For AI Agents and Automated Discovery

#

All three APIs are listed in the site's standards-compliant catalog and are markdown-negotiable from any tigzig.com URL. An agent doesn't need to scrape HTML to learn the API surface - it can fetch one well-known JSON file.

Discovery endpoints

Markdown content negotiation

Send Accept: text/markdown on any tigzig.com page and the response is the structured markdown for that page, not the empty React SPA shell. Useful for agents that follow links from other pages without first knowing the llms.txt URL. 

curl -H "Accept: text/markdown" https://tigzig.com/

Per-API discovery (well-known)

MCP endpoints (for AI agent integration)

  • api.tigzig.com/tremor/v1/mcp/http - TREMOR macro indicators via Streamable HTTP
  • api.tigzig.com/tremor/v1/mcp/sse - TREMOR macro indicators via SSE (legacy)
  • Full MCP server directory: tigzig.com/.well-known/mcp/servers.json
