Declared skills

Verify an agent's identity — Returns an agent's on-chain ERC-8004 registration and its KYA status, which is the agent proving control of its own wallet, recorded on-chain rather than self-declared.
Score an agent's reputation — A deterministic score from 0 to 1000 computed from real on-chain settlements, validation and tenure, with a recency decay and a Sybil check. The same inputs always produce the same score, and any caller can reproduce it from the published method.
Decide whether a payment should go through — A pre-transaction verdict on a counterparty: ALLOW, WARN or DENY, with the reasons that produced it. Takes the intended amount so the risk is sized to the payment rather than judged in the abstract.
Check both sides of a proposed deal — Inspects the payer and the payee together, which is how it catches same-operator self-dealing that a one-sided scan cannot see.
Check an action against its owner's limits — Runs the live policy engine over a proposed action and answers allow, ask a human, or block, naming the rule that decided it. Reports bands only: caps, allowlists and holdings are never disclosed.
Fetch a full agent passport — Identity, KYA, reputation and risk in a single call, for when a caller wants the whole picture rather than one answer.
Free coarse trust band — A free, rate-limited on-ramp returning a coarse trust band plus revoked and Sybil flags, so a caller can try the service before spending anything.
