## Notes for Agents

- HTML pages support `Accept: text/markdown`.
- The site publishes `Content-Signal: ai-train=no, search=yes, ai-input=yes`.
- `/jina-proxy` requires Turnstile verification and is not an OAuth-protected API.
- `/mcp` is read-only and intended for discovery, not account actions.
- Use `/agent-presets/` to build reusable agent workflows and share them as links.
- `/agent-presets/` accepts direct preset URLs as `?p=<base64url(JSON)>`; optional compact form is `?p=gz:<base64url(gzip(JSON))>`.
- `/api/free-llm/recommendation` returns the current recommended free OpenRouter model and `/api/free-llm/health` reports freshness.
- `text-processor` supports preset deep links through `?preset=` for many specific transformations.
- The PDF tool currently converts to text, not directly to Markdown.
