render-lab-tasks-replicate

Python port of the twelve Replicate prediction, training, file, and model tasks. Install with pip install render-lab-tasks-replicate render==1.0.1 once released. Import wrapped tasks and raw injectable implementations from render_lab_tasks_replicate.tasks. The package root is registration-free. Task names and JSON fields match TypeScript.

Environment

REPLICATE_API_TOKEN is read lazily on the first Replicate request. Source URL requests use only the headers supplied in their media source; vendor credentials are never added.

Behavior and verification

Await operations check status once and let the durable task retry policy poll again. The HTTP adapter makes one attempt per call. Cancellation and deletion converge on 404/409 responses as in TypeScript. Prediction/training outputs retain nested JSON and expose HTTPS media URLs separately. Inline media is capped at 1 MiB. File downloads stop when their configured source byte limit is exceeded (default 100 MiB). See ADR-0013 for deliberate retry and media validation differences from the TS SDK. No live Replicate verification has been performed; credentials and live checks are tracked in the repository testing backlog.

Webhook adapter

render_lab_tasks_replicate.webhooks.replicate_adapter(on_event, ...) returns a registration-free adapter for render_lab_triggers. The callback receives the verified event and returns {"task": "namespace.task", "args": [event]} or None. The signing credential REPLICATE_WEBHOOK_SIGNING_SECRET is read inside verification unless provided explicitly. Importing this module does not register tasks. Signature checks use the raw body; live delivery remains in the testing backlog.
