Get OAuth2 config by service name using AI agent

# Finds OAuth2 config by service name and returns JSON with confidence score

This workflow automatically retrieves OAuth2 configuration parameters — service name, audience, authorization and token URIs — from just the service name using an AI agent. Designed for developers and technical specialists who need fast, accurate integration data without manually searching documentation.

## Who it´s for
- Developers integrating third-party APIs with OAuth2
- DevOps engineers setting up automated access to services
- Technical staff seeking a quick way to retrieve OAuth parameters
- Teams using n8n for complex API integrations

## What the automation does
- Accepts a service name (e.g., "Jira", "Google", "Sage") as input
- Triggers an AI agent powered by LangChain and Llama 3.3 via OpenRouter
- Analyzes official documentation and common OAuth2 patterns
- Extracts key parameters: service name, audience, authorization and token URIs
- Adds explanations and confidence scoring
- Normalizes output into a consistent JSON structure for downstream use

## What´s included
- Ready-to-use n8n workflow
- Trigger and handler logic based on LangChain
- Integration with OpenRouter and support for Llama 3.3 models
- Support for services: Atlassian API, Google API, Sage API, SAP API
- Basic text instructions for setup and adaptation

## Requirements for setup
- n8n instance (self-hosted or cloud)
- OpenRouter API key
- Access to target service documentation (Atlassian, Google, Sage, SAP, etc.)
- Basic understanding of JSON and LLM usage in low-code environments

## Benefits and outcomes
- Saves time searching OAuth endpoints in docs
- Reduces errors from manual copying of URIs
- Consistent JSON output format for downstream automation
- Confidence scores help assess reliability of results
- Can be embedded into larger API client setup pipelines
- Handles ambiguous or partial inputs (e.g., "SAP" → most likely variant)
