Microlink
Extracts structured metadata (title, description, images, video) and captures screenshots from any URL using a headless browser.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Open-source core increases auditability; API key is a single secret with no scope restrictions; SSRF risk when accepting user-supplied URLs.
⚡ Reliability
Best When
You need URL metadata enrichment and optional screenshots with a simple API call and a generous free tier.
Avoid When
You need deep structured data extraction or complex browser automation workflows.
Use Cases
- • Generate rich link previews with title, description, and OG image for any URL in a content agent
- • Take screenshots of web pages for visual archival or change monitoring workflows
- • Extract structured metadata from article URLs to populate knowledge bases automatically
- • Detect video embeds and media content in URLs for media aggregation pipelines
- • Validate that URLs are live and accessible as part of automated link-checking agents
Not For
- • Large-scale bulk web scraping with complex pagination and data extraction
- • Authenticating into and navigating password-protected web applications
- • Real-time streaming or sub-second latency use cases
Interface
Authentication
API key passed as x-api-key header; free tier operates without authentication at lower rate limits.
Pricing
Free tier is rate-limited but functional; no credit card required for free access.
Agent Metadata
Known Gotchas
- ⚠ Rate limit headers must be checked on every response; hitting limits returns 429 with no automatic retry logic
- ⚠ Screenshot feature requires the screenshot=true query parameter; metadata-only calls do not capture screenshots
- ⚠ Some metadata fields (video, audio) may be null even when present on the page due to JS execution limitations
- ⚠ Free tier requests share infrastructure and may have higher latency during peak periods
- ⚠ The data field structure varies by URL type (article vs video vs image); agents must handle optional fields defensively
