Fetch Latest API Reference

Before guiding or implementing any Runway API integration, retrieve the current API reference and use it as the source of truth.

Why This Matters

The Runway API is the official reference. Models, endpoints, request/response shapes, and versioning can change. Using the live docs ensures integration guidance and code match the latest API.

Steps

1. Fetch the API Reference

Retrieve the contents of:

https://docs.dev.runwayml.com/api/

Use your available fetch tool (e.g. mcp_web_fetch or equivalent) to load this URL. The page contains the full API reference: endpoints, request bodies, accepted values, and examples.

2. Use It Before Integrating

• Before writing or suggesting integration code for video, image, audio, uploads, characters, documents, or any other Runway API feature, use the fetched content as the authoritative reference.
• Prefer exact endpoint paths, model IDs, parameter names, and header values from the fetched reference over any cached or local documentation.
• If the fetched content conflicts with text in other skills (e.g. +rw-api-reference or an integrate skill), the fetched docs take precedence for that session.

3. When to Re-Fetch

• Re-fetch when the user asks to integrate a new capability or when you are unsure about an endpoint or parameter.
• Re-fetch when the user reports errors that might be due to API changes (e.g. invalid model name, changed request shape).

After Fetching

Proceed with the relevant integrate skill (+rw-integrate-video, +rw-integrate-image, +rw-integrate-audio, +rw-integrate-uploads, +rw-integrate-characters, +rw-integrate-documents, +rw-integrate-character-embed) using the retrieved reference to guide implementation.

Important Notes

• Base URL for the API is https://api.dev.runwayml.com.
• All requests require Authorization: Bearer <RUNWAYML_API_SECRET> and X-Runway-Version: 2024-11-06 (or the version stated in the fetched docs).
• Do not rely solely on bundled or in-repo API summaries when the user is integrating; the live docs are the source of truth.
