How this service works
Search volume, CPC, competition, keyword difficulty, intent, keyword ideas and Google Trends, paid per call over x402 (USDC on Base). No account, no API key.
Output
Returns two lists of related Google Trends queries for the keyword: 'top' (up to ~25 queries with 0-100 relative popularity scores) and 'rising' (queries with % growth vs the prior period). Also includes market metadata (country name, location code), the timeframe queried, the data timestamp, and a pointer to a sibling endpoint for interest-over-time series data.
Example use cases
Content ideation from trending queries
“Show me the top and rising related searches for 'intermittent fasting' in the UK over the past 90 days — I want to find emerging angles for new blog posts.”
SEO query expansion for a campaign
“I'm planning an SEO campaign around 'project management software' — can you pull the top related Google searches worldwide for the past 12 months so I can expand my keyword list?”
Spotting fast-growing search trends
“What are the fastest rising related searches around 'AI writing tools' in the US over the past 30 days? I want to see which queries are spiking so I can jump on them early.”
Technical details
Endpoint
GEThttps://keywords.duoleads.com/v1/related-queries?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what users also search for around a specific keyword — ideal for query expansion, content ideation, or spotting emerging trends. Prefer this over generic keyword volume endpoints when you want related query discovery with trend signals (top vs rising), not just search volume. Choose the sibling trend endpoint if you need the interest-over-time series for the same keyword instead of related queries.
Side effects
- Keyword too short (<2 chars) or too long (>100 chars) — returns validation error, not charged
- Invalid country code format — returns validation error, not charged
- No related queries found for obscure keywords — returns empty top/rising arrays
- Upstream DataForSEO/Google Trends outage — upstream error, charged may not apply
- Response latency up to ~30 seconds on live calls — agent timeout if not configured appropriately
- Worldwide results returned when country omitted — may be unexpected if regional data was intended
