Pre-trade risk check for AI agents trading crypto: live orderbook slippage at YOUR size, side-aware funding carry, open-interest crowding, and optional contract security — composed into a single ok/caution/avoid verdict with per-factor reasons and raw data embedded. Answers 'is this trade sane?' before trading, not after. Replaces four API integrations plus the judgment layer.

Buyer-side trust oracle for the x402 marketplace: 'I need X, budget $Y — which tool is real?' Sweeps the WHOLE catalog across many queries, collapses sybil/factory clusters (one wallet stamping many fake-distinct listings), ranks the genuinely-used survivors by unique-payer usage, and returns one vetted pick with a ready-to-pay challenge. The credit-bureau check an agent can't do in a single query.

A stateful, multi-chain spending session for AI agents. One session enforces a hard USDC budget cap across every tool call, with a verifiable receipt and running ledger for each payment — not a one-shot budget check, but persistent spend governance with a full audit trail. The gateway enforces the cap for the paying wallet on Stacks and Base. USDC on Base (standard x402) or Stellar (via the AgentPay SDK); sBTC on Stacks (any Stacks x402 client).
