Hand it to your AI agent
Copy this prompt into Claude Code, Cursor, Codex or any coding agent. It tells the agent where the docs are and how to use your API key.
Use the Lovely Router data tool "List Facebook comments" (id `facebook-comments`, Facebook) to get data for me. It returns JSON.
- Docs (read first): https://lovelyrouter.com/docs/tools/run.md and https://lovelyrouter.com/docs/api/tools.md
- Input fields and price: GET https://lovelyrouter.com/v1/tools/facebook-comments (public, no key needed). Price: $0.00062 / comment + $0.0015 / call.
- Run: POST https://lovelyrouter.com/v1/tools/facebook-comments/run with a body like `{"input":{"startUrls":[{"url":"https://www.facebook.com/humansofnewyork/posts/pfbid0BbKbkisExKGSKuhee9a7i86RwRuMKFC8NSkKStB7CsM3uXJuAAfZLrkcJMXxhH4Yl"}],"resultsLimit":3},"max_results":10}`. A 200 has the finished run with `items`; a 202 means it is still running, so poll the `poll` path until `status` is `succeeded`, `failed`, `timed_out` or `stopped`.
- Only delivered results are billed. Keep max_results small on the first run, check the output, then scale up (up to 500 per run).
- If you support MCP, you can instead connect the server https://lovelyrouter.com/mcp (Streamable HTTP, same key; https://lovelyrouter.com/docs/tools/mcp.md) and use suggest_tools, get_tool and run_tool with tool "facebook-comments".
- Auth: read my API key from the LOVELY_API_KEY environment variable and send it as `Authorization: Bearer $LOVELY_API_KEY`. Never print or commit the key. If it is not set, ask me to create one at https://lovelyrouter.com/app/keys.
- Billing is prepaid: every call is charged to my balance, so test with a small request before running anything large.
- Every docs page is plain Markdown; the full index is https://lovelyrouter.com/llms.txt.

onlyCommentsNewerThanstringOptional cut-off. A date (2026-01-31 or a full timestamp like 2026-01-31T18:00:00Z), a span (3 days, 2 weeks ago, 24h, 7d), or yesterday / today. Comments older than this are dropped and never charged. A value it cannot read stops the run before it reads a comment, with a free note saying which forms work. There is no add-on fee for using it.

Frequently asked questions
How much does the List Facebook comments API cost?
$0.00062 / comment + $0.0015 / call. 1,000 results, fetched in runs of up to 500, cost $0.623. There is no subscription: you pay from a prepaid balance.
Is this a Facebook comments scraper?
Yes. If you searched for a Facebook comments scraper, a Facebook post comments API or a Facebook comment extractor, this is it: Comments on public Facebook posts or reels by URL.
How many results does one run return?
20 by default and up to 500 per run. Set max_results to cap a run: you are billed only for the results it delivers.
Do I need a Facebook account or API key?
No. You call the tool with your Lovely Router API key and get JSON back. There is nothing to set up on Facebook.
Can an AI agent use this tool?
Yes. Connect Claude Code, Cursor or any MCP client to the Lovely Router MCP server: the agent finds the tool with suggest_tools and runs it with run_tool and the id facebook-comments.
What happens if a run fails?
A run that fails or is stopped pays only for the results it delivered, with no call fee. The most a run can cost is held when it starts and the rest is released when it settles.
