traces

List traces

List traces for the project (paginated).

Workspace-scoped: filters by workspace_id when available. When target_manifest_id is provided:

Traces are filtered to only those that existed during the target manifest’s active period (between its created_at and the next manifest’s created_at).
Each trace is enriched with a compat object showing its compatibility against that manifest, computed on-demand if not already cached.

Multi-agent filters:

child_agent_name: find parent traces where a child agent matches this name
child_status: further filter those children by status (e.g., ‘error’)

X-Workspace-Id

Query Parameters

limit

integer

default:20

Required range: 1 <= x <= 100

offset

integer

default:0

Required range: x >= 0

status

enum<string> | null

Filter by trace status. Allowed: success/error/degraded.

Available options:

success,

error,

degraded

agent_name

string | null

eval_verdict

string | null

Filter by eval verdict (pass/fail/keep/drop/review/...), or 'unevaluated' for traces with no verdict yet, or 'evaluated' for any trace that has a verdict.

source_type

enum<string> | null

Filter by trace source_type. See ingest allowlist for valid values.

Available options:

production,

test,

evaluation,

sdk,

manual,

synthetic,

development,

sandbox,

distillation,

snapshot,

file,

url,

eval_replay,

sample,

demo,

hosted_trial

manifest_id

string | null

Full-text search across user_input, final_output, and agent_name

include_fixtures

boolean

default:true

When false, drop platform-harness fixture agents (__, live-, cuj*, soak-*, …) from the listing — the UI's default. Defaults to true for SDK/API back-compat. Ignored when an explicit agent/skill/tool filter is set (asking by name always works).

target_manifest_id

string | null

Show compatibility of traces relative to this manifest

child_agent_name

string | null

Filter parent traces by child agent name (multi-agent)

child_status

enum<string> | null

Filter child agent matches by status. Allowed: success/error/degraded.

Available options:

success,

error,

degraded

tool_name

string | null

Filter to traces that invoked the named tool (uses ToolCallIndex)

skill_name

string | null

Filter to traces where the named skill was activated (uses trace_skill_activation). Backs the owner skill-detail live-traces panel.

prompt_version

integer | null

Filter to traces whose agent ran this saved prompt version (the decimal.prompt.version agent_config() records on the agent span). Each listed trace carries its record as prompt.

Required range: x >= 1

prompt_source

string | null

fallback: only traces whose agent ran on the fallback= prompt in its code, because DecimalAI was unreachable or had no prompt saved for it (decimal.prompt.source on the agent span).

Allowed value: "fallback"

has_spans

boolean | null

When true, return only traces that recorded at least one span — this filters out empty hello-world traces from SDK setup that would otherwise clutter an investigation. When false, return only the empty-span traces. Omit the parameter to get both.

has_llm_calls

boolean | null

Symmetric filter for traces with 0 LLM calls.

sort

enum<string> | null

Order results by the given field. Prefix '-' for descending. Defaults to '-created_at'. Unknown values 422 instead of being silently ignored.

Available options:

-created_at,

created_at,

-started_at,

started_at

started_at_from

string<date-time> | null

Inclusive lower bound on RunTrace.started_at (ISO 8601). Malformed dates 422 via Pydantic typing instead of being silently ignored.

started_at_to

string<date-time> | null

Inclusive upper bound on RunTrace.started_at (ISO 8601). Same validation behavior as started_at_from.

compat_status

string | null

Filter to traces with this compatibility verdict against target_manifest_id. Values: keep / repair / replay / drop. Requires target_manifest_id to be set for authoritative scoping; otherwise falls back to RunTrace.compat_status (a less-precise denormalized field).

experiment

string | null

Only traces whose routing call this experiment (an agent's skill holdout or prompt split) put in a group. Every listed trace carries its group as experiment.

Maximum string length: 36

experiment_arm

enum<string> | null

With experiment, one group: a holdout's held_out (the skill was withheld) or with, a prompt split's a (the current prompt) or b (the new one).

Available options:

held_out,

with,

a,

b
