Api Schema Extractor

Who is this for?

You are the integrations dev connecting one new API per manual run, and this Gemini scraping workflow searches, scrapes and extracts JSON schema. Each API needs docs opened, endpoints copied to notes, and fields and enums typed out.

What problem does this solve?

You open docs, copy endpoints into notes, then type fields and enums. When you run it manually, the flow searches for docs, scrapes pages, classifies with Gemini, and builds JSON schema to Drive. You just approve extracted operations instead of typing each field yourself.

What this workflow does

1. Web Search For API Schema (HTTP API)
2. Scrape Webpage Contents (HTTP API)
3. Default Data Loader (Document Default Data Loader)
4. Google Gemini Chat Model (Google AI)
- Includes Daniel Grey pack: Slack - Error Alerts, Google Sheets - Audit Log, Wait - Rate Limit, Set - Audit Trail (all wired).

How it works

You run it manually from the n8n editor → Get All Research, All Research Done?, Get All Extract, ending in All Generate Done?.

Setup

1. Open danielgrey.shop/app/templates/dg-0039 → Copy JSON → n8n → Import from Clipboard (or Push to n8n)
2. Connect credentials: Google Sheets, Slack, Google AI, Google Drive
3. Run once manually to verify each branch — it imports clean and goes green first try — then a 10-minute review and activate.

Requirements

- n8n 1.50.0 or later
- Credentials for Google Sheets, Slack, Google AI, Google Drive
- One-time $129 — yours forever, Pro unlocks it too.

Customising

- Tune the logic inside Merge Lists — thresholds and weights are plain code with comments.
- Adjust the branch condition in Has Results? to match your own cutoff.
