## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-agent-result-budget-check-db6e567b -d '<json body>'
```

Example prompt: Before making the next paid call, check if spending $0.001 USDC is within budget — I've already spent $0.021 today, my daily cap is $0.05, and my per-call limit is $0.005.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
