Trajectory SDK
Generated Python client for the Trajectory API, with high-level workflows for uploading trajectories, telemetry, and runtime-backed benchmarks.
Install
pip install trajectory-sdk
Install the optional agent integration used by the full CLI with:
pip install "trajectory-sdk[cli]"
Quick start
Set TRAJECTORY_API_KEY, then create a client:
from trajectory import Client
client = Client()
benchmarks = client.benchmarks.list(limit=10)
Managed benchmark runtimes inject TRAJECTORY_TOKEN, TRAJECTORY_BASE_URL,
MODEL_ENDPOINT_ID, and TRAJECTORY_TID. The same client uses them for inference, rewards, and
completion:
from trajectory import Client
client = Client()
response = client.chat.completions.create(model="policy", messages=messages)
client.trajectories.log_reward(reward_id="primary", name="correct", value=reward)
client.trajectories.complete(termination_reason="ENV_DONE")
Explicit authentication, URLs, model endpoint headers, and trajectory IDs continue to override the runtime environment.
SDK-owned HTTP clients use a 600-second read/write/pool timeout and a 5-second connection timeout.
Supplying http_client= inherits that client's timeouts, including a bare HTTPX client's 5-second
default. An explicit Client(timeout=...) overrides the supplied client; a resource method's
timeout= overrides that request. timeout=None disables timeouts. Retry counts are unchanged.
The generated resource methods map directly to the public HTTP API. Higher-level operations that
coordinate multiple API calls are available from trajectory.lib:
from trajectory import Client
from trajectory.lib import ingest_events
client = Client()
result = ingest_events(
client,
[
{
"event_type": "agent.completed",
"session_id": "session-123",
"timestamp": "2026-08-28T00:00:00+00:00",
"properties": {"model": "example-model"},
}
],
)
print(result.ingested, result.skipped)
LiteLLM harnesses
Starting with SDK 0.6.6, an existing LiteLLM harness can use this import for policy calls:
from trajectory.lib.litellm import completion
response = completion(model=model, messages=messages, temperature=1.0)
This always uses the injected Trajectory endpoint and credentials. Messages and tools are unchanged.
Keep user/judge calls on native LiteLLM and retain the original loop and grader, then report their
result with the existing
client.trajectories.log_reward(...) and client.trajectories.complete(...) methods.
Command line
The package installs a handwritten trajectory command that delegates API operations to the same
generated client and high-level workflows:
export TRAJECTORY_API_KEY="tj_key_..."
trajectory trajectories upload trajectories.json --dataset my-dataset
trajectory telemetry ingest events.json
trajectory traces upload trajectories.json --events events.json --dataset my-dataset
trajectory secrets set OPENAI_API_KEY
trajectory secrets list
API-backed commands use a 30-minute timeout by default. Override it with --timeout SECONDS.
The existing repository and benchmark tools remain available from the new CLI package:
trajectory bench validate ./benchmark
trajectory bench push ./benchmark --build-images
trajectory extract harness
Benchmark pushes use your organization's only Agent, or create Default Agent if none exists.
With multiple Agents, add --agent-id agt_example to select the owner.
Development
uv run pytest
uv run ruff check .
uv run ruff format --check .
The generated client lives in src/trajectory/. Handwritten workflows live in
src/trajectory/lib/, the handwritten CLI lives in cmd/trajectory/cli/trajectory_cli/, and tests live in
tests/.
