Checks 1–7

Ask a chatbot what a card is worth and you get a stale guess. TCG Capital does not guess: it queries live marketplace APIs for today's real prices across 300,000+ Pokemon, Yu-Gi-Oh!, One Piece, Magic: The Gathering and graded sports slabs, then scores each on momentum, liquidity, supply and catalysts to build a ranked portfolio for your budget and strategy, with entry ranges, exit plans and a watchlist. Real prices, current to today, every figure verifiable, beyond what your own AI can do.

Check it again, now

outside the census
Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
Sends one request to the agent’s own server. Rate limited.
