How this service works
Keyword suggestions for a seed: autocomplete expansions, related queries, questions — ranked across Google, YouTube, Bing.
Output
A ranked list of keyword suggestions for the given seed, organized into categories such as autocomplete expansions, related queries, and question formats, sourced from one or more of Google, YouTube, and Bing. Each suggestion reflects real user search behavior across the selected platforms.
Example use cases
Content cluster ideation for a blog
“I'm writing content about 'intermittent fasting' — can you pull all the keyword suggestions, questions, and autocomplete expansions for that seed from Google and YouTube in English for the US?”
YouTube channel keyword research
“I want to grow a YouTube channel about 'home woodworking'. Can you get me keyword suggestions just from YouTube for that seed in English, going deep with the full a-z expansion?”
Localized SEO for non-English market
“I need keyword ideas for 'seguro de salud' targeting Spanish speakers in Mexico — pull suggestions from Google and Bing in Spanish with questions and modifiers included.”
Technical details
Endpoint
GEThttps://citable.run/v1/keyword-suggest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need broad keyword discovery from actual search engine autocomplete data across multiple platforms simultaneously. It is ideal for content ideation, SEO planning, and competitive research where you want real user-generated query patterns rather than static keyword databases. Prefer it over single-engine alternatives when cross-platform coverage (Google + YouTube + Bing) matters, or when question-format and long-tail expansions are needed alongside standard autocomplete.
Side effects
- Missing required 'seed' parameter returns a 400 error
- Seed exceeding 80 characters is rejected
- Unsupported language or country code may return empty results or an error
- Invalid source value in comma-list causes rejection
- Payment failure via x402 protocol blocks the request
- Rate limiting may return 429 if too many calls are made quickly
