How this service works
Guardian Policy Check — test a proposed pay (amount, host, network, risk) against a sealed spend-policy token. Returns ok + reasons. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a JSON object with an 'ok' boolean indicating whether the proposed payment passes the sealed policy, plus an array of pattern-based reasons explaining which policy rules were matched or violated (amounts, hosts, networks, risk thresholds). Does not issue verdicts — returns patterns and signals for the agent to act on.
Example use cases
Pre-payment policy gate for autonomous agent
“Before my agent pays any x402 skill on Agentic Market, I want you to check the proposed payment of 1000 atomic units to that resource URL against my guardian policy token — confirm it's within policy before proceeding.”
Spend-limit enforcement for AI expense control
“My spend policy only allows payments under 50000 atomic USDC per host — can you run this proposed 45000 atomic payment to https://data.provider.com through my guardian policy token and confirm it passes?”
Network and risk compliance check before settlement
“I have a sealed policy token that restricts payments by network and risk score — check whether this 200000 atomic payment to the Base network host fits within my policy before we settle it.”
Technical details
Endpoint
GEThttps://cyre.dev/api/policy/checkWhen to prefer
Use this endpoint when an AI agent needs to enforce a pre-configured spend policy before executing any x402 payment — particularly when the policy is sealed into a token and you want pattern-based compliance checking rather than ad-hoc risk scoring. Prefer this over CYRE Guardian Lockbox Match when you don't have a pre-pay lockbox/intentHash and just need to check a proposed payment against standing spend rules. Prefer over Guardian Pay-route Oracle when the decision is policy-compliance (not counterparty risk) focused.
Side effects
- Missing or invalid token parameter returns an error — token must be a valid sealed spend-policy token
- Invalid amountAtomic format (non-numeric string) may cause parse errors
- resourceUrl not matching any policy pattern returns ok:false with pattern reasons
- Network or host not covered by the policy token returns a non-ok result
- Expired or tampered policy token returns an authentication/validation failure
- Unsupported HTTP method (only GET, HEAD, DELETE allowed) returns a schema validation error
