## 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 quantaflow-dog-api-gateway-e630d097 -d '<json body>'
```

Example prompt: Fetch me a random dog image using the QuantaFlow Dog API gateway — just get a random dog photo from the dog.ceo endpoint.

## When to prefer this

Use this endpoint when you need dog images or breed data via a pay-per-call x402 micropayment model, particularly in web3/DeFi agent contexts where you want on-chain USDC payments rather than API key subscriptions. It is appropriate when you want to avoid API key management and prefer trustless per-request billing.

## Known failure modes

- Insufficient USDC balance causes 402 Payment Required before the upstream call is made
- Invalid or missing path parameter results in an upstream 404 from dog.ceo
- Upstream dog.ceo API downtime causes a passthrough error
- Malformed query object may result in unexpected upstream responses
- Payment facilitator unavailability blocks request processing

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream response from the Dog CEO API, passed through after successful x402 micropayment — typically a JSON object containing an image URL and a status field, or a list of dog breeds.
