How this service works

Locus public pay-per-use API

Output

Returns a JSON object containing an array of search results (each with URL, title, and snippet), optionally an AI-generated answer summarizing the results, optionally related images, optionally raw HTML content, plus payment settlement details (amount in USDC) and a request ID for status tracking.

Example use cases

Breaking news research on a topic

“Find me the latest news articles about the EU AI Act from the last 3 days — up to 8 results, news topic, and include an AI-generated answer so I get a quick summary.”

Competitor intelligence from specific sites

“Search for pricing and product announcements from Stripe and Square only — include those two domains, use advanced search depth, and give me up to 5 results with an AI answer.”

Country-specific market research

“Do a web search for electric vehicle adoption trends in Germany, filter results to the last 30 days, use advanced depth, and return up to 10 results with an AI-generated summary.”

When to prefer

Choose this endpoint when you need AI-optimized, up-to-date web search with fine-grained control over recency, domain inclusion/exclusion, country targeting, and search depth — especially when you want an AI-generated answer summary alongside raw results. Prefer it over generic search APIs when the agent needs Tavily's ranking quality and the convenience of x402 micropayment billing without managing API keys separately.

Side effects

Empty or vague query returns low-relevance results
Overly restrictive domain filters may return zero results
'days' filter set too narrow may exclude all recent content
Advanced search depth may increase latency slightly
Invalid country code may fall back to default or return error
Payment failure via x402 will block the request from completing
