Fetch a PDF by URL and extract its text as Markdown, with page count and word count. Lets AI agents read PDF documents, reports and papers. (Text-based PDFs; scanned/image-only PDFs are not OCR'd.)

On-chain native + ERC-20 token balances for any EVM address across Ethereum, Base, Arbitrum, Optimism and Polygon. For wallet-tracking and DeFi agents.

Resolve an ENS name to an address, or reverse-resolve an address to its ENS name (Ethereum mainnet). Identity lookups for crypto agents.

Turn any web page into clean, LLM-ready Markdown. Fetches the URL, isolates the main article with Mozilla Readability (stripping nav, ads and boilerplate), and returns tidy Markdown with the page title and word count — built for AI agents, RAG pipelines, web scraping and content ingestion.

ERC-20 token metadata (name, symbol, decimals, total supply) for any token contract across major EVM chains. On-chain reference data for agents.

Real-time crypto spot price for any asset (BTC, ETH, SOL, …) in USD or another currency. Live market data feed for AI trading and finance agents.

Current gas price (gwei) on Ethereum, Base, Arbitrum, Optimism or Polygon. Lets agents time and price on-chain transactions.

Extract structured metadata from any web page: title, description, author, published date, language, OpenGraph image, canonical URL, favicon and estimated reading time. Lightweight enrichment for AI agents and link indexing.

Generate a QR code (PNG data-URI or SVG) for any text or URL. Simple, instant utility endpoint.

Convert an RSS 2.0 or Atom feed URL into clean, normalized JSON (title, link, published date, summary per item). For agents monitoring news, blogs and content sources.

Generate a compact link-preview card (title, description, image, site name) from a URL using OpenGraph/Twitter tags — for chat unfurls, social previews and agent link summaries.
