Query Parameters

limitinteger

Limit the number of objects to return

Minimum: 0

starting_afterstring

Pagination cursor id.

For example, if the final item in the last page you fetched had an id of foo, pass starting_after=foo to fetch the next page. Note: you may only pass one of starting_after and ending_before

Format: "uuid"

ending_beforestring

Pagination cursor id.

For example, if the initial item in the last page you fetched had an id of foo, pass ending_before=foo to fetch the previous page. Note: you may only pass one of starting_after and ending_before

Format: "uuid"

idsAny properties in string, array<string>

Filter search results to a particular set of object IDs. To specify a list of IDs, include the query param multiple times

experiment_namestring

Name of the experiment to search for

project_namestring

Name of the project to search for

org_namestring

Filter search results to within a particular organization

Create experiment

Create a new experiment. If there is an existing experiment in the project with the same name as the one specified in the request, will return the existing experiment unmodified

Authorization

In: header

Request Body (Optional)

Any desired information about the new experiment object

project_id
Required
string

Unique identifier for the project that the experiment belongs under

Format: "uuid"

namestring | null

Name of the experiment. Within a project, experiment names are unique

descriptionstring | null

Textual description of the experiment

repo_infoobject | null

Metadata about the state of the repo when the experiment was created

base_exp_idstring | null

Id of default base experiment to compare against when viewing this experiment

Format: "uuid"

dataset_idstring | null

Identifier of the linked dataset, or null if the experiment is not linked to a dataset

Format: "uuid"

dataset_versionstring | null

Version number of the linked dataset the experiment was run against. This can be used to reproduce the experiment after the dataset has been modified.

publicboolean | null

Whether or not the experiment is public. Public experiments can be viewed by anybody inside or outside the organization

metadataobject | null

User-controlled metadata about the experiment

ensure_newboolean | null

Normally, creating an experiment with the same name as an existing experiment will return the existing one un-modified. But if ensure_new is true, registration will generate a new experiment with a unique name in case of a conflict.

GET/v1/experiment/{experiment_id}/fetch

Authorization

Authorization
Required
Bearer <token>

In: header

Path Parameters

experiment_id
Required
string

Experiment id

Format: "uuid"

Query Parameters

limitinteger

limit the number of traces fetched

Fetch queries may be paginated if the total result size is expected to be large (e.g. project_logs which accumulate over a long time). Note that fetch queries only support pagination in descending time order (from latest to earliest _xact_id. Furthermore, later pages may return rows which showed up in earlier pages, except with an earlier _xact_id. This happens because pagination occurs over the whole version history of the event log. You will most likely want to exclude any such duplicate, outdated rows (by id) from your combined result set.

The limit parameter controls the number of full traces to return. So you may end up with more individual rows than the specified limit if you are fetching events containing traces.

Minimum: 0

max_xact_idstring

DEPRECATION NOTICE: The manually-constructed pagination cursor is deprecated in favor of the explicit 'cursor' returned by object fetch requests. Please prefer the 'cursor' argument going forwards.

Together, max_xact_id and max_root_span_id form a pagination cursor

Since a paginated fetch query returns results in order from latest to earliest, the cursor for the next page can be found as the row with the minimum (earliest) value of the tuple (_xact_id, root_span_id). See the documentation of limit for an overview of paginating fetch queries.

max_root_span_idstring

DEPRECATION NOTICE: The manually-constructed pagination cursor is deprecated in favor of the explicit 'cursor' returned by object fetch requests. Please prefer the 'cursor' argument going forwards.

Together, max_xact_id and max_root_span_id form a pagination cursor

Since a paginated fetch query returns results in order from latest to earliest, the cursor for the next page can be found as the row with the minimum (earliest) value of the tuple (_xact_id, root_span_id). See the documentation of limit for an overview of paginating fetch queries.

versionstring

Retrieve a snapshot of events from a past time

The version id is essentially a filter on the latest event transaction id. You can use the max_xact_id returned by a past fetch as the version to reproduce that exact fetch.

Fetch queries may be paginated if the total result size is expected to be large (e.g. project_logs which accumulate over a long time). Note that fetch queries only support pagination in descending time order (from latest to earliest _xact_id. Furthermore, later pages may return rows which showed up in earlier pages, except with an earlier _xact_id. This happens because pagination occurs over the whole version history of the event log. You will most likely want to exclude any such duplicate, outdated rows (by id) from your combined result set.

The limit parameter controls the number of full traces to return. So you may end up with more individual rows than the specified limit if you are fetching events containing traces.

Minimum: 0

cursorstring | null

An opaque string to be used as a cursor for the next page of results, in order from latest to earliest.

The string can be obtained directly from the cursor property of the previous fetch query

max_xact_idstring | null

DEPRECATION NOTICE: The manually-constructed pagination cursor is deprecated in favor of the explicit 'cursor' returned by object fetch requests. Please prefer the 'cursor' argument going forwards.

Together, max_xact_id and max_root_span_id form a pagination cursor

Since a paginated fetch query returns results in order from latest to earliest, the cursor for the next page can be found as the row with the minimum (earliest) value of the tuple (_xact_id, root_span_id). See the documentation of limit for an overview of paginating fetch queries.

max_root_span_idstring | null

DEPRECATION NOTICE: The manually-constructed pagination cursor is deprecated in favor of the explicit 'cursor' returned by object fetch requests. Please prefer the 'cursor' argument going forwards.

filtersarray<object> | null

A list of filters on the events to fetch. Currently, only path-lookup type filters are supported, but we may add more in the future

versionstring | null

Retrieve a snapshot of events from a past time

The version id is essentially a filter on the latest event transaction id. You can use the max_xact_id returned by a past fetch as the version to reproduce that exact fetch.
