How this service works
Source-backed API reports for wallet-enabled agents. Pay per successful call in Base USDC.
Output
A JSON object containing a status field (ok/denied/review) and an evidence_receipt with a SHA-256 hash that cryptographically attests to the policy decision, enabling auditability of every verdict.
Example use cases
Agent payment pre-authorization check
“Before you pay the $75 invoice to that new supplier, run it through my spend policy — my ceiling is $200 and only pre-approved vendors can be auto-paid, so reject it if the destination is unknown.”
Autonomous agent budget enforcement
“My AI shopping agent is about to spend $340 on restocking supplies — check whether that's within my $500 weekly budget ceiling and return a verdict with a receipt I can audit later.”
Flag over-limit transactions for human review
“My agent tried to send $1,200 to an address not in my approved list — run this through the budget guard with my policy ceiling of $500 and tell me if it should be blocked or sent to me for manual approval.”
Technical details
Endpoint
POSThttps://api.vinoandviews.online/v1/agent-budget-guard?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, auditable spend-policy check before an autonomous agent executes a financial transaction. It is ideal for agent safety guardrails where you supply your own policy rules and want a cryptographic receipt of the verdict. Prefer this over ad-hoc logic when unknown destinations must be flagged for human review rather than auto-approved.
Side effects
- Unknown destination triggers a 'review' verdict rather than approve/deny — agent must handle the review state explicitly
- Malformed policy input returns a validation error with no verdict
- Amount or ceiling fields with incorrect types cause request rejection
- Missing required body fields result in a 400-level error
- Policy conflicts (e.g. amount equals ceiling exactly) may produce edge-case verdicts depending on policy strictness
