Get structured metadata for any public web page in one call: title, meta description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD schema types, language and the heading outline. Use it to build link previews and social cards, classify or dedupe URLs, and run SEO and AI-readability audits - far cheaper than fetching and parsing the whole page.

Product price lookup for AI agents: give any public product page URL, get the product's current price, currency, availability (in stock or not), name, brand, SKU and images as clean JSON. The page is rendered in a real browser, so JavaScript stores work, and the store's own schema.org product data is read first. For price checks, price monitoring and comparing stores before you buy.

Verify a package: does it exist, is it deprecated or yanked, and does it have known vulnerabilities? Checked against the npm/PyPI/crates.io registry plus OSV.dev advisories.

ChainQuery Bitcoin Intelligence: independent Bitcoin-native on-chain data over x402, no API key. Live mempool fee-pressure signal (state low/moderate/high/severe + score in sat/vB).

Pre-registered overnight continuation read for the Robinhood-tradable crypto universe: the top-5 session-momentum coins into the 20:00 UTC signal, the BTC 200-day regime gate, and the study receipts. The ranking beat its random null at every fee tier in the cold study; at Robinhood retail fees the studied trade was REFUTED — a state read with its refutation attached, not advice. ~15-min refresh, 24/7.

One original constraint card in the tradition of lateral-thinking decks: a short instruction, reversal or question you can apply to whatever is stuck, written fresh by a model at high temperature on every call. The cards are ours, never a card from any published deck. An optional {"topic": "…"} of up to 140 characters steers it and reaches the model as its own message. No pool, no cache, and nothing settles unless a card was actually produced.
