## 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 x402-donnyautomation-com-search-autocomplete-keyword-research-api-a302ac25
```

Example prompt: What are the most common things people type into Google when they search for 'electric vehicles'? Give me the full expansion with questions and comparisons, in English for the US market.

## When to prefer this

Choose this endpoint when you need real, live search demand data straight from Google Autocomplete rather than static keyword databases. It is especially useful when you want question and comparison variants automatically expanded and filtered, saving you from running dozens of separate API calls. Prefer it over static keyword tools when freshness and real user intent signal matter, and when you need results normalized to stay on-topic.

## Known failure modes

- Missing required 'q' parameter returns a 400 error
- Query exceeding 200 characters may be rejected or truncated
- Invalid language or country codes may fall back to defaults or return an error
- Network timeout if Google Autocomplete upstream is slow
- No results returned for very obscure or novel queries with no search history

## How this service works

Live Google Autocomplete for a topic, expanded across question modifiers (how, what, why, is, can, does) and comparison modifiers (vs, or), split into suggestions, questions and comparisons. Off-topic rows are dropped and counted. Requires ?q= (max 200 chars); optional ?depth=full|basic, ?country=us, ?lang=en. Errors: 400 missing_q|q_too_long|bad_depth, 504 suggest_timeout. This is DEMAND (what people type), not ranked results - for those use /search.

## Output

A structured response containing three categorized lists: suggestions (direct completions of the query), questions (how, what, why, is, can, does expansions), and comparisons (vs, or expansions), plus a count of off-topic rows that were filtered out because they dropped the original term.
