Client overview

The Python llama-cloud-services SDK provides AsyncAgentDataClient for working with the Agent Data API.

import httpx
import os
from pydantic import BaseModel
from llama_cloud_services.beta.agent_data import AsyncAgentDataClient
from llama_cloud.client import AsyncLlamaCloud

class ExtractedPerson(BaseModel):
    name: str
    age: int
    email: str

project_id = os.getenv("LLAMA_DEPLOY_PROJECT_ID")

# Base URL and API key (if running outside LlamaCloud)
base_url = os.getenv("LLAMA_CLOUD_BASE_URL")
api_key = os.getenv("LLAMA_CLOUD_API_KEY")

# Reusable async HTTP client with optional project scoping
http_client = httpx.AsyncClient(headers={"Project-Id": project_id} if project_id else None)

# Optional: base client for other SDK operations
base_client = AsyncLlamaCloud(
    base_url=base_url,
    token=api_key,
    httpx_client=http_client,
)

# Only set when deployed in LlamaCloud (falls back inside the Agent Data client)
deployment_name = os.getenv("LLAMA_DEPLOY_DEPLOYMENT_NAME")

client = AsyncAgentDataClient(
    type=ExtractedPerson,
    collection="extracted_people",
    # If omitted, uses LLAMA_DEPLOY_DEPLOYMENT_NAME or "_public"
    deployment_name=deployment_name,
    client=base_client,
)

Create, Get, Update, Delete

person = ExtractedPerson(name="John Doe", age=30, email="john@example.com")
created = await client.create_item(person)
fetched = await client.get_item(created.id)
updated = await client.update_item(created.id, ExtractedPerson(name="Jane", age=31, email="jane@example.com"))
await client.delete_item(updated.id)

Retry behavior: Network errors (timeouts, connection errors, retriable HTTP statuses) are retried up to 3 times with exponential backoff.

Notes:

• Updates overwrite the entire data object.
• get_item raises an httpx.HTTPStatusError with status code 404 if not found.

Search

You can filter by data fields and by created_at/updated_at (top-level fields). Sort using a comma-delimited list of fields; the data. prefix is required when sorting by data fields. The default page size is 50 (max 1000).

results = await client.search(
    filter={
        # Data fields
        "age": {"gte": 21, "lt": 65},
        "status": {"eq": "active"},
        "tags": {"includes": ["python", "ml"]},
        # Top-level timestamps (ISO strings accepted)
        "created_at": {"gte": "2024-01-01T00:00:00Z"},
    },
    order_by="data.name desc, created_at",
    page_size=50,
    offset=0,
    include_total=True,  # request only on the first page if needed
)

for item in results.items:
    print(item.data)

print(results.has_more, results.total)

Sorting:

• Example: "data.name desc, created_at".
• If no sort is provided, results default to created_at desc.

Pagination:

• Use offset and page_size. The server may return has_more and a next_page_token (SDK exposes has_more).

Aggregate

Group data by one or more data fields, optionally count items per group, and/or fetch the first item per group.

agg = await client.aggregate(
    filter={"status": {"eq": "active"}},
    group_by=["department", "role"],
    count=True,
    first=True,  # return the earliest item per group (by created_at)
    order_by="data.department asc, data.role asc",
    page_size=100,
)

for group in agg.items:  # items are groups
    print(group.group_key)  # {"department": "Sales", "role": "AE"}
    print(group.count)      # optional
    print(group.first_item) # optional dict

Details:

• group_by: dot-style data paths (e.g., "department", "contact.email").
• count: adds a count per group.
• first: returns the first data item per group (earliest created_at).
• order_by: uses the same semantics as search (applies to group key expressions).
• Pagination uses offset and page_size similarly to search.
