How this service works
Guardian Spend Policy — seal max spend, allow/deny hosts, networks, and risk ceiling into a signed policy token other agent middleware can enforce. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
A signed policy token encoding the actor's max spend (in atomic units), host allow/deny patterns, permitted networks, and risk ceiling. This token is consumed by downstream agent middleware as an enforcement artifact — it carries patterns, not verdicts, so middleware makes the final call.
Example use cases
Cap autonomous agent wallet spending
“Generate a Guardian spend policy token for my agent at address 0xAbc123 with a maximum spend of 1000000 atomic units — I want middleware to enforce this ceiling before any payment goes through.”
Restrict agent to approved payment hosts
“Seal a spend policy for actor 0xDef456 that only allows payments to whitelisted hosts and blocks everything else, with a max spend cap of 500000 atomic units.”
Set risk ceiling for DeFi agent
“Create a signed CYRE Guardian policy for actor 0x789Ghi that encodes a risk ceiling so my agent's middleware will block any transaction above our approved risk threshold.”
Technical details
Endpoint
GEThttps://cyre.dev/api/policyWhen to prefer
Use this endpoint when you need a portable, signed enforcement artifact that downstream middleware or agent orchestrators can consume to gate payments — specifically when you want to encode spend ceilings, host patterns, and risk ceilings into a single token rather than enforcing rules ad hoc in your agent logic. Prefer this over runtime risk checks when you want pre-committed, tamper-evident spend policies that travel with the agent context.
Side effects
- Missing required 'actor' query parameter returns an error
- Invalid or unrecognized actor address format causes rejection
- Payment of 0.002 USDC not received results in HTTP 402 and no token issued
- Malformed maxSpendAtomic value (non-numeric string) may cause parsing error
- Network timeout or service unavailability returns 5xx error
