Decide whether an autonomous agent should pay one merchant, host, or wallet, and return trusted, unknown, suspicious, or block. Use immediately before a payment, a checkout redirect, or a transfer to a new 0x address. Do not use it to send money, to score a dollar amount (score_spend), or to read remaining checks (paycheck_get_quota). Does not sign transactions or hold wallet keys. target is a bare domain, an https URL, or a 0x address with 40 hex characters. amount_usd and category are ignored, so changing them does not change the verdict. trusted is only the published allowlist of known AI and developer APIs on https port 443. A new or random domain is never trusted. A wallet is never trusted. If the URL contains an embedded 0x address, this scores the host only; pass the bare address to score the wallet. api_key, when set, is a PayCheck pc_live_ key, not a Toolweather tw_ key from get_api_key and not a SpendGate sg_live_ key. Uses PayCheck's quota (100/day anonymous or an anon: bundle client, 1,000/day with a pc_live_ key or a hex Toolweather bundle client), then $0.001 via x402, not the Toolweather check quota. The same target for the same caller is idempotent for 60 seconds and does not consume a second check.
