Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Paid web tools: web and paper search, page reading, cited answers, summaries and JSON extraction, PDFs and PDF text, OCR, SEC filings, sanctions screening, counterparty, company, domain, email, phone and SEO checks, URL status and page-change checks, QR codes, weather and IP lookup. Each call costs $0.0099 to $0.2 in USDC over x402 (each tool's description gives its price): call a tool, get the payment terms, pay, call again. Calls that fail are not charged. quantagentshop_quote is free: it gives any tool's terms and checks its arguments first. Put a random _meta idempotency-key beside the payment to get the result again after a lost reply, by resending the same payment, key and arguments within 10 minutes. Invited pilot integrators put their pilot key in _meta pilot-key instead of a payment.

Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Free, no payment. Send the name of any paid tool here, and optionally the arguments you plan to send; returns its price, network and payTo address (the same terms its 402 gives) and whether the arguments are valid, with the errors if not. Nothing runs upstream. With a pilot key in _meta pilot-key, also says whether the key is valid for that tool and how much of today's allowance (in list price) is left.
