## 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-memo-endpoint-08d839c5 -d '<json body>'
```

Example prompt: Can you send this memo to Tempest and get back the result: 'Summarize the key risks of investing in small-cap crypto tokens'?

## When to prefer this

Choose this endpoint when you need to send a free-text memo or natural language request to the Tempest service specifically via the whatchuneed aggregated pay-per-call platform. Useful when you want to pay per call in USDC via x402 without managing separate API keys. Best when the Tempest memo computation or lookup fits your use case and you are already operating within the whatchuneed ecosystem.

## Known failure modes

- Empty or missing 'input' field causes validation error
- Tempest service unavailable returns non-200 status
- Malformed input string may produce empty or null result object
- Payment failure via x402 protocol prevents call from completing
- Ambiguous or unsupported memo content may return a generic or empty result
