How this service works
68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.
Output
Returns a JSON object with three fields: 'ok' (boolean indicating successful processing), 'allowed' (boolean indicating whether the budget allocation permits the operation), and 'summary' (a human-readable string explaining the allocation decision after x402 payment settlement).
Example use cases
Verify API call stays within spending limits
“Check if my next API request would exceed the budget I've allocated this month on x402, and let me know if it's approved or if I need to top up my account.”
Authorize bulk data deletion operation
“I'm about to delete a large batch of records—can you verify through the x402 trust layer that this DELETE operation is within my current budget before I proceed?”
Validate marketplace transaction before execution
“A vendor wants to fetch pricing data from our partner exchange, but I need to make sure this HEAD request won't blow past our weekly API budget. Can you check if it's allowed and show me the reasoning?”
Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/budget-allocator/run?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically evaluate whether a specific HTTP operation (GET, HEAD, DELETE) is permitted under a pre-defined budget within the x402 trust infrastructure, especially when budget enforcement needs to be tied to on-chain payment settlement. Prefer this over generic access control APIs when operating in a Web3/x402 payment context where budgets are allocated via USDC micropayments.
Side effects
- Payment not settled — x402 payment failed or was not processed, returning 402 Payment Required
- Invalid HTTP method provided — only GET, HEAD, DELETE are accepted enum values
- Missing required 'input' object in request body — returns 400 Bad Request
- Network or chain latency causing timeout during budget evaluation
- Insufficient budget — request denied with allowed: false and explanatory summary
