Community Listening — Social & Forum Signals 👂
foXLabs web & community series: GitHub trending · Hacker News · Wikipedia companies
🎉 Turn community chatter into clean, structured signals — no login, no API key, one row per mention, with the source, author, text, sentiment and links. Built for brand, product and market-research teams.
🔍 What is the Community Listening — and when should you use it?
Give this actor keywords, brands or topics and it returns matching mentions from public community and forum discussions — as clean, deduplicated rows you can filter, export or feed to an AI agent. Every run reads the source live.
Use it when you need: what communities say about a brand or topic; sentiment over time; or a feed of relevant mentions.
Use something else when: you need private analytics — this reads public community discussions only.
🤖 Use with AI agents
Already on the Apify MCP server? Ask for this Actor by name: foxlabs/community-listening.
Your agent can pay for its own runs. This Actor is pay-per-event with agentic payments, so an agent can discover it, run it and settle the bill over x402 (USDC on Base) or Skyfire — no Apify account or API token of its own. Billing is the same either way: per delivered record, never for errors.
Otherwise paste this into Claude, ChatGPT, Cursor or any MCP-enabled assistant:
I want to pull topic company records using the Apify Actor `foxlabs/community-listening`.Input: `query`, `sources`, `datePreset`, `sortBy` and more — see the Input table below. `maxResults` caps how many results are returned.Start with: {"query":"supabase","maxResults":500}Ask me what to look up, run the Actor, then summarise the rows as a table.
The machine-readable API, MCP config and OpenAPI definition live at apify.com/foxlabs/community-listening.md.
📋 Overview
Everything you need to turn public community and forum discussions into clean, structured data — in one actor, with no login, cookies or API key.
Why teams pick this actor:
- ✅ Whole feed, one call — name or ID in, matching mentions out.

- 🔗 Stable identifiers — every row carries the source's own IDs, ready to join across runs and to other Fox Labs actors.
- 💰 Per-row pricing — a minimal price per delivered row, no subscription.
- 🤖 Agent-ready — MCP + x402 agentic payments.
✨ Features
- 🔍 Name or ID lookup — relevance-ranked name search or exact registry-ID lookup.
- 🏢 Full entity profile — status, legal form, formation date, address and the registry’s own contact fields.
- 🧹 Clean schema — deduplicated camelCase rows, ready for CSV/Excel/JSON.

📥 Input
{"query":"supabase","maxResults":500}
| Field | Type | Description |
|---|---|---|
query | string | Required. The brand, product, competitor or topic to track — e.g. "supabase", "clickhouse", "self-hosted". Used as the search phrase on Stack Exchange and Lemmy, and as… |
sources | array | Which communities to listen to. Every source returns rows in the same shape, tagged with source, so you can filter afterwards. |
datePreset | string | How far back to look. Default is all time WITH newest-first sorting, which gives you the most recent mentions without hiding a thin week — Stack Overflow… |
sortBy | string | Newest first for monitoring, most-voted for the discussions that mattered, activity for threads still moving. |
stackExchangeSites | array | Which sites in the Stack Exchange network to search — e.g. ["stackoverflow", "serverfault", "dba", "security"]. Each site is searched separately. Leave empty for… |
lemmyInstance | string | Which Lemmy server to search. Defaults to lemmy.world, the largest general instance; use a niche instance to target its communities. |
mastodonInstance | string | Which Mastodon server's hashtag timeline to read. Defaults to mastodon.social; instances federate, so a large one sees most public posts. |
mastodonHashtags | array | Hashtags to follow, without the #. Leave empty to use the search term itself. Note: Mastodon's full-text search needs an account token, so this Actor reads… |
stackExchangeKey | string | Without a key Stack Exchange allows ~300 requests/day per IP; a free key raises it to 10,000/day and lets big sweeps run faster. Get one at stackapps.com — no… |
maxResults | integer | Hard cap on mentions returned across all sources. The budget is shared evenly between the sources you selected — and whatever one source doesn't use passes to… |
📤 Output

❓ FAQ
Do I need an account, login or API key? No. This reads public community and forum discussions.
What do I search by? Keywords, brands or topics.
How current is the data? Every run queries the source live, so results are as fresh as the registry.
Which communities? Public forums and community discussions the query matches; each row carries the source, author, text and sentiment.
Can I export to CSV / Excel / JSON? Yes — directly from the Apify dataset.
🐛 Troubleshooting
- Fewer rows than expected — raise
maxResults, or refine the input. - A name returns an unexpected entity — it matched a similar registered name; search the exact registry ID.
- No rows for a name — try the entity’s exact legal name or its registry ID.
⚖️ Is it legal to scrape this data?
This actor reads publicly available community and forum discussions. Results can still contain personal data (e.g. a person’s name); personal data is protected by the GDPR and similar laws, so only process it with a legitimate basis. See Apify’s blog post on the legality of web scraping.

Changelog
0.1.14 — 2026-09-20 — README examples corrected against the real input schema
- The README's code examples did not match this Actor. They used
queriesandmaxResultsPerQuery— keys that do not exist in this Actor's input schema — with a placeholder value, and the input table listed those same phantom fields. Anyone who copied the AI-agent, cURL, JavaScript or Python example got a failing run. Every example now uses the real schema and matches the Console prefill:{"query":"supabase","maxResults":500} - The input table is regenerated from
input_schema.json, so it lists the fields the Actor actually accepts. - Removed claims carried over from the same generator template where present: "formation / status monitoring", "a canonical registry record for KYB and due diligence", "every row carries
query", andindustrydescribed as a NACE code. - No code, output field or pricing change.
0.1 — 2026-09-07
- Enabled AI-agent payments (x402) + rebuilt the README to the full standard (What-is / when, AI-agents + x402 agentic payments + MCP, Overview, Features, Use cases, Integration, FAQ, Troubleshooting, Support & contact).
