Integrate Stainless SDK for type-safe API client generation

[Claude]

Implements automated SDK generation infrastructure to productize EventRelay's API, enabling external developers to consume the Video-to-Anything pipeline via type-safe Python and TypeScript clients.

OpenAPI Specification

• Auto-generated spec from FastAPI backend (2,799 lines, OpenAPI 3.1.0)
• 40 endpoints with 28 Pydantic component schemas
• Script: scripts/generate_openapi.py regenerates from route definitions

Stainless Configuration

.stainless.yaml defines SDK generation for:

• Python: eventrelay-sdk → PyPI
• TypeScript: @groupthinking/eventrelay → npm
• Enabled: retries, pagination, streaming, error handling

CI/CD Pipeline

.github/workflows/stainless-sdk.yml automates:

1. OpenAPI spec validation on changes
2. SDK generation via Stainless API
3. Test execution on generated code
4. Publishing to PyPI (OIDC) and npm (token auth) on release tags
5. PR creation when spec changes

Usage Examples

Python:

from eventrelay import EventRelay

client = EventRelay(api_key="...")
job = client.videos.process(video_url="https://youtube.com/...", language="en")
status = client.videos.wait_for_completion(job.job_id)
events = client.events.extract(transcript=status.transcript)

TypeScript:

import { EventRelay } from '@groupthinking/eventrelay';

const client = new EventRelay({ apiKey: "..." });
const job = await client.videos.process({ video_url: "https://youtube.com/..." });
const status = await client.videos.waitForCompletion(job.job_id);

Documentation

• docs/SDK_INTEGRATION.md: Usage patterns, error handling, pagination, streaming
• docs/STAINLESS_SETUP.md: Setup guide for Stainless account, PyPI/npm publishing
• docs/STAINLESS_IMPLEMENTATION_SUMMARY.md: Architecture and strategic impact

Import Path Fixes

Fixed module resolution errors blocking OpenAPI generation:

• src/shared/youtube/__init__.py: Changed src.youtube_extension → youtube_extension
• src/youtube_extension/services/workflows/transcript_action_workflow.py: Changed src.shared.youtube → shared.youtube

Next Steps

Requires manual setup to activate SDK publishing:

1. Add STAINLESS_API_KEY secret (from stainless.com)
2. Configure PyPI trusted publisher for eventrelay-sdk
3. Add NPM_TOKEN secret for @groupthinking/eventrelay
4. Create v1.0.0 release to trigger first publish

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh issue view 94 --repo groupthinking/EventRelay --json number,title,body,state,url /home/REDACTED/.nvm/nvm.sh /home/REDACTED/.nvm/package.json /home/REDACTED/.nvm/rename_test.sh /home/REDACTED/.nvm/test (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>🟡 Integrate Stainless SDK for type-safe API client generation</issue_title>
<issue_description>## Context (from Architecture Diagram)
The 'Video-to-Anything' architecture specifies a Stainless SDK layer between the 4-step pipeline and external tools/services. Purpose: 'Auto-generates type-safe API clients from OpenAPI specs to accelerate development velocity.'

Current State

• The pipeline calls GitHub API, Vercel API, and Gemini API via raw aiohttp/requests
• No OpenAPI spec exists for the EventRelay backend itself
• No type-safe clients — all API calls are string-typed dictionaries

Strategic Execution Path (from diagram)

Phase 2 (1-2 weeks): 'Stainless + External API' — Monetization through productizing the pipeline as a consumable API

Tasks

1. Generate OpenAPI spec for EventRelay's FastAPI backend (FastAPI does this automatically)
2. Evaluate Stainless for SDK generation from the OpenAPI spec
3. Create typed Python + TypeScript client SDKs for the video-to-software pipeline
4. Publish SDK to PyPI/npm so external users can call the pipeline programmatically

Why This Matters

This converts EventRelay from a tool into a platform — other developers can integrate Video-to-Anything into their own apps via a clean SDK.

Additional Suggestion:

Auto-generated .egg-info package metadata files are tracked in git despite being in .gitignore, creating merge conflict risk and build reproducibility issues

[vercel]

TypeScript SDK generation job missing the 'Upload OpenAPI spec to Stainless' step that is present in the Python SDK job, creating an inconsistency that could cause generation failures.

Closing: duplicate of #95 which is the most comprehensive Stainless SDK implementation (10.8K additions, dual Python+TypeScript SDKs, tests). Keeping #95 as the candidate.
