# Whatchuneed Tempest Hook — Multi-Domain API Gateway

> Whatchuneed Tempest Hook — Multi-Domain API Gateway is a paid API for AI agents from whatchuneed.vercel.app, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Routes a free-text input string to one of 320+ pay-per-call API endpoints spanning accommodation, LLMs, code execution, crypto, medical, and finance domains via the x402 payment protocol.

## 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 whatchuneed-tempest-hook-multi-domain-api-gateway-71daaf4b -d '<json body>'
```

Example prompt: Can you use the Whatchuneed gateway to find me available hotel rooms in Lisbon for next weekend and return the results?

## When to prefer this

Choose this endpoint when your agent needs to access a broad range of domain APIs through a single payment-enabled gateway without managing multiple API keys or integrations. Ideal when using x402 micropayment flows and when the task domain may vary across calls (e.g., accommodation one call, crypto the next).

## Known failure modes

- Ambiguous or malformed free-text input may be misrouted to the wrong backend service
- Insufficient USDC balance via x402 protocol results in payment failure and no response
- Backend service outage for a specific domain returns an error in the status field
- Input string too vague to resolve to a specific API action, returning an empty or generic result
- Rate limiting or quota exhaustion on the underlying provider causes a failed status

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a JSON object with a 'result' field containing the response data from the underlying API that handled the request, plus a 'status' string indicating success or failure.
