+# Firehose
+
+Real-time web data streaming API that monitors web pages and delivers matching content instantly via server-sent events (SSE). Built for competitive intelligence, brand monitoring, and news tracking without polling.
+
+## Capabilities
+
+| Integration | Available | Notes |
+|-------------|-----------|-------|
+| API | ✓ | RESTful endpoints for managing rules + SSE for streaming |
+| MCP | - | Not available |
+| CLI | - | Not available |
+| SDK | - | Native AI agent skill available |
+
+## Authentication
+
+- **Type**: API Key
+- **Currently**: Free beta — no credit card required
+- **Get access**: Sign up at firehose.com
+
+## Core Concepts
+
+**Rules** — Filters that define what content to match. Uses Lucene query syntax.
+
+**Stream** — A server-sent event (SSE) connection that delivers matching content in real-time as it's published on the web.
+
+Instead of polling an endpoint on a schedule, you define rules once and receive a continuous stream of matches as they happen.
+
+## Query Syntax (Lucene)
+
+```
+# Exact phrase
+"your brand name"
+
+# Field-specific
+title:tesla
+domain:reuters.com
+domain:techcrunch.com
+
+# Boolean operators
+"Series A" AND (SaaS OR software)
+competitor OR "competitor name" NOT "your company"
+
+# Wildcard
+market* AND funding
+
+# Language filter
+language:en
+
+# Date range
+publish_time:[2026-01-01 TO 2026-03-18]
+
+# ML-classified categories
+category:finance
+category:technology
+```
+
+## Common Agent Operations
+
+### Create a monitoring rule
+
+```bash
+POST https://api.firehose.com/rules
+
+{
+  "query": "\"your brand name\" OR \"your product name\"",
+  "label": "brand-mentions"
+}
+```
+
+### List active rules
+
+```bash
+GET https://api.firehose.com/rules
+```
+
+### Delete a rule
+
+```bash
+DELETE https://api.firehose.com/rules/{rule_id}
+```
+
+### Connect to the stream
+
+```bash
+GET https://api.firehose.com/stream
+Authorization: Bearer {api_key}
+
+# Returns server-sent events:
+# data: {"url": "...", "title": "...", "publish_time": "...", "matched_rule": "..."}
+```
+
+### Example: Node.js stream consumer
+
+```javascript
+import EventSource from 'eventsource';
+
+const stream = new EventSource('https://api.firehose.com/stream', {
+  headers: { Authorization: `Bearer ${process.env.FIREHOSE_API_KEY}` }
+});
+
+stream.onmessage = (event) => {
+  const item = JSON.parse(event.data);
+  console.log(`[${item.matched_rule}] ${item.title} — ${item.url}`);
+};
+```
+
+## Use Cases for Marketing
+
+### Competitive intelligence
+Monitor competitors' press coverage, product announcements, and funding news in real-time.
+
+```
+query: "CompetitorName" AND (launch OR funding OR "product update" OR partnership)
+```
+
+### Brand monitoring
+Track mentions of your brand across news and web content.
+
+```
+query: "YourBrand" OR "YourProductName" NOT site:yourdomain.com
+```
+
+### Category / market news
+Stay current on your market without manually checking sources.
+
+```
+query: category:technology AND ("no-code" OR "low-code") AND funding
+domain:techcrunch.com OR domain:venturebeat.com
+```
+
+### Lead trigger monitoring
+Track signals that indicate a prospect is ready to buy (hiring, funding, tool mentions).
+
+```
+query: ("hiring" OR "we're growing") AND "RevOps" AND (HubSpot OR Salesforce)
+```
+
+### PR and link building
+Get alerted when publications cover topics in your space, enabling timely outreach.
+
+```
+query: "best [category] tools" OR "top [category] software" AND publish_time:[now-7d TO now]
+```
+
+## When to Use
+
+- Real-time competitive intelligence (faster than Google Alerts)
+- Brand mention monitoring across news and web
+- Market signal tracking for sales prospecting
+- Automated content curation pipelines
+- Trigger-based workflows (new mention → Slack alert, CRM update, etc.)
