Runway Workflow as an endpoint vs a Sume Format over the API

Runway lets an admin or editor publish a Workflow as an API endpoint with one click from the Web App, then a developer runs it from the Developer Portal or copies code with Get Code. Sume's equivalent is a Format: a saved recipe you call with POST /v1/formats/{handle}/{slug}/runs using an API key. The big differences are that Runway links two accounts and bills the Developer balance, while Sume uses one key with scopes and returns a typed result you define.

Setup and billing

What comes back

A Format run returns a receipt with status_url, result_url, events_url and cancel_url. Statuses are queued, processing, then completed, failed, canceled or skipped. With an output_schema, output comes back in your shape and primary_output_url points at the headline file.

curl -sS -X POST "https://api.sume.com/v1/formats/acme/live-commerce/runs" \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: order-8823-v1" \
  -d '{
    "instruction": "Vertical 9:16, no BGM.",
    "input": { "product_url": "https://shop.example.com/p/8823" },
    "output_schema": {
      "name": "acme/live-commerce/v1",
      "strict": true,
      "schema": {
        "type": "object",
        "additionalProperties": false,
        "required": ["full_video"],
        "properties": { "full_video": { "$ref": "SumeMediaFile#" } }
      }
    },
    "primary_output_key": "full_video",
    "generation_spend_cap_usd": 120
  }'

Edits do not touch a run in flight

Runway says each change to a published endpoint deploys immediately. On Sume, editing a Format's package never touches a run that is already in flight, because each run reads the package it started with. The version on the receipt is the proof of which recipe ran.

Pick by who builds

• Visual nodes built by a creative team, called by a developer: Runway's published Workflow.
• A recipe an agent follows, with a schema you own and webhooks or polling: a Sume Format.
• Whichever you choose, read how credits or dollars are charged before the first call.
