everydeck (Python SDK)

The Python server SDK of everydeck: it reports the signals, errors and logs of your app's flows to everydeck.

pip install everydeck

import os
from everydeck import Everydeck

everydeck = Everydeck(
    endpoint=os.environ["EVERYDECK_URL"],
    credential="<server key of the environment>",
    release_key="auto",
    manifest_digest="<digest of the approved manifest>",
    heartbeat_interval=60,
    instance_id="api",
)
everydeck.signal("job.created", operation_id)

• signal(), error() and log() never block and never raise: they enqueue into a bounded in-memory buffer; a background thread sends batches (at most 50 events, 64 KiB, gzip-compressed).
• Retries only on 429, 5xx, timeout and network errors; Retry-After is honoured; final rejections are dropped and counted, never reported as sent.
• A buffer overflow is reported as a gap event, so everydeck shows a known data gap instead of silence.
• heartbeat_interval sends everydeck.sdk.heartbeat from the sender thread. Give each component a stable instance_id (for example "api", "worker").
• release_key="auto" derives the version from the deployment commit (EVERYDECK_RELEASE_KEY, GITHUB_SHA, VERCEL_GIT_COMMIT_SHA, RENDER_GIT_COMMIT, …) or local git.
• everydeck.verify.verify_everydeck_request checks everydeck's signature on bridge calls.
• Read bridge on FastAPI or Starlette: from everydeck.read_route import mount_read_bridge, SupabaseReadOnly and mount_read_bridge(app, SupabaseReadOnly(supabase_admin)) in the module that creates app add the route /everydeck/read/{rest:path} (outside the API schema); it reads EVERYDECK_URL and EVERYDECK_READ_BRIDGE_TOKEN from the environment when the first call arrives.
• Read bridge (0.3.0): everydeck.read_route.EverydeckReadBridge(endpoint, key, db) is the ready-made route for other frameworks. It fetches its read scope from everydeck (GET <endpoint>/v1/read-scope with the bridge key) and uses it only with everydeck's signature; no read-scope file, no read role, no views. db is the connection the app already has: PsycopgReadOnly(conninfo) runs every query in BEGIN READ ONLY, SupabaseReadOnly(client) reads through the app's Supabase client with select() only (GET requests, which PostgREST runs read-only; only tables in schemas the Supabase API exposes).
