
Decodes a CALL's arguments; this endpoint reads raw LOGS instead, undecoded.
The most recently verified contracts on a chain
The chain's verified contracts, newest verification first, 50 per page: address, name, verification time, compiler, license, proxy type, transaction count and balance. RHC only.
The address lookup tables an authority controls
Lists the Solana address lookup tables one authority controls, with each table's status, slots and every address it holds.
Is this address a verified contract
Whether an address holds bytecode, whether its source is published and verified, its compiler and licence, and whether it is a proxy pointing at an implementation.
What a contract can do to a holder
Risk traits of a contract or spender address — what an approval to it would allow, and whether anything about it is flagged.
