eigenpal 0.7.2

Official Python SDK for the EigenPal API

eigenpal

Trigger EigenPal workflows from Python.

Install

pip install eigenpal

Requires Python 3.9+. Get an API key at studio.eigenpal.com → Settings → API Keys.

Quick start

import os
from pathlib import Path
from eigenpal import EigenpalClient, EigenpalValidationError

client = EigenpalClient(api_key=os.environ["EIGENPAL_API_KEY"])

# Pass a Path / file handle / { content, filename, mime_type }. The SDK
# uploads the request as multipart/form-data, no base64 needed.
result = client.workflows.executions.run_and_wait(
    "extract-invoice",
    input={"contract_document": Path("contract.pdf")},
)
print(result["finished"], result["output"])

Authentication

Generate an API key from the dashboard under Settings → API Keys, then pass it explicitly:

client = EigenpalClient(api_key=os.environ["EIGENPAL_API_KEY"])

The api_key argument always wins. If you omit it, the SDK falls back to EIGENPAL_API_KEY for convenience, handy in scripts where you'd be writing exactly the line above.

Self-hosted

Point the SDK at your own deployment via base_url:

client = EigenpalClient(
    api_key=os.environ["EIGENPAL_API_KEY"],
    base_url=os.environ.get("EIGENPAL_BASE_URL", "https://eigenpal.acme.internal"),
)

base_url likewise wins over the EIGENPAL_BASE_URL env fallback. Defaults to https://studio.eigenpal.com (the hosted cloud).

Starting runs

client.run(target, input=None, **options) starts a workflow or agent run. Targets can be strings like "workflows.extract-invoice" / "agents.invoice-agent" or structured objects like {"type": "workflow", "slug": "extract-invoice"}.

from pathlib import Path

# Async: returns immediately with the run id.
result = client.run(
    "workflows.extract-invoice",
    input={"contract_document": Path("contract.pdf")},
)
print(result.id)

# Sync: server holds the connection up to 60 seconds.
result = client.run(
    "workflows.extract-invoice",
    input={"contract_document": Path("contract.pdf")},
    wait_for_completion=60,
)
print(result.finished, result.output)

# Long-running: client-side polling (default 5min cap).
final = client.workflows.executions.run_and_wait(
    "extract-invoice",
    input={"contract_document": Path("contract.pdf")},
)
print(final["finished"], final.get("output"))

The input argument is the input map keyed by input name. Omit it for inputs-less runs. Put the workflow version or agent source ref in the target; other keyword args include overrides and wait_for_completion.

File inputs

Pass a pathlib.Path, an open file handle, or an explicit {"content": bytes, "filename": str, "mime_type": str} descriptor. The SDK auto-detects files and uploads as multipart/form-data (the same shape as curl -F):

from pathlib import Path

# Path: filename + mime type inferred.
client.run("workflows.extract-invoice", input={
    "contract_document": Path("contract.pdf"),
})

# File handle: filename inferred from .name.
with open("contract.pdf", "rb") as f:
    client.run("workflows.extract-invoice", input={"contract_document": f})

# Explicit dict: required for raw bytes.
client.run("workflows.extract-invoice", input={
    "contract_document": {
        "content": data,
        "filename": "contract.pdf",
        "mime_type": "application/pdf",
    },
})

Don't base64-encode files yourself. The SDK is multipart-first; base64 doubles the payload size and skips the optimised upload path.

Execution polling

summaries = client.runs.list(
    type="workflow",
    source="extract-invoice",
    status="failed,cancelled",
)

run = client.runs.get(run_id)
#   Run(id=..., type=..., finished=..., output=..., files=..., error=..., ...)

# Add heavier optional sections with `expand`.
run = client.runs.get(run_id, expand=["usage", "execution"])
print(run.output, run.files, run.error, run.usage, run.execution)

client.runs.cancel(run_id)

executions = client.runs.list(
    type="workflow",
    source="extract-invoice",
    status="failed",
    from_date="now()-7d",
    limit=50,
)

client.runs.cancel(run_id)

/api/v1/runs is the shared run API for workflow, agent, and eval runs. Use type="workflow"|"agent" and source="<workflowId-or-agentId>" to scope list calls.

Workflows

client.workflows.list(search="invoice", limit=20)
client.workflows.get("extract-invoice")
client.workflows.versions("extract-invoice")

Agents

client.agents.list(search="invoice")
client.agents.get("invoice-agent")

result = client.run("agents.invoice-agent", input={
    "invoice": Path("invoice.pdf"),
})

client.runs.get(result.id)
client.runs.cancel(result.id)

Agent run listing uses the same shared runs API with type_="agent" and the agent id or slug as source.

Errors

Every non-2xx response raises a typed subclass of EigenpalError:

HTTP	Class	Notes
400	EigenpalValidationError	.issues carries the per-field problems
401	EigenpalAuthError	Bad / missing API key
403	EigenpalForbiddenError	API trigger disabled, scope mismatch
404	EigenpalNotFoundError	Workflow / execution doesn't exist
429	EigenpalRateLimitError	.retry_after is the server-suggested wait (seconds)
5xx	EigenpalServerError
timeout	EigenpalTimeoutError

from eigenpal import EigenpalClient, EigenpalValidationError

client = EigenpalClient(api_key=os.environ["EIGENPAL_API_KEY"])

try:
    # First arg accepts the workflow slug ("extract-invoice") or id ("wf_abc123").
    result = client.workflows.executions.run_and_wait(
        "extract-invoice",
        input={"language": "en"},
    )
    print(result["finished"], result["output"])
except EigenpalValidationError as err:
    for issue in err.issues:
        print(f"{issue['field']}: {issue['message']}")
    raise
