stablebrowse 0.1.1

Python client for the stablebrowse browser agent API

stablebrowse (Python)

Python client for the stablebrowse browser agent API.

Install

From PyPI (once published):

pip install stablebrowse

From source (for local development):

cd sdks/python
pip install -e .

Requires Python 3.9+. Depends on httpx.

Quick start

from stablebrowse import Stablebrowse

# Bearer token comes from either the constructor or the
# STABLEBROWSE_API_KEY environment variable.
client = Stablebrowse(api_key="sb_live_...")

# (Optional) upload per-end-user social-media credentials.
client.end_users("alice").credentials.set(
    twitter_auth_token="...",
    twitter_ct0="...",
)

# Sync-feeling submit. Polls internally until the task terminates.
result = client.tasks.run(
    end_user_id="alice",
    task="find the top AI tweets today",
)
print(result.result)
print(f"cost: ${result.total_cost_usd:.4f}")

Async primitives

If you want to drive the poll loop yourself — for example, to push progress into your own queue, or to run many submissions in parallel with your own scheduler — use the raw methods:

submission = client.tasks.submit(end_user_id="alice", task="...")
while True:
    task = client.tasks.get(submission.task_id)
    if task.is_terminal:
        break
    time.sleep(2)

Multi-turn conversations

Pass the session_id you got from the first call to continue a conversation:

first = client.tasks.run(end_user_id="alice", task="who's trending on X?")
follow = client.tasks.run(
    end_user_id="alice",
    task="what about in music specifically?",
    session_id=first.session_id,
)

The server builds previousContext from the last completed turn so the agent has the earlier answer when it reasons about the follow-up.

End users and credentials

Each business scopes end-users by opaque identifier — "alice" inside your business is independent of any other business's "alice":

alice = client.end_users("alice")

alice.credentials.set(
    tiktok_session_id="...",
    tiktok_csrf_token="...",
)

status = alice.credentials.get()
assert status.platforms["tiktok"] is True

# Remove all creds
alice.credentials.delete()

# Or a specific subset
alice.credentials.delete(fields=["twitter_auth_token", "twitter_ct0"])

Field names are snake_case in Python and get translated to camelCase on the wire automatically.

API key management

Only usable with a Cognito JWT (see the web dashboard). API-key bearer tokens cannot mint more keys — that's by design to contain a leak.

# Typically used from a short-lived admin script, not from app code.
keys = client.api_keys.list()
new = client.api_keys.create(label="production")
print("save this — you won't see it again:", new.secret)
client.api_keys.revoke(new.prefix)

Errors

Every exception derives from StablebrowseError:

• TaskFailed — run() saw the task finish with status=failed. The failed Task is on .task.
• TaskTimeout — the poll deadline expired before the task terminated. The still-running Task is on .task so you can keep polling.
• StablebrowseError — every other HTTP or transport error. .status_code and .body are populated when the server returned structured JSON.

Configuration

The constructor reads a couple of env vars if you don't pass them:

• STABLEBROWSE_API_KEY — bearer token
• STABLEBROWSE_BASE_URL — override the API base, useful for pointing at beta or a local gateway
