## 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-google-trends-autocomplete-via-x402-55667b8e -d '<json body>'
```

Example prompt: Can you fetch Google Trends autocomplete suggestions for the keyword 'electric vehicles' so I can see what related searches are trending right now?

## When to prefer this

Choose this endpoint when you need Google Trends-specific autocomplete data (not just general search suggestions) for SEO research, content strategy, or trend analysis, and you want to pay per call via USDC micropayments without a subscription commitment. Prefer this over direct SerpAPI integrations when you need an x402-compatible pay-as-you-go model suitable for autonomous AI agents.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
- Invalid path or query parameters: upstream returns 400 Bad Request or empty results
- Rate limiting from upstream SERP provider: returns 429 Too Many Requests
- Upstream provider unavailable: returns 502 or 503 gateway error
- Malformed JSON body: request forwarding fails with 400 error
- Query returns no suggestions: empty autocomplete list for niche or restricted terms

## How this service works
