Refresh the report for https://kalshi.com/markets/kxbtcy/btc-price-range-eoy/kxbtcy-27jan0100

Prediction Markets Mode

When Prediction Markets Agent is selected, the node exposes three modes:

• Default Report: Uses octagon-prediction-markets-agent, which checks the cache first and refreshes only on cache miss
• Cache Search: Uses octagon-prediction-markets-agent:cache, which returns cache metadata as JSON text
• Refresh Report: Uses octagon-prediction-markets-agent:refresh, which always generates a new report

Prediction markets requests must include a Kalshi market URL in the query text.

Cache Search responses keep the raw response in analysis and also expose parsed JSON in cacheData when available.

Refresh requests may require a paid plan and premium credits, based on your Octagon subscription.

Output Format

The node returns a JSON object with the following structure:

{
	"agent": "octagon-agent",
	"model": "octagon-agent",
	"query": "Tell me about Apple's latest earnings",
	"analysis": "Apple reported strong Q4 2023 results with revenue of $89.5 billion...",
	"sources": [
		{
			"order": 1,
			"name": "Apple Inc. (10-Q) - 2023-Q4, Page: 10",
			"url": "https://octagon-sec-filings.s3.amazonaws.com/..."
		}
	],
	"metadata": {
		"apiType": "responses",
		"timestamp": "2024-01-15T10:30:00.000Z"
	},
	"usage": {
		"prompt_tokens": 150,
		"completion_tokens": 800,
		"total_tokens": 950
	}
}

Best Practices

1. 🎯 Use the Router: Start with "Octagon Agent (Router)" - it automatically selects the best specialized agent
2. 📝 Be Specific: The more specific your query, the more accurate the response
3. 🔄 One Task Per Query: Focus each query on a single analytical task for best results
4. 📅 Provide Context: Include relevant context like time periods, specific metrics, or companies
5. 🔗 Follow Citations: Always check the source citations for verification

Error Handling

The node includes comprehensive error handling:

• 🔑 Authentication Errors: Invalid API keys, expired tokens
• 🌐 Network Errors: Connection issues, timeouts, rate limits
• 📝 Query Errors: Malformed or empty queries
• 🤖 Agent Errors: Agent-specific errors or limitations

By default, the node throws standard n8n errors and the execution fails in the n8n UI. HTTP and API failures are surfaced through n8n's normal error handling so you can inspect the full request context.

If you enable Continue On Fail on the node, the node returns a structured error row instead of throwing:

{
	"error": true,
	"message": "Authentication failed. Please check your API key.",
	"query": "Your original query",
	"agent": "octagon-agent",
	"model": "octagon-agent",
	"timestamp": "2024-01-15T10:30:00.000Z"
}

This lets workflows branch on failed items while preserving n8n-standard behavior when Continue On Fail is disabled.

Release Process

Verified n8n community-node releases must be published from GitHub Actions with npm provenance.

To publish a new version:

1. Merge the release changes to main.
2. Ensure npm Trusted Publisher is configured for repository OctagonAI/n8n-nodes-octagon and workflow filename publish.yml.
3. Bump the package version in the repository.
4. Push the matching version tag to GitHub.
5. Let .github/workflows/publish.yml publish the package with provenance.

Do not publish verified releases with a local npm publish command.

Troubleshooting

Common Issues

1. Node not appearing: Restart n8n after installation
2. Icon not loading: Clear browser cache
3. Authentication errors: Verify API key in credentials
4. Rate limiting: Check your Octagon plan limits
