List contract logs from a contract on the network

Search the logs of a specific contract across multiple contract calls. Chained logs are not included but can be found by calling /api/v1/contracts/{contractId}/results/{timestamp} or /api/v1/contracts/results/{transactionId}. When searching by topic a timestamp parameter must be supplied and span a time range of at most seven days.

Ordering

The order is governed by the combination of timestamp and index values. If the index param is omitted, the order is determined by the timestamp only.

Note: The default order for this API is currently DESC

Filtering

When filtering there are some restrictions enforced to ensure correctness and scalability.

The table below defines the restrictions and support for the endpoint

Query Param	Comparison Operator	Support	Description	Example
index	eq	Y	Single occurrence only. Requires the presence of timestamp	?index=X
	ne	N
	lt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=lte:X
	gt(e)	Y	Single occurrence only. Requires the presence of timestamp	?index=gte:X
timestamp	eq	Y	Single occurrence only.	?timestamp=Y
	ne	N
	lt(e)	Y	Single occurrence only. Optional second timestamp gt(e)	?timestamp=lte:Y
	gt(e)	Y	Single occurrence only. Optional second timestamp lt(e)	?timestamp=gte:Y

Both filters must be a single occurrence of gt(e) or lt(e) which provide a lower and or upper boundary for search.

Path Parameters

contractIdOrAddress · string · required

The ID or hex encoded EVM address (with or without 0x prefix) associated with this contract.

Pattern: ^(\d{1,10}\.){0,2}(\d{1,10}|(0x)?[A-Fa-f0-9]{40})$

Query Parameters

index · string

Contract log index

Pattern: ^((eq|gt|gte|lt|lte):)?\d{1,10}$

limit · integer<int32> · default: 25

The maximum number of items to return

Required range: 1 <= x <= 100

order · enum<string> · default: desc

The order in which items are listed

Available options: asc, desc

timestamp · string[]

The consensus timestamp as a Unix timestamp in seconds.nanoseconds format with an optional comparison operator. See unixtimestamp.com for a simple way to convert a date to the 'seconds' part of the Unix time.

Pattern: ^((eq|gt|gte|lt|lte|ne):)?\d{1,10}(.\d{1,9})?$

topic0 · string[]

Pattern: ^(0x)?[0-9A-Fa-f]{1,64}$

topic1 · string[]

The second topic associated with a contract log. Requires a timestamp range also be populated.

Pattern: ^(0x)?[0-9A-Fa-f]{1,64}$

topic2 · string[]

The third topic associated with a contract log. Requires a timestamp range also be populated.

Pattern: ^(0x)?[0-9A-Fa-f]{1,64}$
