How this service works
Compare caller-supplied requested spend with supplied budget and transaction limits. Advisory policy calculation only; it does not reserve funds, enforce a wallet limit or authorize payment.
Output
Returns an advisory policy result (e.g. ALLOW, REVIEW, or BLOCK) indicating whether the requested spend fits within the supplied remaining budget and per-transaction limit, along with reasoning. Does not reserve, hold, or authorize any funds — purely advisory.
Example use cases
Pre-purchase spend gate for autonomous agent
“My agent 'agent-456' wants to spend $30 USDC on a data API call. I have $75 USDC remaining budget and a $50 USDC per-transaction cap. Run a budget check so I know if it should proceed or needs review.”
Auto-approval threshold enforcement
“Check if a requested spend of $120 USDC is allowed for agent 'agent-789' with a $200 remaining budget and $150 per-transaction limit in USDC — but flag anything over $100 for manual review.”
Zero-headroom budget block detection
“I need to know if agent 'agent-001' can still spend $60 USDC on an 'api_purchase' when its remaining budget is only $10 USDC and the per-transaction limit is $50 USDC. Tell me if it should be blocked.”
Technical details
Endpoint
POSThttps://nohands-coinbase-bazaar.bytoken2023.workers.dev/x402/v1/policy/budget-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a lightweight, advisory pre-spend check before executing a payment — especially when enforcing per-transaction caps, remaining budget headroom, or auto-approval thresholds without any side effects. Prefer it over full authorization flows when you only need a policy decision, not a fund reservation.
Side effects
- Invalid number format in requested_amount or remaining_budget returns a validation error
- requested_amount or remaining_budget fields missing causes a 400 bad request
- Currency enum value not in [USDC, USDT, USD] is rejected
- Pattern violations on agent_id or purpose fields cause schema errors
- Service unavailability returns a 5xx error
