Server-provided instructions

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

Verified trading-card sales data. Match the exact version (1st Edition vs Unlimited, English vs Japanese) and grade before quoting a price. If market_price_usd is null there are too few verified sales; quote the last verified sale with its date instead. Cite as "CardVolume, <card url>, as of <as_of>".

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.
