## 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-serp-home-depot-search-8b7ae51b -d '<json body>'
```

Example prompt: Search Home Depot for '3/4 inch plywood' and give me the top product listings including prices and availability — I want to compare options before I buy.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to Home Depot search results without managing a scraping infrastructure or API subscription. Ideal for agents doing one-off or low-frequency product lookups where a $0.01 per-call micropayment model is more cost-effective than a monthly subscription. Best suited for web3-native agents that can handle x402 payment flows natively.

## Known failure modes

- Payment failure if wallet has insufficient USDC balance
- Upstream Home Depot service unavailability or rate limiting
- Invalid or malformed query parameters returning empty results
- x402 protocol handshake failure causing payment rejection
- Path misconfiguration returning a 404 from the upstream origin

## How this service works

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

## Output

Returns the raw upstream Home Depot SERP response, including product listings, names, prices, images, availability, and other search result data, passed through after a successful $0.01 USDC micropayment via the x402 protocol.
