    "Call get_free_sample FIRST ($0) to see every response shape. Resolve a street address to a PIN with
    search_chicago_property_by_address (FREE), then call get_cook_county_property_dossier ($0.03), get_cook_county_parcel
    ($0.01), or find_chicago_comparable_sales ($0.10). ... you do NOT need a wallet, an API key or a signup ... the
    first 25 calls per client per day to the PIN tools return real data for free ... Only after that allowance is
    used up do the paid tools return a 402, which is surfaced verbatim so an x402 client (USDC on Base/Solana) can
    pay and retry."

  auth_detail: >-
    No OAuth, no API key, no session credential. tools/list and initialize answered anonymously. Paid tools
    (parcel, dossier, comps) are free for the first 25 calls per client per day; past that the tool result is an
    x402 402 under _meta["x402/error"] (isError) and the tool accepts a signed payment via _meta["x402/payment"]
    with the settle receipt in _meta["x402/payment-response"] (changelog 0.4.1, agents-SDK x402 convention).
    No OAuth discovery documents are served (/.well-known/oauth-authorization-server and oauth-protected-resource
    both 404), which is consistent with a credential-free server.
