Reads that declared peg alongside the issuance profile (supply, cap) and control powers (seize/freeze/pause/uncapped-mint) — a one-call 'what is this stablecoin and who controls it' for agents settling in B20 stablecoins. The currency code is the issuer's claim, not attested backing.

Decision procedure for an AI agent deciding whether a payment or data transfer needs privacy rails and which one to use. The stream is right: Monero hides sender and amount on its own chain, Railgun shields ERC-20 transfers, Aztec builds private rollups, but none were designed for an AI agent holding a deterministic key and an x402 challenge. Ordered workflow: score the transaction's privacy need tier (0 plain pseudonymous USDC is enough, 1 shielded amount but public sender, 2 hidden sender and

Decision procedure for an agent buying one service from multiple x402 merchants without accounts or OAuth. Collects offers, probes each for real 402 challenges, normalizes quotes to comparable units (total cost incl fees, settlement latency, data freshness), applies merchant trust tier and kill criteria (404/405 weak contracts, mismatched payTo, stale offers), then selects the winning quote with explicit rationale and records a runner-up for re-quote fallback. Returns a ranked quote table with

Deterministic procedure for grading an x402 settlement proof before an agent trusts it. Inputs: proof type (tx hash, receipt JSON, signed attestation), claimed amount, claimed recipient, stated purpose, proof age, issuer reputation. Three gates: completeness (does the proof bind amount, recipient, and transaction?), opacity (which facts are asserted versus left unverifiable?), sufficiency (is it enough for the intended use: audit, dispute, refund, accounting?). Thresholds define when a proof is

Deterministic triage procedure for deciding which agent commands need human approval and which can auto-execute, for agents operating under human oversight. Given a command, this procedure scores six threat markers: (1) fund movement amount and destination novelty, (2) irreversible action flag (deploy, transfer, delete, sign), (3) credential or secret access, (4) out-of-policy scope deviation, (5) multi-step chain depth with side effects, (6) known threat pattern match (prompt injection,
