Delx Commerce Agent Result Budget Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Checks whether a single API call cost and projected daily spend fall within a configured per-call and per-day USDC budget

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the call is within the per-call budget (within_call_budget), whether it is within the daily budget (within_day_budget), the projected total daily spend after this call (projected_day_usdc), and verifiable evidence including an input SHA-256 hash confirming no data was retained and no external calls were made. Status field reports 'pass' or equivalent.
Example use cases
Pre-flight guard for agent spending
“Before my agent makes another API call costing $0.001 USDC, check if it's still within budget — it has spent $0.015 today, the daily max is $0.03, and the per-call ceiling is $0.002.”
Enforce daily USDC cap for agent fleet
“I need to enforce a $0.10 daily budget across my agent's API calls — it's spent $0.098 so far today and the next call costs $0.001. Will this call exceed the limit?”
Budget compliance check before result delivery
“My agent is about to pay $0.001 for a result. Daily budget is $0.05, spent today is $0.04, max per call is $0.003 — can it proceed without going over?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-result-budget-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a lightweight, verifiable, in-memory budget gate before executing any pay-per-result API call. It is ideal for enforcing per-call and per-day USDC spending limits without storing sensitive data, particularly within agent orchestration loops on Base or Solana. Prefer this over custom budget logic when you want a tamper-evident SHA-256 evidence receipt confirming no retention.
Side effects
- Missing or malformed numeric string inputs may cause computation errors
- If spent_today_usdc plus call_usdc exceeds maximum_day_usdc, within_day_budget returns false (not an error, expected behavior)
- If call_usdc exceeds maximum_call_usdc, within_call_budget returns false
- Payment of $0.001 USDC required via x402; insufficient funds or wrong chain will block the call
- Non-numeric string values in USDC fields will likely result in a 400 error
