litefold-sdk 0.1.3

Python SDK for the LiteFold API

LiteFold Python SDK

Python client for the LiteFold Rosalind API. Designed for programmatic access by OpenClaw agents running in parallel (10–100+).

Install

cd LiteFoldPythonSDK
pip install -e .

Dependencies: httpx, click.

Quick Start

from litefold import Client

client = Client(api_key="lf_...", base_url="https://agentsapi.litefold.ai")

Chat Lifecycle

Create and send (fire-and-forget)

client.rosalind.create_chat(
    project="Default", chat_name="run-1",
    description="KRAS study", device="cpu",
)

client.rosalind.send_message(
    project="Default", chat_name="run-1",
    message="Describe KRAS G12D in cancer.",
    mode="pro",       # "max" | "pro" | "lite"
    depth="balanced",  # "quick" | "balanced" | "ultra"
)

send_message returns immediately — it does not block on the agent stream.

Check status

status = client.rosalind.chat_status(project="Default", chat_name="run-1")
status.is_running  # True while agent is working
status.status      # "running" | "completed" | "error" | "cancelled" | "unknown"

Poll until done

import time

while True:
    status = client.rosalind.chat_status(project="Default", chat_name="run-1")
    if not status.is_running:
        break
    time.sleep(5)

Reading Results

List chats

chats = client.rosalind.list_chats(project="Default", limit=5)
for c in chats:
    print(c.chat_name, c.total_cost_usd, c.device)

Blocks

Chat history is stored as an ordered list of blocks. Each block is one of:

content_type	What it is	Key fields
text	Assistant response text	.text, .assistant_message
thinking	Model thinking	.text
tool_use	Tool invocation	.tool_name, .tool_input
mcp_result	Tool output	.tool_name, .tool_result, .is_output_panel

total = client.rosalind.list_blocks(project="Default", chat_name="run-1")

blocks = client.rosalind.get_blocks(
    project="Default", chat_name="run-1",
    start=0, end=20,  # slice — omit for all blocks
)

for b in blocks:
    if b.assistant_message:
        print(b.assistant_message)
    elif b.content_type == "mcp_result":
        print(f"[{b.tool_name}] {b.tool_result}")

Bash outputs

bash = client.rosalind.get_bash_outputs(
    project="Default", chat_name="run-1",
    start=0, end=50,
)
for b in bash:
    print(f"$ {b.command}")
    print(f"  exit={b.exit_code}  output={b.output[:200]}")

Workspace files

ws = client.rosalind.workspace(project="Default", chat_name="run-1")

ws.list_folders()                          # ["scripts", "documents", "figures", ...]
ws.list_files(folder="scripts")            # [WorkspaceFile, ...]
ws.get_file_content("scripts/main.py")     # FileContent with .content

Files

Upload

# Upload from disk (single file or list)
result = client.files.upload("Default", "data/protein.pdb")
result = client.files.upload("Default", ["data/protein.pdb", "data/ligand.sdf"], folder="structure")

# Upload raw bytes
result = client.files.upload_bytes("Default", "notes.txt", b"Hello world")

print(result.completed, result.failed)  # 2, 0
for r in result.results:
    print(r.filename, r.status, r.format_type)

List

files = client.files.list("Default", folder="upload")
all_files = client.files.list_all("Default")
structures = client.files.list_by_format("Default", format_type="structure")
children = client.files.list_children("Default", parent_file_name="protein.pdb")

for f in files:
    print(f.file_name, f.folder, f.format_type)

Download

# Get text content
content = client.files.get_content("Default", "result.csv")

# Download as bytes
raw = client.files.download("Default", "protein.pdb")

# Download straight to disk
client.files.download_to("Default", "protein.pdb", "./output/")

# Get a presigned URL (for sharing / browser download)
url_info = client.files.get_url("Default", "protein.pdb", expires_in=3600)
print(url_info.url)

Metadata

info = client.files.get_metadata("Default", "protein.pdb")
print(info.format_type, info.created_at, info.metadata)

client.files.update_metadata("Default", "protein.pdb", metadata={"notes": "cleaned"})

Delete

client.files.delete("Default", "old_file.pdb")
client.files.delete_batch("Default", ["file1.sdf", "file2.sdf"])

Sync (local ↔ R2)

client.files.upsync("Default", folder="upload")    # local → cloud
client.files.downsync("Default", folder="structure") # cloud → local

Projects

client.projects.create(name="MyProject", description="...")
client.projects.list()       # ProjectList
client.projects.get("MyProject")
client.projects.delete("MyProject")

CLI

The SDK ships with a litefold CLI so you can do everything from your terminal without writing a script.

export LITEFOLD_API_KEY=lf_...

All commands accept --json for machine-readable output. Use --help on any command for full options.

Multi-Agent Usage

The SDK is designed for 10–100+ agents running concurrently:

• One client per process — the connection pool (200 sockets) handles all threads.
• One client per agent — also fine; each gets its own pool.
• Fire-and-forget — send_message returns instantly, agents poll chat_status at their own pace.
• Retry built-in — transient errors (429, 5xx, connection resets) are retried automatically with exponential backoff.

# Tune for your workload
client = Client(
    api_key="lf_...",
    base_url="https://agentsapi.litefold.ai",
    timeout=60.0,
    max_retries=3,
    retry_backoff=1.0,
    pool_max_connections=200,
    pool_max_keepalive=40,
)

Error Handling

from litefold import (
    LiteFoldError,          # base
    LiteFoldAPIError,       # HTTP error (has .status_code, .message)
    LiteFoldAuthError,      # 401/403
    LiteFoldNotFoundError,  # 404
    LiteFoldRateLimitError, # 429
    LiteFoldTimeoutError,   # polling timeout
)

try:
    client.rosalind.send_message(...)
except LiteFoldRateLimitError:
    print("Out of credits")
except LiteFoldAuthError:
    print("Bad API key")
except LiteFoldAPIError as e:
    print(f"HTTP {e.status_code}: {e.message}")
