Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-twap-simple-calculator-e99e1bce -d '<json body>'
```

Example prompt: Calculate the simple TWAP for this price series: [10, 11, 12, 11] — I need the time-weighted average so I can smooth out the noise before placing my trade.

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001 USDC), stateless TWAP calculation from a raw array of prices without setting up your own math logic. Ideal for AI agents that gather price samples from multiple sources and need a single smoothed value before making a trade decision or risk assessment. Prefer this over general-purpose math APIs when you want verifiable, pay-per-result delivery with no signup friction.

## Known failure modes

- Empty or missing prices array returns an error
- Non-numeric values in the prices array cause a validation failure
- Payment failure via x402 protocol blocks the request
- Malformed JSON body results in a 400 error
- Single-element array may return a trivial TWAP equal to the sole value

## 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 containing the number of price samples used (n), the computed simple TWAP value (twap), and a schema identifier string (schema: 'delx/util-twap-simple/v1') confirming the calculation method.
