## 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-x402-api-gateway-alchemy-apechain-mainnet-8dc06459 -d '<json body>'
```

Example prompt: Can you look up the latest block number on ApeChain mainnet using the Alchemy gateway — just forward a GET to the root path with no extra body?

## When to prefer this

Choose this endpoint when you need pay-per-use, no-subscription access to Alchemy's ApeChain mainnet RPC without managing API keys. It is ideal for agents making occasional or variable-volume ApeChain queries billed at $0.01 USDC per call via x402 micropayments. Prefer it over direct Alchemy access when operating in a web3-native, wallet-based payment context.

## Known failure modes

- Payment failure: insufficient USDC balance or invalid x402 payment header returns 402 Payment Required
- Invalid path: unrecognized Alchemy API path returns upstream 404 or error
- Malformed JSON body: if body is not valid JSON, upstream may return a 400 or RPC error
- ApeChain node unavailability: upstream Alchemy outage returns 502 or 503
- Rate limiting: excessive calls may trigger Alchemy upstream rate limits returning 429

## 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 Alchemy's ApeChain mainnet API is passed through unchanged, including the response body (typically JSON-RPC result) and the original content type header. No transformation is applied — what Alchemy returns is what you receive.
