      annotations: {"readOnlyHint":true}; The name "request_brief" says "request": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Order a custom research brief on your topic ($1.50 USDC per brief). Topics must be in our lanes: stablecoins, RWA/tokenization, DeFi, the AI agent economy, crypto markets. The brief is researched on demand (up to ~60 min); use check_brief_status to poll for it (polling is free). First call (no payment_signature) returns the payment challenge; pay the exact USDC on Solana, then call again with payment_signature.

    Annotations the server declares

    • readOnlyHint: true
  • verify_claimVerify a factual crypto-markets claim against a sourced, dated claims cache: confirmed / refuted / unverifiable, with evidence and sources ($0.10 USDC per call).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
