# Firecrawl
Firecrawl helps AI agents search, scrape, and interact with the web.
## Features
- Search: Find information across the web
- Scrape: Clean data from any page
- Interact: Click, navigate, and operate pages
- Agent: Autonomous data gathering
Scrape a page, then interact with it using AI prompts or code.
from firecrawl import Firecrawl
app = Firecrawl(api_key="fc-YOUR_API_KEY")
result = app.scrape("https://amazon.com")
scrape_id = result.metadata.scrape_id
app.interact(scrape_id, prompt="Search for 'mechanical keyboard'")
app.interact(scrape_id, prompt="Click the first result")
Node.js
import { Firecrawl } from 'firecrawl';
const app = new Firecrawl({apiKey: "fc-YOUR_API_KEY"});
const result = await app.scrape("https://amazon.com");
await app.interact(result.metadata.scrapeId, {
prompt: "Search for 'mechanical keyboard'"
});
await app.interact(result.metadata.scrapeId, {
prompt: "Click the first result"
});
cURL
# 1. Scrape the page
curl -X POST 'https://api.firecrawl.dev/v2/scrape' \
-H 'Authorization: Bearer fc-YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"url": "https://amazon.com"}'
# 2. Interact with the page (use scrapeId from step 1)
curl -X POST 'https://api.firecrawl.dev/v2/scrape/SCRAPE_ID/interact' \
-H 'Authorization: Bearer fc-YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"prompt": "Search for mechanical keyboard"}'
CLI
firecrawl scrape https://amazon.com
firecrawl interact exec --prompt "Search for 'mechanical keyboard'"
firecrawl interact exec --prompt "Click the first result"
Output:
{
"success": true,
"output": "Keyboard available at $100",

}
Connect Firecrawl to any AI agent or MCP client in minutes.
Give your agent easy access to real-time web data with one command.
npx -y firecrawl-cli@latest init --all --browser
Restart your agent after installing. Works with Claude Code, Antigravity, OpenCode, and more.
Connect any MCP-compatible client to the web in seconds.

The easiest way to get data from the web. Describe what you need, and our AI agent searches, navigates, and retrieves it. No URLs required.
Agent is the evolution of our /extract endpoint: faster, more reliable, and doesn't require you to know the URLs upfront.
curl -X POST 'https://api.firecrawl.dev/v2/agent' \
-H 'Authorization: Bearer fc-YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"prompt": "Find the pricing plans for Notion"
}'
Response:
{
"success": true,
"data": {
"result": "Notion offers the following pricing plans:\n\n1. Free - $0/month...\n2. Plus - $10/seat/month...\n3. Business - $18/seat/month...",
"sources": ["https://www.notion.so/pricing"]
}
}
Use a schema to get structured data:
from firecrawl import Firecrawl
from pydantic import BaseModel, Field
from typing import List, Optional
app = Firecrawl(api_key="fc-YOUR_API_KEY")
class Founder(BaseModel):
name: str = Field(description="Full name of the founder")
role: Optional[str] = Field(None, description="Role or position")
class FoundersSchema(BaseModel):
founders: List[Founder] = Field(description="List of founders")
result = app.agent(
prompt="Find the founders of Firecrawl",
schema=FoundersSchema
)
print(result.data)
{
"founders": [
{"name": "Eric Ciarla", "role": "Co-founder"},
{"name": "Nicolas Camara", "role": "Co-founder"},
{"name": "Caleb Peffer", "role": "Co-founder"}
]
}
Focus the agent on specific pages:
result = app.agent(
urls=["https://docs.firecrawl.dev", "https://firecrawl.dev/pricing"],
prompt="Compare the features and pricing information"
)
Set how much reasoning the agent spends on the task:
| Effort | Best For |
|---|---|
low | Simple lookups on one site |
medium | Multi-step tasks on a few pages |
high | Deep research, complex navigation, critical data |
result = app.agent(
prompt="Compare enterprise features across Firecrawl, Apify, and ScrapingBee",
effort="high"
)
Every effort level runs the spark-2 model. Effort changes the reasoning
budget, not the model.
Every agent run executes on spark-2, the default, so you don't need to set
model. The retired spark-1-pro and spark-1-mini names are still accepted
for backwards compatibility, but they are deprecated and run spark-2.
Learn more about Spark models in our Agent documentation.
Crawl an entire website and get content from all pages.
curl -X POST 'https://api.firecrawl.dev/v2/crawl' \

"id": "123-456-789",
"url": "https://api.firecrawl.dev/v2/crawl/123-456-789"

Find specific URLs within a site:
from firecrawl import Firecrawl
app = Firecrawl(api_key="fc-YOUR_API_KEY")
result = app.map("https://firecrawl.dev", search="pricing")
# Returns URLs ordered by relevance to "pricing"
Scrape multiple URLs at once:
from firecrawl import Firecrawl
app = Firecrawl(api_key="fc-YOUR_API_KEY")
job = app.batch_scrape([
"https://firecrawl.dev",
"https://docs.firecrawl.dev",
"https://firecrawl.dev/pricing"
], formats=["markdown"])
for doc in job.data:
print(doc.metadata.source_url)
Our SDKs provide a convenient way to use all Firecrawl features and automatically handle polling for async operations.
Install the SDK:
pip install firecrawl
from firecrawl import Firecrawl
app = Firecrawl(api_key="fc-YOUR_API_KEY")
# Scrape a single URL
doc = app.scrape("https://firecrawl.dev", formats=["markdown"])
print(doc.markdown)
# Use the Agent for autonomous data gathering
result = app.agent(prompt="Find the founders of Stripe")
print(result.data)
# Crawl a website (automatically waits for completion)
docs = app.crawl("https://docs.firecrawl.dev", limit=50)
for doc in docs.data:
print(doc.metadata.source_url, doc.markdown[:100])
# Search the web
results = app.search("best AI data tools 2024", limit=10)
print(results)
Install the SDK:
npm install firecrawl
import { Firecrawl } from 'firecrawl';
const app = new Firecrawl({ apiKey: 'fc-YOUR_API_KEY' });
// Scrape a single URL
const doc = await app.scrape('https://firecrawl.dev', { formats: ['markdown'] });
console.log(doc.markdown);
// Use the Agent for autonomous data gathering
const result = await app.agent({ prompt: 'Find the founders of Stripe' });
console.log(result.data);
// Crawl a website (automatically waits for completion)
const docs = await app.crawl('https://docs.firecrawl.dev', { limit: 50 });
docs.data.forEach(doc => {
console.log(doc.metadata.sourceURL, doc.markdown.substring(0, 100));
});
// Search the web
const results = await app.search('best AI data tools 2024', { limit: 10 });
