How this service works
Search Aggregator fast tier: Serper web search (titles, links, snippets), fixed price $0.01 USDC. POST JSON body {query (required), max_results (optional 1-20, default 5)}. Mode is fixed by the path — no mode field needed, the quoted price is always the settled price.
Output
Returns a JSON object containing the original query, an array of up to 20 result objects (each with URL, title, snippet, content, source_provider, and published_date), an optional synthesized answer string, a list of providers_used (Serper), latency in milliseconds, and any warnings.
Example use cases
Real-time news lookup for research
“Search the web for 'OpenAI GPT-5 release date' and show me the top 8 results with titles, URLs, and snippets.”
Competitive intelligence gathering
“Find me the top 10 web results for 'Stripe vs Braintree payment processing fees 2024' — I want titles, links, and short descriptions.”
Quick fact-checking on a topic
“Search for 'WHO recommendations on sugar intake per day' and return up to 5 results so I can verify the current guidelines.”

Endpoint
GEThttps://x402-production-d123.up.railway.app/search/fastWhen to prefer
Choose this fast-tier endpoint when you need quick web search results (titles, links, snippets) at low cost ($0.01 USDC) and low latency. Prefer it over the deep tier when full page content and multi-provider synthesis are not required, or when budget and speed matter more than depth of results.
Side effects
- Invalid or missing query parameter returns an error
- max_results outside 1-20 range may be rejected or clamped
- Payment failure (x402) if USDC balance is insufficient
- Serper upstream outage causes no results or timeout
- Rate limiting if too many requests are made in quick succession
