akribes 0.22.0

Pythonic async client for the Akribes workflow server

akribes

Pythonic async client for the Akribes workflow server.

Requires Python 3.10+.

Install

pip install akribes
# or with optional OpenTelemetry support:
pip install 'akribes[otel]'

Quick start

import asyncio
from akribes_sdk import AkribesClient

async def main():
    async with AkribesClient("https://akribes.example.com", token="akribes_tk_...") as client:
        proj = client.project(2)
        output = await proj.script("summarize").run_and_await(brief="explain quantum")
        print(output.execution_id, output.result)

asyncio.run(main())

Construction

import os
from datetime import timedelta
from akribes_sdk import AkribesClient, RetryPolicy

client = AkribesClient(
    "https://akribes.example.com",
    token=os.environ["AKRIBES_TOKEN"],
    timeout=timedelta(seconds=30),
    retry=RetryPolicy(max_attempts=4),      # retries transients + 429 by default
    otel=True,                               # opt-in OTel auto-instrumentation
)

Project handles

proj = client.project(2)                              # sync, lazy
proj = await client.get_project("podesta-staging")    # async, resolves name → id
sandbox = await client.sandbox()                       # per-user sandbox project

Typed inputs (codegen)

Generate typed ScriptType[I, O] stubs from a live server:

akribes types pull --project podesta --lang python --out src/akribes_types/

Then:

from akribes_types.podesta import summarize   # ScriptType[I, O] with typed input/output

out = await proj.run(summarize, brief="hi", tone="formal")
# IDE knows brief: str, tone: Literal["formal","casual"]
print(out.execution_id, out.result)

Streaming

run = await proj.executions.run_stream("summarize", brief="hi")
async for evt in run:
    match evt.kind:
        case "agent_chunk": print(evt.chunk, end="")
        case "task_end":    print(f"\n[task {evt.task!r} done]")
        case "error":       print(f"\n[error {evt.message}]")
output = await run.output()

Document ingest

from pathlib import Path

# One-liner
result = await proj.documents.ingest_and_wait(Path("invoice.pdf"))

# With progress
handle = proj.documents.ingest(Path("invoice.pdf"))
async for evt in handle:
    print(evt)
result = await handle.result()

Subscribe (long-lived events)

async with proj.events.subscribe(interests=[{"script_name": "summarize"}]) as sub:
    async for evt in sub:
        print(evt)

Heartbeat runs for the lifetime of the subscription only — not automatically on client construction.

Pagination

async for script in proj.scripts.list():
    print(script.name)

# Or materialise
scripts = await proj.scripts.list().to_list()
first   = await proj.scripts.list().first()
top10   = await proj.scripts.list().take(10)

Error handling

from akribes_sdk import (
    AkribesError, AuthError, NotFoundError, TransientError,
    RateLimitError, ScriptError, AkribesTimeoutError,
)

try:
    output = await proj.run_and_await("summarize", brief="hi")
except AuthError:        # 401/403
    ...
except NotFoundError:    # 404
    ...
except TransientError:   # 502/503 (retried by default)
    ...
except RateLimitError:   # 429 (retried by default, respects Retry-After)
    ...
except ScriptError as e: # workflow failed; e.error_kind, e.execution_id
    ...

Tokens

from datetime import timedelta
minted = await client.tokens.mint(
    scopes={"projects": "*", "role": "admin"},
    expires_in=timedelta(hours=8),
    label="web-session",
    user_email="[e-mail]",
)
print(minted.token)   # ship to the browser

Authentication

AkribesClient accepts either a service token (long-lived, set via AKRIBES_SERVICE_TOKEN_<NAME>=<scope>:<secret> on the server) or a scoped token (akribes_tk_... — legacy aura_tk_... still accepted — minted via client.tokens.mint(...)).

Prefer Authorization: Bearer over ?token=… (#789)

AkribesClient always sends the token in the Authorization header for HTTP requests and WebSocket upgrades. The ?token=… query-string form exists only because browser EventSource / WebSocket constructors cannot set arbitrary headers — treat it as a browser-only escape hatch.

For CLIs, scripts, and backend services, avoid ?token=… because:

• Reverse proxies, ingress controllers, and CDNs log the full URL (including the token) in access logs by default.
• CI runners (Forgejo Actions, GitHub Actions) echo curl commands into job logs.
• Browsers leak ?token= in the Referer header on cross-origin sub-resource requests.

The server stamps X-Token-Source: query-param on responses to any request that used the query fallback so operators can chart adoption.
