Firecrawl API
Firecrawl converts any URL or website into clean, LLM-ready markdown. It handles JavaScript-rendered pages, bypasses common anti-scraping measures, converts PDFs and other formats, and returns structured content that agents can immediately use without HTML parsing. Includes crawl (multi-page), scrape (single-page), extract (structured data with schema), and search endpoints.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Simple API key auth. SOC2 in progress. Web scraping service — agents should be aware that scraped content may contain untrusted data. Rate limits enforced to prevent abuse.
⚡ Reliability
Best When
An agent needs to read web content that would otherwise be unstructured HTML — Firecrawl produces clean Markdown that LLMs understand directly.
Avoid When
You just need to fetch a simple static page — a plain HTTP GET is cheaper and faster.
Use Cases
- • Agent needs to read web content and convert it to usable text for reasoning
- • Building research agents that crawl websites and extract structured information
- • Converting documentation sites to Markdown for RAG knowledge bases
- • Extracting structured data from web pages using JSON schema
- • Monitoring web pages for changes over time
Not For
- • High-volume scraping at scale (rate limits apply, costs add up)
- • Sites that require authentication or active sessions (basic account-gated content)
- • Real-time data where millisecond latency matters
Interface
Authentication
Bearer token in Authorization header. Single API key per account. Keys have no scopes — full account access. Self-hosted version has no auth by default.
Pricing
Can also self-host the open source version with no API costs. Credits consumed per page — crawl jobs use 1 credit per page discovered. Very cost-effective for moderate use.
Agent Metadata
Known Gotchas
- ⚠ Async crawl jobs return a jobId — agents must poll /crawl/{id} or use webhooks to get results; don't wait inline
- ⚠ Credits deplete quickly on crawl jobs that discover many pages — set maxDepth and limit parameters
- ⚠ Some sites block Firecrawl's crawler just like any scraper — no guarantee every URL will succeed
- ⚠ Free tier 5 req/min limit is easy to hit in agent loops — implement exponential backoff
- ⚠ Self-hosted version doesn't support all features (some JS rendering is cloud-only)
- ⚠ The extract endpoint uses LLM internally, so latency is higher and results may vary
