Fetch a URL and convert to clean markdown for LLM consumption.

Content conversion (automatic by Content-Type):

• HTML → clean markdown (boilerplate removed, links preserved)

• PDF → markdown with headings and table detection (requires pdf feature)

• JSON/plain text → passthrough

• SPA data auto-extracted (NEXT_DATA, NUXT, APOLLO_STATE, etc.)

Network features:

• HTTP/2 multiplexing, HTTP/3 (QUIC) with 0-RTT

• TLS 1.3, Brotli/Zstd/Gzip decompression

• Realistic browser fingerprints (Chrome/Firefox/Safari)

• Browser cookie injection (Brave/Chrome/Firefox/Safari)

Diff mode (diff: true):

• Compares current content against the previous snapshot for this URL

• Returns only the changed sections (token-efficient for monitoring tasks)

• First fetch caches the page; subsequent fetches return semantic diffs

• Unchanged content returns a 5-token confirmation instead of full body

Focus mode (focus: query):

• Keeps only sections relevant to the query (BM25 scoring)

• Replaces dropped sections with '[N sections omitted]' markers

• Diff markers are always preserved regardless of relevance

Token budget (max_tokens: N):

• Structure-aware truncation preserving headings, code, and tables

• Priority: title > code/tables > headings (30% cap) > body > blockquotes

Returns: Markdown-converted body with timing info (or diff when diff: true).

Fetch multiple URLs in parallel with HTTP/2 multiplexing.

Uses connection pooling and multiplexing for maximum efficiency. All URLs are fetched concurrently.

Returns: Results for each URL with timing.

Submit a web form with smart field extraction.

Fetches a page, parses all forms, extracts hidden fields and CSRF tokens, merges user-provided fields, and submits via POST.

Use for: login forms, search forms, API interactions behind HTML pages.

Returns: Response body (markdown-converted) after form submission.

Auto-login to a website using 1Password credentials.

Detects login form, retrieves credentials from 1Password, fills and submits, handles MFA/2FA with TOTP. Returns the authenticated page content.

Requires: 1Password CLI (op) installed and authenticated.

Returns: Final page content after login (markdown-converted).

Look up credentials in 1Password for a URL.

Searches 1Password for credentials matching the URL/domain. Returns credential info (username, TOTP availability) without exposing password.

Returns: Credential info if found.

Generate realistic browser fingerprints.

Creates browser profiles for Chrome, Firefox, or Safari. Includes User-Agent, Sec-CH-UA headers, Accept-Language, platform info.

Returns: Generated fingerprint profiles.

Run validation tests against real websites.

Tests: HTTP/2, HTTP/3, compression, fingerprinting, TLS 1.3, 1Password.

Returns: Validation results with timing.

Benchmark fetching URLs with timing statistics.

Measures min/avg/max response times over multiple iterations.

Returns: Benchmark results with timing statistics.
