Resolve a US stock ticker (e.g. AAPL) to its SEC CIK number, the primitive every other EDGAR call needs. Returns CIK in both zero-padded (0000320193) and integer form, plus the registered company name. Backed by SEC's company_tickers.json (public domain). ?ticker=AAPL

Validate an email address: syntax check plus live MX record lookup on the domain (deliverability signal, not a guarantee).

Validate, pretty-print, or minify JSON. Returns parse errors with position when invalid.

Extract a value from JSON by dot/bracket path, e.g. "items[2].name".

Convert a JSON array of objects to CSV. Nested objects are flattened to dot-path columns.

Convert JSON to YAML.

Decode a JWT without verification: header, payload, expiry status, and time remaining. (Decoding only — signatures are NOT verified.)

Run a regular expression against text. Returns up to 100 matches with index and capture groups. Pattern ≤ 200 chars, text ≤ 10KB.

Render a page in a real headless Chromium browser (JavaScript executed), then extract the main content as clean markdown. Use this for SPAs and JS-heavy sites where plain fetching returns an empty shell.

Fetch a site's robots.txt and answer: may this user-agent crawl this path? Returns the matched rule and all declared sitemaps.

Screenshot any public URL in headless Chromium. Returns a PNG image. Query params: ?url=https://…&fullPage=true (optional).
