## 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-mid-price-calculator-9d39816b -d '<json body>'
```

Example prompt: What's the mid price if the bid is 99.5 and the ask is 100.5?

## When to prefer this

Choose this endpoint when you need a simple, verifiable, pay-per-call mid-price calculation without any signup friction. It is ideal for AI agents that need real-time midpoint computation in a financial context and want cryptographically verifiable delivery settled in USDC. It does not require pre-provisioned API keys or subscriptions, making it perfect for ephemeral or automated agent workflows.

## Known failure modes

- Missing ask or bid field returns an error
- Non-numeric values for ask or bid cause validation failure
- Ask lower than bid may produce unexpected results
- Payment failure via x402 prevents API access
- Network timeout on the Base or Solana payment layer

## How this service works
